Analog Buses - Agilent Technologies Switch/Measure User Manual

Analog Buses

The 34980A provides four 2- wire internal Analog Buses for easier signal
routing. You can route your measurements directly to the internal DMM
using the 34980A multiplexer and matrix modules, or you can connect to
external signals via the Analog Bus connector located on the instrument's
rear panel (see connector pinout below). Since four 2- wire buses are
provided, you can dedicate one bus for use with the internal DMM and
use the other three buses for module extensions or additional signal
routing between modules.
