Question: What does the Option 03 on the AWG400 series and AWG500 series do?

Answer: The Option 03 adds digital outputs to the instrument. In the case of the AWG400 series, each channel on the instrument has a 16 bit wide digital output of the data that is feeding that channel's D to A converter. On the AWG410 you have 16, on the AWG420 you have 32 and on AWG430 you get a total of 48 channels of digital stimulus. Each channel has an output pod that provides HI levels of 2.3 min into a 50 ohm load / 4.6 V min into a 1 M ohm load and LO levels of 0.1 V into a 50 ohm load / 0.2 V into a 1 M ohm load. The output connector from the pod to the Device Under Test is a 34 pin header, with 0.025" square pins on .100 inch centers, giving you 16 data lines and clock, with alternating ground pins.

On the AWG510, there are 10 digital outputs that are actually using a separate memory devoted exclusively as a digital channel. This gives you a purely analog channel 1 and a totally independent digital channel. The AWG520 utilizes the channel 2 memory as the source for the option 03 output. On the AWG500 series, "SMB" connectors on the rear panel are the connectors that are used for the option 03. Tektronix sells cables that have a BNC connector on one end and an SMB on the other end to allow you to adapt to other instruments (such as an oscilloscope) if needed.

Question: I have a TPI4202 that needs repair.

Answer: The TPI4000 Series (TPI4202 and TPI4208) were OEM products that Tektronix resold under the Tektronix name.  Tektronix no longer provides repair for these models. Repair for this model/series is through the OEM manufacture, Absolute Analysis.

Question:

When using my TPP0250, TPP0500, TPP1000, or TPP0500B probe, the signal disappears or is intermittent.  What could be causing this?

Answer:

The internal probe tip may have come loose and is causing the loss or intermittency of the signal. The probe tip might also be damaged.

How to check:

Pull off probe Hook tip.

Unscrew black insulation sleeve (item 2).

 

 

 

Look at inner probe tip that is still on the probe.  You will see a metal barrel (item 4) with white or gray insulator at one end and a metal tip at the other end.

 

 

 

Check that the inner probe tip (item 4) is screwed in tight.  Handling/rotating the outer probe retractable hook tip may have loosened the inner tip.  If loose: screw in finger tight.  (If needed, make sure future usage of the retractable hook tip does not unscrew inner tip by making it bit tighter.)  Reassemble probe and check the signal.

If the problem persists, try replacing the tip with the extra cartridge included in your probe packaging (models TPP1000, TPP0500, TPP0500B). After replacing, attempt to perform a probe compensation. If this passes, then the problem is likely resolved. Otherwise, if the probe fails, then send in the probe for replacement.

Note: The label on the inner tip could have shifted and now causing the tip to not fully tighten.  If the label is interfering with the inner tip screwing all the way in, reposition the label and screw finger tight the inner tip.  Then reassemble the probe can check the signal.

Question: What is included in the Tektronix Near Field Probe kit (Tek p/n 119-4146-00) and what are they used for?

Answer: The Tektronix 119-4146-00 Near Field Probe Set is intended to serve as a versatile aid for diagnostic testing of radiated emissions over a broad range of frequencies from below 100 kHz to above 1GHz.  The probe set consist of three (3) magnetic field probes, two (2) electric field probes, 20 cm extension handle, and a custom carrying case.

Includes:

Model #       Description     Response      Impedance

EM-6993       6 cm Loop       H Field           50

EM-6994       3 cm Loop       H Field           50

EM-6995       1 cm Loop       H Field           50

EM-6996       3.6 cm Ball      E Field           50

EM-6997       Stub                E Field           50

The three magnetic field probes are electrically small (i.e. resonant frequency above 1GHz loops of varying sensitivities.  The loops are wound within a balanced Faraday shield that reduces their response to electric fields to a negligible factor.  Each successively larger loop increases sensitivity (independent of frequency) by approximately 12-155dB.  Probes of reduce sensitivity may be of assistance in isolating a emission source more precisely.

The ball and stub comprise the two electric field probes.  Each probe responds primarily to the electric field component and rejects the magnetic field component.

When making before-and-after measurements to determine the effectiveness of an attempted EMI solution, some care should be used to ensure that the measurements are repeatable. Of chief importance is the distance from the probe to the item under test. Even small changes in this spacing can yield large variations in amplitude. The E-field probes are also susceptible to measurement variations due to capacitive coupling to external objects such as equipment chassis, human bodies, large metal objects, etc. The H-field probes do not exhibit this effect.

The response of the E-field probes is essentially omni-directional. The response of the H-field probes is a figure-8 response, typical of a dipole. The primary pickup direction is broadside to the loop, with sharp notches in the pickup pattern in the plane of the loop.

Probe choice is determined by the type of signal under observation, signal strength, and the physical size of the area to be investigated.  Comparison of the response to both H-field and E-field probes will provide the user with some idea as to the relative magnitude of the E-field and H-field of each component, thus providing a clue toward solving the emission problem. The larger probes provide increased sensitivity while the smaller probes permit a more precise location of the emission source.

The kit weight is 4.6 lbs (2.1 kg) with the probes inside and the case dimensions are 11” (28cm)  x  12.75” (32.4 cm) x 4.75” (12.1 cm).

Question: I have saved several waveforms to the internal memory.  How can I transfer them to my computer using Open Choice Desktop?

Answer:

Press the “Save” button to access the Save waveform menu.

Press the “Enter” button to select “Data”.

Use the up/down arrows to select the saved waveform you want to transfer.

Then press the “View” menu to make the waveform active on the display.

When you see the “Data on the screen will be lost. Enter view mode now”? select “YES”.

 

This puts the saved waveform on the active display, which you can now use the Open Choice Desktop screen image capture to transfer the waveform to the PC.

Question: I received the following message about my floating license:  (This is a courtesy note to remind you that the checkout of 1 floating license(s) will soon expire.) Why am I receiving this message when I own the license?

Answer: The Floating Licenses are good forever; however, the checkout of the Floating License is good for for any duration from 4 hours up to 4 years, selectable at the time of check out.  After it reaches selected duration, it will automatically check itself back in.  You just need to re-check it out and set the desired duration.
The default duration is 1 year.
If your Floating License has expired go to TekAMS and recheck it out.
You may review the license checkout details using the TekAMS application at:https://www.tek.com/products/product-license.
