Agilent/Keysight Y1137A

The Keysight Y1137A is a shielded cable assembly engineered to connect the Keysight 34980A multifunction switch/measure mainframe to its associated modules. This twisted-pair cable with outer shield minimizes electromagnetic interference, maintaining signal integrity across precision measurement applications. The assembly terminates in a 78-pin D-sub male connector on one end and a 78-pin D-sub female connector on the other, providing reliable interconnection in complex test configurations.

Rated for DC 300V at up to 1A maximum current, the cable spans 1.5 meters in length, accommodating typical rack and benchtop setups. Note that certain modules may require two cables for complete connection.
