Comments
·
This command is coupled with the SOURce:PULM:STATE command. If the FM
state is ON then the PULM state is OFF. If the PULM state is ON then the FM
state is OFF. If both the FM and the PULM states are OFF then the PULSe
channel is in the single pulse mode.
·
If the channels specified are not on a Frequency/Totalize SCP, an error will be
generated.
·
Use SOURce:FUNCtion[:SHAPe]:SQUare to set FM pulse train to 50% duty
cycle. Use SOURce:PULSe:PERiod to set the period
·
*RST Condition: SOUR:FM:STATE OFF, SOUR:PULM:STATE OFF,
SENS:FUNC:COND and INP:POL for all digital SCP channels
