Connection to the 34980A Analog Buses
This module does not internally connect to the 34980A mainframe’s four 2-wire
(HI, LO) 300V-rated Analog Buses.
– ABUS1 (MEAS) and ABUS2 (SENSE) connect to the internal DMM.
– ABUS3 and ABUS4 are for signal-routing only, and do not connect to the
DMM.
You can connect from a row/column crosspoint directly to the external 9-pin
Analog Bus connector located on the 34980A’s rear panel (see connector pinout
below).
See the “Electrical Operating Conditions” and “Analog Buses” sections of the
34980A Mainframe User’s Guide for complete instructions and safety precautions
for accessing the Analog Buses.
