The Picotest P2103A probe is a 100 ohm input impedance differential transmission line 'browser' probe for TDR/TDT applications. This precision probe supports a variety of measurements.
To characterize a differential pair, the TDR must drive a differential signal and measure the response as the reflected differential signal. This requires two channels to be connected to the same end of the differential pair, and have the equivalent of two, simultaneous stimulus - either launching a differential signal or launching a common signal into the device under test (DUT). This is done with a differential TDR.
The P2103A is a referred to as a 'browser' probe for its ability to easily and quickly be moved from point-to-point/rail-to-rail simply by re-seating the probe points. The probe achieves a very low inductance at the tip to mitigate space constraints on a dense PCB, while eliminating the need to add additional SMA connections or other test points necessary for impedance measurements. It is especially useful when there are multiple trace pairs to assess and there is no time for PCB iterations to provide test point implementations for each. Repeated measurements are simplified because connection is by simply touching the tips to existing traces. The fixed spacing between signal pins provides for highly reliable and repeatable data measurements. The rugged, ergonomic design allows easy TDR measurements by hand. The slim body with the extended tips provides good visibility of the target.
The P2103A comes with two fixed pin pitches (50 and 100 mil spacing with 1X attenuation), though customized pitches are available.
NOTE: The probe is compatible with all TDR/TDT applications and measurements; however, only differential mode measurements are supported when using the J2154A TDR.
Engineers working on high-speed differential electrical channels can analyze where the DUT causes reflections that unfavorably affect the signal integrity (SI) of their designs. Multiple P2103A probes can be used with 4, 6, and 8 port TDR test setups.
