54754A

Keysight Technologies (Agilent HP)TDR, Cable Testers

The Keysight (Agilent) 54754A is a high-performance 18-GHz differential TDR/TDT sampling module designed for use with Infiniium DCA, DCA-J, and legacy Agilent digitizing oscilloscope mainframes. It features two channels with built-in TDR step generators that can operate independently or in tandem for differential or common-mode stimulus-response measurements. When the TDR generators are disabled, the module functions as a high-bandwidth vertical acquisition system.
