How it works

The 34980A routes signals through plug-in switch modules to either an optional internal DMM or to external instruments connected through the analog bus connector on the rear panel. The mainframe provides four 2-wire internal analog buses for signal routing. One bus can be dedicated to the internal DMM while the other three buses can be used for module extensions or additional signal routing between modules.^[1]^[4]

The optional internal DMM can measure 11 types of inputs: temperature with thermocouples, RTDs, or thermistors; DC and AC voltage; 2- and 4-wire resistance; frequency and period; and DC and AC current. Each switch channel can be configured independently for measurement functions, scale factors, and alarm limits. Advanced measurement features such as offset compensation, variable integration time, and delay are selectable on a per-channel basis. The DMM inputs are shielded and optically isolated from the earth-referenced circuitry and computer interface, providing up to 300 V of input isolation.^[1]^[4]
