- Do not crush, crimp, or sharply bend the fiber-optic cable. Avoid making loops in the fiber-optic cable smaller than 5 inches (12.7 cm).
- Do not twist the fiber-optic cable; twisting the cable will stress the optical fibers.
- Do not allow kinks or knots to develop in the fiber-optic cable.
- Avoid putting tension on the fiber-optic cable.
- Do not pull or jerk the fiber-optic cable, especially when kinks or knots are present.
- Do not drop the sensor head or comp box assembly since damage and misalignment of the internal optical components can result.
- Avoid over-bending the sensor tip cables; do not exceed the minimum bend radius of 2.0 inches (5.1 cm).
- Avoid crushing the cables by accidentally running over the cable with a chair wheel or by dropping a heavy object onto the cable.
- Never support the weight of the sensor head or comp box by the fiber-optic cable.
- Store the measurement system in the supplied carrying case when not in use.

Clearance requirements
The unique common mode voltage range of the measurement system allows it to be used in the presence of high frequency/high voltage common mode signals. It is important to observe all precautions while using this product.
WARNING:Electrical shock can occur while using this measurement system. The system is intended to isolate the operator from hazardous input voltages (common voltages); the plastic case of the sensor head and the shield on the sensor tip cable do not supply safe isolation. Maintain the safe clearance from the sensor head and sensor tip cable while the measurement system is connected to the energized circuit as recommended in this document. Do not access the RF Burn Hazard Zone while taking measurements on a live circuit. |
While measuring high frequency common mode signals, there is a risk of RF burns. Refer to the following derating curve to identify the danger areas. Measuring common mode signals within the gray shaded area can result in RF burns within 1 m (40 in.) of the sensor head and earth ground.
The following figure shows the components of the measurement system and the potential RF burn area when working with hazardous voltages. The RF burn area of 1 m (40 in.) is indicated by the dashed lines surrounding the sensor head.
Controls and indicators
A description of the controls and indicators on the compensation box.

- SELF CAL button and LED indicator: Press to start self-calibration routine. For more information on the state of the LED, see Table 2
- INPUT Termination button and LED indicator: With no tip attached, press to toggle the sensor head between 50 Ω and 1 MΩ termination. For more information on the state of the LED, see Table 3
- MENU button: Press to open the Probe Vertical menu on the oscilloscope.
- ALT mode indicator: Displays special information about the probe. For more information, see Table 4
Cable flags
Flags on the cable provide high-level specifications for connecting to the DUT. They also provide a potential RF burn hazards warning and a self-calibration notification.
Sensor tip cable
Each sensor tip cable has a label that provides the maximum dynamic range and displays the attenuation factor.
Connecting to a circuit
WARNING:This measurement system contains laser sources; exposing these laser sources may cause laser exposure. Except for the sensor tip cables on the sensor head, do not remove any plastic or metallic covers from the sensor head or comp box or attempt to disassemble the product. |
WARNING:Do not connect the measurement system to an energized circuit to avoid the risk of shock. Always de-energize the circuit-under-test before installing or removing the tip cable from the circuit-under-test. The plastic case of the sensor head and the shield tip of the sensor cable do not supply the isolation. |
WARNING:To avoid the risk of electrical shock or RF burns while the DUT is energized, do not touch the sensor head or sensor tip cable while taking measurements. Always keep a 1 m (40 in.) clearance from the sensor head during the measurement. Figure 2
Be sure to check the maximum ratings and derating curve for more information on the RF burn hazard zone. Figure 1 |
CAUTION:To avoid possible damage to the equipment, do not connect the coaxial (common) shield of the sensor tip cable or SMA input to the high impedance portion of a circuit. The additional capacitance can cause circuit damage. Connect the coaxial (common) shield to the low impedance section of the circuit. |
Note:Touching the sensor head or sensor tip cable when measuring a high frequency common mode signal increases the capacitive coupling and can degrade the common mode loading on the circuit-under-test. |
WARNING:To prevent the arc flash caused by a different potential, do not place the sensor head or sensor tip cable on the circuit that has the different voltage. |
The following steps describe the process for connecting the measurement system between an oscilloscope and the DUT.
-
Verify the DUT is not connected to an energized circuit.
-
Connect the compensation box to one of the channels on the oscilloscope.
-
Install the sensor tip cable to the sensor head.
-
Line up the sensor tip cable with the sensor head.
Take care to avoid bending or twisting the sensor tip cable assembly during this process.
-
Connect the SMA connector of the sensor tip cable to the sensor head. Use the SMA wrench to tighten the SMA cable to 4 to 5-in lbs.
Use the adjustment tool that was shipped with your probe.
-
-
Connect the sensor head to the included bipod or a similar support.
This support keeps the sensor head steady reducing the potential mechanical stresses at the electrical connection point of the DUT. The support also keeps the sensor head away from surrounding circuits and conductive objects to minimize the parasitic capacitive coupling to these surroundings.
Note:To obtain the most accurate measurement, allow the measurement system to warm up for 20 minutes. Then perform the self-calibration before connecting the tip cable to the DUT and taking the measurement. -
Connect the sensor tip cable end to the DUT. If you are using MMCX sensor tip cable, connect it to an MMCX connector on the DUT or to a square pin adapter on the DUT. The adapters connect to square pins with either 0.100-inch (2.54 mm) spacing or 0.062-inch (1.57 mm) spacing. Figure 1
If you are using one of the square pin sensor tip cables, connect it directly to the square pins on the DUT. Connecting the sensor tip cables
-
Set up the controls on the oscilloscope.
-
Apply power to the DUT to take the measurement.
Self-calibration
The TIVP contains a self-calibration function that corrects gain accuracy, DC offset, and frequency response. These parameters change as the probe warms up to the operating temperature and remain constant once the temperature reaches steady-state. After the probe warms up, self-calibration is recommended when there is a 5°C change in ambient temperature. An indicator LED on the compensation box provides the status of the self-calibration. See the Controls and indicators for more information on the LEDs.
To check the status of the self-calibration programmatically, use the SELFCAL:STATE? PI
command to determine whether a self-calibration is RECOMMENDED
, RUNNING,
or PASSED
.
Before performing critical measurements, run a self-calibration to ensure the probe is compensated.
Note:The sensor tip cable does not need to be removed from the test point to successfully complete the self-calibration. |
- Connect probe to an oscilloscope channel.
- Press the SELF CAL button on the probe compensation box. The Self Cal indicator LED will blink while self-calibration is in process.
- Self-calibration is complete when the indicator LED displays green.
To run the self-calibration programmatically, use the CH<x>:PROBE:SELFCAL EXECUTE PI
command. The connected channel is specified by "x".
The TIVP probe takes about 20 minutes to warm up. During this time, acquired waveforms may show obvious aberrations. The following screen shot shows how a 1 KHz square wave appears at the beginning of the warm-up period. Notice how the probe appears to be uncompensated.
Note:When moving a probe that has fully warmed up to a new oscilloscope channel, you must give the probe another 5 minutes to warm up on the new channel. |
After 20 minutes, most of the aberrations are gone. Self-calibration can be used before the probe reaches its operating temperature, however those self-calibration settings will become invalid a few minutes later as the internal temperature changes.
Self-calibration takes less than 2 minutes to complete. Your signal does not need to be disconnected from the probe head when running self-calibration. The LED next to the SELF CAL button on the compensation box will flash yellow during the operation. When complete, the LED will either turn green (passed) or red (failed).
The SelfCal Status indicator in the oscilloscope Probe Setup menu indicates whether self-calibration is required.
Note:In 4/5/6 Series Mixed Signal Oscilloscopes, commands are available to start and monitor self-calibration and a status query to determine if self-calibration is needed. |
AutoZero
AutoZero and self-calibration work on different parts of the measurement system. Self-calibration optimizes measurements through adjusting parameters in the probe. AutoZero is an oscilloscope function and is used when a displayed waveform is not centered correctly (for example; due to a small DC offset error). AutoZero automatically runs after self-calibration. It is not necessary to disconnect your signal from the probe when running a self-calibration. However, when AutoZero is run by itself, the signal must not be present.
When the TIVP changes between its internal ranges it may be beneficial to run an AutoZero from the oscilloscope. The TIVP internal range will change in Auto Range mode when the Vertical scale of the oscilloscope is changed. The probe internal range will also change in Manual Range mode if a different range is selected from the Probe Setup menu in the channel vertical settings.
Menu button
Press the MENU button on the comp box to view the Probe Setup menu on the oscilloscope.
Use the menu options on the oscilloscope to change the probe settings.
Ranges
The measurement system has a variety of ranges available for you to select, whether the probe is being used with or without a tip. This allows for tradeoffs to be made between noise and dynamic range depending on the needs of the measurement being made.
CAUTION:To avoid damaging the probe, do not exceed the Peak Voltage rating for a given tip or the probe head. The Maximum Non-Destruct Voltage limit (Peak Voltage) does not increase when the Probe Ranges are changed. For example, the TIVPMX50X limit of ±250 Vpk is the same for all range settings. |
In 4, 5, and 6 Series oscilloscopes, 9 ranges are selectable when Range Mode is set to Manual. The recommended V/div settings are displayed in the table below. The ranges shown are for the probe SMA input and 1X tip. Multiply the range and V/div setting by the tip attenuation to get the values for a sensor tip cable.
4/5/6 Series MSO probe ranges | Recommended V/div setting |
---|---|
20 mV | 2 mV/div |
40 mV | 5 mV/div |
80 mV | 10 mV/div |
160 mV | 20 mV/div |
320 mV | 50 mV/div |
640 mV | 100 mV/div |
1.28 V | 200 mV/div |
2.56 V | 500 mV/div |
5 V | 1 V/div |
When using a tip, the label of each sensor tip cable shows the maximum dynamic range and the attenuation factor. For example, the TIVPMX10X has a 10X attenuation factor and displays a signal with a ±50 V differential voltage. When more sensitive ranges are selected, dynamic range is limited. Refer to the Linear differential input voltage range in the specifications table for more information.
Auto Range
In 4, 5, and 6 Series oscilloscopes, the Range Mode is selectable for either Auto Range, or Manual. With the Range Mode set to Auto Range, the probe range is automatically selected when the V/div knob on the oscilloscope is turned. The relationship between probe range and V/div setting matches that shown in Table 1.
Selecting a sensor tip cable
CAUTION:Avoid over-voltage conditions that can damage or degrade the sensor head input termination by selecting the correct sensor tip cable. Selecting the correct sensor tip attenuation factor is crucial to ensure that the sensor head input termination is not degraded or damaged by an over-voltage condition. Select the sensor tip cable that will provide the lowest attenuation possible for the signal being measured. |
When selecting a sensor tip cable for a particular application, consider the following questions:
-
What is the maximum RMS/Peak Voltage at the test point being measured (for example, under a fault condition)?
-
What is the minimum single-ended input resistance that my circuit can tolerate?
-
How large of a signal do I want to display at one time on the oscilloscope?
-
What sensitivity do I need (for example, the minimum V/div setting)?
The following table will help you select the correct sensor tip cable. Start at the top of the table and work down. Choose the first tip that meets all of your criteria.
Sensor tip cable | Most sensitive V/div setting | Dynamic range | Maximum non-destruct voltage (DC + pk AC) | Single-ended input resistance |
---|---|---|---|---|
TIVPWS500X | 500 mV | ±2500 V | 3300 Vpk | 40 MΩ |
TIVPSQ100X | 100 mV | ±500 V | 600 Vpk | 9.75 MΩ |
TIVPMX50X | 50 mV | ±250 V | 300 Vpk | 9.75 MΩ |
TIVPMX10X | 10 mV | ±50 V | 250 Vpk | 10 MΩ |
TIVPMX1X | 1 mV | ±5 V | 100 Vpk / 5 VRMS | 1 MΩ / 50 Ω |
SMA Input 1 MΩ | 1 mV | ±5 V | 100 Vpk | 1 MΩ |
SMA Input 50 Ω | 1 mV | ±5 V | 5 VRMS | 50 Ω |
For maximum non-destruct voltage refer to the Maximum differential input voltage vs frequency derating graphs.
Deskew
Each probe comes loaded with nominal propagation delay values that can be automatically applied through the Vertical menu on the oscilloscope. Deskew accuracy can be improved using a known signal and a deskew fixture. When the timing relationships between waveforms is critical, always deskew your test system with known equipment.
Input offset
The measurement system provides an adjustable input referred offset voltage. This enables viewing a portion of the signal that is off-screen or examining sensitive behavior riding on a larger differential voltage. For example, a 0 V to 600 V step would normally exceed a ±500 V input range. By applying 300 V of offset, the 600 V step is brought into the dynamic range of the probe and can be viewed accurately. Offset is applied by the probe and has a much greater range than the oscilloscope alone.
Input coupling AC or DC
The TIVP sensor head contains both DC and DC Reject input coupling modes. By default, DC coupling is enabled; the mode is switchable through the scope interface or PI command.
The DC input coupling setting provides a direct, DC coupled, electrical path in the sensor head; it accepts all types of signals, including unchanging DC voltages, time-varying DC voltages, AC, and combinations of AC and DC.
When DC input coupling is selected, any applied offset is injected at the sensor head and the offset range depends on the attached tip cable attenuation.
DC Reject input coupling setting provides an AC- only path in the sensor head, removing DC offset from any mixed signal to view the AC component of the signal. DC reject is useful when you measure small amplitude signals superimposed on a large differential offset component.
With DC Reject enabled, offset is applied at the oscilloscope input and is limited by the offset capability of the specific Volts/Div setting on the oscilloscope multiplied by the selected tip attenuation.
Voltage range
The TIVP is designed to enable characterization of high frequency circuits with a wide range of differential voltages in the presence of common mode voltages. Understanding the limits and differences between the voltage ratings as discussed in this section is essential to optimize signal fidelity and measurement accuracy.
Although the common mode voltage range of the probe is very large (>60 kV), the differential input range is limited and depends on the tip attenuation, the gain range selected, and the applied offset.
The input voltage conditions are divided into several different input ranges.
Common mode voltage range
TIVP sensor head is optically isolated from earth ground, making the common mode input range >60 kV. The differential input range is more limited and refers to the signal that can be applied across the probe tip, regardless of the common mode voltage.
Offset voltage range
Offset voltage can be applied through the oscilloscope Vertical menu settings. The input offset capability of the probe extends from ±25 V to ±2500 V depending on the tip used. This offset is applied at the sensor head of probe and can be useful to bring applied signals within the dynamic range (Vdiff) of the probe.
Maximum non-destruct differential voltage range
The maximum non-destruct differential input range is the maximum differential voltage that can be applied to the input without damaging the probe. This is a DC +peak AC rating (no portion of the differential input signal should exceed this value). The maximum non-destruct differential voltage varies from ±20 V to ±2500 V depending of the sensor tip cable being used. Exceeding these levels will cause permanent damage to components of the sensor head. Additionally, the TIVPMX1X and SMA input also have VRMS limits.
Connecting the sensor tip cables
Tektronix provides different types of sensor tip cables to connect to the circuit board.
The MMCX sensor tip series connect directly to MMCX connectors on the circuit board or to probe tip adapters installed on the circuit board. Installing the probe tip adapters
The square pin series sensor tip cables connect directly to the circuit board as shown in the following figure.
The SQPIN series sensor tip cables connect to 0.1-inch (2.54 mm) square pins on the circuit board. The WSQPIN series sensor tip cables connect to 0.2-inch (5.08 mm) square pins on the circuit board.
Probe tip tripod
Use the probe tip tripod to connect the sensor tip cables to adapters on the circuit board. This tripod has flexible hinges to easily position the probe tip cable above the adapter on the circuit board. Tektronix recommends gluing the tripod in place on the circuit board to provide additional support for the sensor tip cables. The following figure shows an example of connecting to an adapter on the circuit board with the tripod; it reduces stresses on the test point.
Installing the probe tip adapters
Tektronix provides two probe tip adapters to connect the MMCX sensor tip cables to pins on the circuit board. The MMCX-to-0.1-inch (2.54 mm) pitch adapter and the MMCX-to-0.062-inch (1.57 mm) pitch adapter.
One end of each adapter has an MMCX socket for connection to an IsoVu MMCX tip cable. The other end of the adapter has a center pin socket and four common (shield) sockets around the outside of the adapter. Notches on the adapters can be used to locate the shield sockets. The procedure for installing these adapters are the same, the main difference is the spacing of the pins on the circuit board.
To install the adapters onto the square pins, line up the center of the adapter with the signal source pin on the circuit board. Use the notch on the adapter to align one of the shield sockets to the common pin on the circuit board. The following figures show examples of lining up the adapters on the circuit board.
To achieve the best electrical performance, especially the CMRR performance and EMI susceptibility, place the probe tip adapter as close as possible to the circuit board.
After lining up the adapters gently push down on the adapter to seat it in place on the circuit board.
When the adapters are firmly in place on the circuit board connect the sensor tip cable to the top of the adapter while using the probe tip tripod to ease the tension off the probe tip cable and adapter. Figure 1
Installing the square pins on the circuit board
The following figure shows the recommended clearance requirements for connecting the adapters to the square pins on the circuit board. The bottoms of the adapters are shown at the top.
The 0.025-inch (0.635 mm) square pins should already be located on the circuit board. Some square pins might have headers installed on the circuit board. Tektronix recommends removing the plastic spacer from the square pins to gain closer access to the circuit board as shown in the following figure to achieve the best electrical performance, especially CMRR. You might need to use a pair of tweezers to remove the spacer as shown in the figure.
Tektronix provides a set of solder pins (0.018-inch (0.46 mm) diameter) to install on the circuit board for use with the MMCX to 0.062-inch (1.57 mm) adapter. Use the soldering aide tool accessory (Tektronix part number, 003-1946-xx) to install these pins on the circuit board.
Note:The solder pins are extremely small and can be challenging to handle. Tektronix recommends using tweezers and a magnifying tool when installing the pins on the circuit board.
The solder pins can be installed around a surface mounted component on the circuit board, but adequate clearance should be maintained for a good electrical connection for the adapter. Figure 1 |
Note:The coaxial (common) shield of the sensor tip cable and tip adapters should always be connected to the lowest impedance point (usually a circuit common or power supply rail) in the circuit-under-test (relative to the sensor tip cable/center conductor) to obtain the most accurate waveform.
|
Use the following steps to install the solder pins using the soldering aide on the circuit board:
-
Carefully insert the solder pins into the soldering aide as shown in the following illustration.
-
Use the soldering aide to hold the square pins in place while soldering the square pins to the circuit board.
-
If necessary apply a small amount of adhesive to further strengthen the connection to the circuit board. However, keep the height of the adhesive to a minimum to provide good electrical contact for the adapter. Figure 1

Common mode rejection ratio graphs
The ability to measure common mode rejection ratios (CMRR) of the IsoVu system below 100 kHz is limited by the dynamic range of test systems. Due to the optical isolation of the IsoVu sensor head, the DC CMRR performance of all tip cables is expected to be greater than 160 dB.

IsoVu measurement system block diagram
The following figure shows a block diagram of the IsoVu measurement system.
The common mode resistance and capacitance to earth ground is shown in the figure. The common mode resistance is shown as R parasitic and is essentially infinite with the IsoVu measurement system since it is galvanically isolated and can be ignored. The common mode coupling capacitance to earth ground and the surrounding circuit is shown as the Parasitic Bridging Capacitance (C parasitic). This parasitic capacitance will be approximately 2 pF when the sensor head is placed six (6) inches (15.25 cm) above a ground plane.
To minimize the effects of common mode capacitive loading consider the following items:
-
Whenever possible, choose a reference point in the circuit-under-test that is static potential with respect to earth ground.
-
Connect the coaxial (common) shield of the sensor tip cable to the lowest impedance point of the circuit.
-
Increasing the physical distance between the sensor head and any conductive surface will reduce the parasitic capacitance.
-
When using multiple IsoVu systems to measure different points in the circuit that do not have the same common mode voltages, keep the sensor heads separated to minimize the capacitive coupling.
