Comments

If the channels specified are not on a Frequency/Totalize SCP, an error will be generated.

Returned Value: returns the numeric pulse width. The type is float32.

SOURce:RPULse:POSition[:ANGLe]

SOURce:RPULse:POSition[:ANGLe] <degrees>,(@<ch_list>) sets the angular position of the rotational output pulse before the INIT command that starts algorithm execution. With the pulse position thus fixed, the pulse width (in angle or time depending on how SOUR:RPUL:VARType is set) will be controlled by the algorithm.

Comments Channels in <ch_list> must be referenced in a SOUR:FUNC:RPUL command before the next INIT command. Related error messages: 3113, "Channel specified is not in same SCP as reference channel."

3114, "First channel in SCP can not be used in RPULse output channel list."

<degrees> has a resolution of 1 degree. The pulse is positioned at <degrees> modulo 360.
