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.
