Hewlett Packard 70800B MSIB Cable

The 70800B is a 1.0 meter long Modular System Interface Bus (MSIB) cable, intended for connecting the HP/Agilent/Keysight 70000-series modular instruments—specifically, linking the mainframe (70001A) and display (70004A) over the MSIB bus.

It features controlled-impedance twisted-pair wiring, which is crucial for signal integrity and preventing communication issues—standard DB-37 cables without such designs won’t work properly.
