VXI VT1538A user manual SOURcePULMSTATe?, SOURcePULSePERiod, Parameters

SOURce:PULM:STATe?

SOURce:PULM[:STATe]? (@<channel>) returns the pulse width modulated mode state for the PULSe channel in <channel>.

Parameters

Parameter	Parameter	Range of	Default
Name	Type	Values	Units
channel	string	100 - 163	none

Comments Channel must specify a single channel.

•Returned Value: returns 1 (on) or 0 (off). The type is int16.

•Send with VXIplug&play Function: hpe14XX_cmdInt32_Q(...)

SOURce:PULSe:PERiod

SOURce:PULSe:PERiod <period>,(@<ch_list>) sets the fixed pulse period value on a pulse width modulated pulse channel. This sets the frequency (1/period) of the pulse-width-modulated pulse train.

Parameters

Parameter	Parameter	Range of	Default
Name	Type	Values	Units
period	numeric (float32)	25E-6 to 7.8125E-3	seconds
		(resolution 0.238μsec)
ch_list	string	100 - 163	none

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

•*RST Condition: SOUR:FM:STATE OFF and SOUR:PULM:STATE OFF

•Related Commands: SOUR:PULM:STATE, SOUR:PULS:POLarity

•The variable pulse-width 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 pulse-width setting. For example:

O140 = .0025 /* set channel 43 pulse-width to 2.5 msec */
