SOURce
•
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 2 kHz */
•
Send with VXIplug&play Function: hpe1422_cmd(...)
Usage SOUR:PULS:WIDTH 2.50E-3,(@143)
set fixed pulse width of 2.5 ms on
channel 43
SOURce:PULSe:WIDTh?
SOURce:PULSe:WIDTh? (@<ch_list>) returns the fixed pulse width value on a
frequency modulated pulse channel.
Parameters
Comments •
The <channel> parameter must specify a single channel.
•
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.
•
Send with VXIplug&play Function: hpe1422_cmdReal64_Q(...)
SOURce:VOLTage[:AMPLitude]
SOURce:VOLTage[:AMPLitude] <-offset_v>,(@<ch_list>) can be used to
reduce bridge offset voltage present at the dynamic strain "Buffered Output"
channel connectors.
Parameters
Comments •
If the channels specified are not on a VT1529A/B, an error will be generated.
•
*RST Condition: SOUR:VOLT 0,(@ <all VT1529A/B channels>)
