64 Agilent E1538A Enhanced Frequency/Totalize/PWM SCP
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
• Send with VXIplug&play Function: hpe14XX_cmd(...)
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.
Parameters
Comments • Channel must specify a single 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.
• Send with VXIplug&play Function: hpe14XX_cmdInt16_Q(...)
