Communicating with the 34980A over USB

Communicating with the 34980A over GPIB

Analog Bus Connectivity. Normally, designated ABus connected on any module in mainframe. During scan, if ABus 1 and ABus 2 are indicated, they will be used at some point during the scan

An error has been generated and is in the error queue

Remote. Running a program puts the display into “remote” and disables the front panel keys. Pressing the LOCAL button takes you out of “remote” mode and enables the front panel keys.

ABus safety interlock. Terminal block or cables have been removed from the D-sub connector of a module. For more information, see page 96 and page 138.

Waiting for external or manual trigger during scans

Over-temperature condition. One or more general purpose (34937A/34938A) modules have reached their over-temperature limits.

Additional functionality to be implemented

Additional functionality to be implemented

Scaling enabled on channel. This appears on display after you select scaling function via front panel or remote interface

4-wire measurement specified on channel. This appears on display after you select the 4-wire function via the front panel or remote interface.

Offset Compensation specified on channel. This appears on display after you have selected the offset compensation function via the front panel or remote interface.

Measurement is in progress
