VXi VT1422A 사용자 설명서

To set channels 0 through 9 to output 30 µA and channels 10 through 19 to 
output 488 µA:

OUTP:CURR 30e-6,(@100:109)

OUTP:CURR 488e-6,(@110:119)

or combine into a single command message:

OUTP:CURR 30e-6,(@100:109);CURR  488e-6,(@110:119)

The OUTPut:CURRent:AMPLitude command is only for programming 
excitation current used in resistance measurement configurations. It is does 
not program output DAC SCPs like the VT1532A.

The VT1511A Strain Bridge Completion SCP has a programmable bridge 
excitation voltage source. The command to control the excitation supply is 
OUTPut:VOLTage:AMPLitude <amplitude>,(@<ch_list>)

•

The <amplitude> parameter can specify 0, 1, 2, 5, or 10 volts for the 

VT1511A’s excitation voltage.

•

The <ch_list> parameter specifies the SCP and bridge channel 

excitation supply that will be programmed. There are four excitation 
supplies in each VT1511A.

To set the excitation supplies for channels 0 through 3 to output 2 volts:

OUTP:VOLT:AMPL 2,(@100:103)

The OUTPut:VOLTage:AMPLitude command is only for programming 
excitation voltage used measurement configurations. It is does not program 
output DAC SCPs like the VT1531A.

This step links each of the module’s channels to a specific measurement type. 
For analog input channels this "tells" the on-board control processor which 
EU conversion to apply to the value read on any channel. The processor is 
creating a list of conversion types vs. channel numbers. The commands for 
linking EU conversion to channels are:

[SENSe:]FUNCtion:RESistance  <excite_current>,[<range>,] 
(@<ch_list>) for resistance measurements

(@<ch_list>) for strain bridge measurements
