4 - 56 COMMAND REFERENCE
Example 1:
Send
→ MEASure:VOLTage:AC? 0.6,(@2) Measures AC- RMS on
channel 2, expected
voltage 600 mV.
Read
← <the measured AC-RMS value>
Send
→ FETCh:DC? (@2) Fetches the DC
component.
Read
← <the measured DC component>
Send
→ FETCh:AMPLitude? (@2) Fetches the waveform
amplitude.
Read
← <the measured amplitude>
Example 2:
Send
→ CONFigure:AC Configures for AC-RMS.
Send
→ TRIGger:SOURce BUS Trigger source GPIB.
Send
→ SENSe:VOLTage:RANGe:OFFSet .25 250 millivolt offset.
Send
→ INITiate Initiates trigger system.
Send
→
*
TRG Triggers (GET) via GPIB.
Send
→ FETCh:AC? Fetches AC-RMS value.
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.
