Keysight 34980A Mainframe User’s Guide
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.
NOTE
You can use the MEASure? command in one of two forms depending on which
measurement mode you wish to use.
– If you omit the optional <ch_list> parameter, the MEASure? command applies
to the internal DMM.
– If you specify a <ch_list>, the MEASure? command performs a “temporary”
scan of the specified channels (independent of the present scan list).
