Channel must specify a single channel.

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

•Related Commands: SOUR:PULM[:STATe], SOUR:PULS:POLarity, SOUR:PULS:PERiod, SOUR:FUNC[:SHAPe]:SQUare

Usage The variable frequency control for this channel is provided by the algorithm language. When the algorithm executes an assignment statement to this channel, the value assigned will be the frequency setting. For example:

O143 = 2000 /* set channel 43 to 2KHz */

SOURce:FM:STATe?

SOURce:FM:STATe? (@<channel>) returns the frequency modulated mode state for a PULSe channel.

•If the channel specified is not on a Frequency/Totalize SCP, an error will be generated.

•Returned Value: returns 1 (ON) or 0 (OFF). The type is uint16.
