Keysight M8070A Programming Guide 441
SCPI Command Reference 5
[,<overwrite-flag>]: ON | OFF | 0 | 1
Optional flag is a boolean parameter which specifies if an existing pattern
file should be overwritten or not.
Description The currently uploaded pattern is stored into the specified file on the hard
disk.
This SCPI is applicable for M8041A and M8051A.
Example The following example saves a compare and capture measurement with
the measurement name identifier called ‘MyMeasurement’:
:PLUGin:CCAPture:SAVE "MyMeasurement", "M1.Datain1",
"current:CapData"
:PLUGin:CCAPture:SAVE "MyMeasurement", "M1.Datain1",
"current:CapData",1
:PLUGin:CCAPture:TRIGger:IMMediate[:ONCE]
Syntax :PLUGin:CCAPture:TRIGger:IMMediate[:ONCE]
Input
Parameters
‘identifier’: Specify the measurement name.
'location' 'M*.DataIn1' or 'M*.DataIn2'
Description This command simulates a stop event. Compare and capture is stopped
and the recorded data is uploaded into the measurement.
This SCPI is applicable for M8041A and M8051A.
Example PLUGin:CCAPture:TRIGger:IMMediate:ONCE ‘MyMeasurement’
:PLUGin:CCAPture:SHOW:BIT[:PATTern][:VIEW][?]
Syntax :PLUGin:CCAPture:SHOW:BIT:PATTern:VIEW 'identifier', ‘Mode’
:PLUGin:CCAPture:SHOW:BIT:PATTern:VIEW? 'identifier'
Input
Parameters
‘identifier’: Specify the measurement name.
‘Mode’: BIN|HEX
Return Range BIN|HEX
Description This command selects the bit pattern view mode viz. BIN|HEX.
This SCPI is applicable for M8041A and M8051A.
Example :PLUGin:CCAPture:SHOW:BIT:PATTern:VIEW 'MyMeasurement', BIN
