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 •The <channel> parameter 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: hpe1422_cmdInt16_Q(...)

SOURce:FUNCtion[:SHAPe]:CONDition

SOURce:FUNCtion[:SHAPe]:CONDition (@<ch_list>) sets the SOURce function
to output digital patterns to bits in <ch_list>.
Parameters

Comments •The VT1533A SCP sources 8 digital bits on the channel specified by this

command. The VT1534A SCP can source 1 digital bit on each of the channels
specified by this command.
