DF254A grounded differential probe is a passive probe suitable for TDR (Time Domain Reflectometry) applications.

The ergonomic case design providing best ratio of width and thickness. The perfect matched ratio maintaining long-term operation comfort. An arrow sign at the front-end depicts the signal pins location and orientation.

Base on patented procedures, all DF254A were adjusted for near perfect impedance match to TDR equipments such as Keysight 86100D with 54754A TDR/TDT module. This can minimize mismatch effect and hence the better performance can be achieved.

The trace waveform at right represents the typical performance of connecting a probe to TDR modules.
