Combining TriMode probing with low noise performance

TriMode probing enhances productivity by enabling differential, single-ended, and common mode measurements with a single probe setup. Connecting a probe to the device under test can be a time consuming activity, especially if the probe has to be set up differently to make all the necessary measurements. TriMode probing improves productivity by reducing setup time because only one setup is needed to make the three different types of measurements. Switching between Differential Mode [A-B], Single-Ended Mode [A-Gnd, B-Gnd], and Common Mode [((A+B)/2)-Gnd] is as easy as a press of a button.


Changing input modes on the probe is as easy as a press of a button

As high speed serial data standards increase in speed and signal swings shrink, probes with high bandwidth coupled with low noise and high sensitivity are increasingly important for making accurate measurements.


12 Gb/s 200 mVpp signal measured with a P7630 and a P76CA-292C coaxial adapter

The MSO/DPO70000DX and DPO/DSA70000D Series oscilloscopes and the P7600 Series TriMode probes were designed to deliver the industry's lowest system noise levels. When used with a P76CA-xxx Coaxial Adapter, the vertical setting on the oscilloscope can be set as low as 3.48 mV/div with a system noise <1.1 mVrms at 33 GHz bandwidth.

This high sensitivity is critical for being able to make accurate measurements on low amplitude signals. The P7600 Series TriMode probes were designed to deliver superior sensitivity and allow the oscilloscope to directly measure small signals without using a zoom function. Using a zoom function to look at small signals does not change the intrinsic noise floor of the instrument which can make measurements on small signals problematic.

Connectivity

The P7600 Series probes utilize an interchangeable active tip design built around a custom tip interface using high frequency SMPM connectors. The P7600 Series probes feature an Automatic Adapter ID function that recognizes the attached adapter and automatically applies the correct DSP filters that eliminate imperfections in the frequency response all the way to the probe tip. This feature eliminates the risk of manually selecting the wrong tip type and is more efficient for the user.

Coaxial adapters

Coaxial adapters enable the probe to act like a differential input channel for the oscilloscope which effectively doubles the number of differential signals a single oscilloscope can measure simultaneously.

P76CA-292


33 GHz Bandwidth Coaxial Adapter with 2.92 mm (Female) connectors. This adapter is calibrated at the input connectors and is ideal for use with off the shelf or custom cables. Low skew cable pairs should be used to preserve full bandwidth performance.

P76CA-292C


33 GHz Bandwidth Coaxial Adapter with 2.92 mm (Male) connectors and 6" of high performance cable. This adapter is calibrated at the input connectors and is ideal for directly connecting to devices with 2.92 mm or SMA output connectors.

P76CA-SMP


33 GHz Bandwidth Coaxial Adapter with SMP (Female) connectors and 6" of high performance cable. This adapter is calibrated at the input connectors and is ideal for directly connecting to devices with SMP output connectors.

P7500 Series solder tip adapter

This adapter allows the P7630 probe to use existing Tektronix P7500 probe tips. The P7600 Series probe amplifiers have a 50 Ω input. When combined with a P7500 probe tip, the probe turns into a passive Z0 style probe with 450 Ω of differential input impedance. While Z0 probes can typically present a significant DC load to the device under test, the P7600 Series probes will minimize the effect of DC loading through the use of termination voltage adjustment.

P76TA




30 GHz Bandwidth P7500 Tip Adapter. The probe and oscilloscope system will support up to 30 GHz of bandwidth when this adapter is used with the P75PST Performance Solder Tip.

P76CA-BTI292 coax adapter

 

The P76CA-BTI292 coax adapter allows the conversion of the P76TA or P76CA adapters' custom tip interface to a pair of 2.92 mm connectors. Using this adapter, the distance between the circuit under test and the oscilloscope, switching matrix or other equipment can be extended. High bandwidth, low skew cable pairs should be used for this extended reach.

Unique probe filters

The P7600 Series probes contain probe specific S-parameter data. Attaching a P7600 probe to a DSA/DPO70000D oscilloscope transfers this data to the instrument to create unique system DSP filters based on the specific S-parameter data of the oscilloscope and the probe. Creating unique filters based on the specific response of the system is critical as bandwidths increase. At bandwidths of 33 GHz, small variations in the signal path can lead to significant variation in frequency response. These variations are corrected using DSP filtering.
