Keysight M8070A Programming Guide 349
SCPI Command Reference 5
:PLUGin:OLEVel:FETCh:DATA?
Syntax :PLUGin:OLEVel:FETCh:DATA? ‘identifier’[,‘Location’]
Input
Parameters
‘identifier’: Specify the measurement name.
[,‘Location’]: ‘M*.DataIn1’ or ‘M*.DataIn2’ (optional).
Description Return the raw data of the output level measurement.
This SCPI is applicable for M8041A, M8051A and M8062A.
Example A measurement run on location e.g 'M1.DataIn1' would return following
results.
:PLUG:OLEV:FETC:DATA? ‘MyMeasurement’,'M1.DataIn1'
Return: ("M1.DataIn1", ...
The first item in that comma separated list is the name of the location here
"M1.DataIn1",the next values are TimeStamp, ComparedOnes,
ComparedZeroes, ErroredOnes, ErroredZeroes and SampleThreshold and
these 6 values will be repeated.
If the 'Location' is omitted and the measurement runs on multiple locations
the response contains all results of current location.
(("M1.DataIn1", ...),( "M1.DataIn2", ...))
:PLUGin:OLEVel:FETCh:FREQuency?
Syntax :PLUGin:OLEVel:FETCh:FREQuency? ‘identifier’ [,‘Location’]
Input
Parameters
‘identifier’: Specify the measurement name.
[,‘Location’]: ‘M*.DataIn1’ or ‘M*.DataIn2’ (optional).
Description This command fetches frequency set for the whole module. It also prefixes
the acquisition location.
This SCPI is applicable for M8041A, M8051A and M8062A.
Example :plugin:olev:fetch:frequency? "MyMeasurement"
