322 VT1422A Command Reference Chapter 7
OUTPut
OUTPut:VOLTage:AMPLitude
OUTPut:VOLTage:AMPLitude <amplitude>,(@<ch_list>) sets the excitation
voltage on programmable Strain Bridge Completion SCPs pointed to by <ch_list>
(the VT1511A for example).
Note This command is not used to set output voltage on SCPs like the VT1531A Voltage
Output SCP.
Parameters
Comments • To turn off excitation voltage (when using external voltage source) program
<amplitude> to 0.
• Related Commands: OUTP:VOLT:AMPL?
• *RST Condition: MIN (0) for VT1511A
• Send with VXIplug&play Function: hpe1422_cmd(...)
Usage OUTP:VOLT:AMPL 5,(@116:119)
set excitation voltage for channels 16
through 19
OUTPut:VOLTage:AMPLitude?
OUTPut:VOLTage:AMPLitude? (@<channel>) returns the current setting of
excitation voltage for the channel specified by <channel>. If the channel is not on a
VT1511A SCP, the query will return zero.
Comments • The <channel> parameter must specify a single channel only.
• Returned Value: Numeric, one of 0, 1, 2, 5, or 10 for VT1511A SCP, 3.9 for
non- programmable VT1506A/07A SCPs. Data type is float32.
• Related Commands: OUTP:VOLT:AMPL
• Send with VXIplug&play Function: hpe1422_cmdReal64_Q(...)
Usage OUTP:VOLT:AMPL? (@103)
returns current setting of excitation
voltage for channel 3
