Example 1:
→
MEASure:VOLTage:AC? 0.6,(@2)
Send
←
Read <the measured AC-RMS value>
→
Send FETCh:DC? (@2)
←
Read <the measured DC component>
→
Send FETCh:AMPLitude? (@2)
←
Read <the measured amplitude>
Example 2:
→
Send CONFigure:AC
→
Send TRIGger:SOURce BUS
→
Send SENSe:VOLTage:RANGe:OFFSet .25
→
Send INITiate
→
Send TRG
*
→
Send FETCh:AC?
←
Read <the measured AC-RMS voltage>
Note: Because the trigger source is BUS (GPIB), the GET (Group Execute
Trigger) code must be sent after INITiate and before FETCh? to trigger
the acquisition.
Errors:
(1) When a FETCh? query is executed and no valid acquisition data is
available, nor an acquisition pending, execution error -230, "Data corrupt or
stale" is generated. In that case, no result is returned as response to the
FETCh? query.
(2) When a FETCh? query for a characteristic from a TRACe memory element
is received, which does not contain valid acquisition data, execution error
-230, "Data corrupt or stale" is generated.
