Model 2100 6 1/2-Digit Resolution Digital Multimeter User’s Manual Appendix B: Remote Interface Reference

CALCulate:DBM:REFerence {<value>|MINimum|MAXimum}

Set the dBm reference value. Choose from: 50 ~ 8000 ohms.

CALCulate:DBM:REFerence? [MINimum|MAXimium]

Query the dBm reference value.

DATA:FEED RDG_STORE,{"CALCulate"|""}

Selects whether readings taken using the INITiate command are stored in the multimeter's internal

memory (default) or not stored at all. In the default state (DATA:FEED RDG_STORE,"CALC"), up

to 2000 readings are stored in memory when INITiate is executed. The MEASure? And

CONFigure commands automatically select "CALC.” With memory disabled (DATA:FEED

RDG_STORE,""), readings taken using INITiate are not stored. This may be useful with the Min/

Max operation since it allows you to determine an average of the readings without storing the

individual values. An error will be generated if you attempt to transfer readings to the output buffer

using the FETCh? command.

DATA:FEED?

Query the reading memory state. Returns "CALC" or "".

The triggering commands

INITiate

Change the state of the triggering system from the "idle" state to "wait-for-trigger" state. The meter

will start to make measurements when a required triggering condition is met after the INITiate

command is received. Readings are stored in memory until you are ready to read them. Use the

FETCh? command to retrieve your measurements results.

READ?

Change the state of the triggering system from the "idle" state to the "wait-for-trigger" state. The

meter will start to make measurements when a required triggering condition is met after the

READ? command is received. Readings are sent to the output buffer immediately.

TRIGger:SOURce {BUS|IMMediate|EXTernal}

Select a trigger source. The multimeter will accept a software (BUS) trigger, an immediate internal

trigger, or a hardware trigger from the rear-panel EXT TRIG terminal.

TRIGger:SOURce?

Query the trigger source.
