VXi VT1422A 사용자 설명서

[SENSe:]FUNCtion:TEMPerature  <type>,<sub_type>,[<range>,] 
(@<ch_list>) for temperature measurements with thermocouples, 
thermistors or RTDs

[SENSe:]FUNCtion:VOLTage  <range>,(@<ch_list>) for voltage 
measurements

[SENSe:]FUNCtion:CUSTom  <range>,(@<ch_list>) for custom EU 
conversions.

At power-on and after *RST, the default EU Conversion is autorange 
voltage for all 64 channels.

To link channels to the voltage conversion send the 
[SENSe:]FUNCtion:VOLTage [<range>,] (@<ch_list>) command.

•

The <ch_list> parameter specifies which channels to link to the 

voltage EU conversion.

•

The optional <range> parameter can be used to choose a fixed A/D 

range. Valid values are: 0.0625, 0.25, 1, 4, 16, or AUTO. When not 
specified, the module uses auto-range (AUTO).

To set channels 0 through 15 to measure voltage using auto-range, send:

SENS:FUNC:VOLT AUTO,(@100:115)

SENS:FUNC:VOLT AUTO,(@10000:10131)

To set channels 16 and 24 to the 16 volt range and 32 through 47 to the 
0.0625 volt range, send:

SENS:FUNC:VOLT 16,(@116,124)

SENS:FUNC:VOLT .0625,(@132:147)

or send both commands in a single command message:

SENS:FUNC:VOLT 16,(@116,124);VOLT  .0625,(@123:147)

When using manual range in combination with amplifier SCPs, the EU 
conversion will try to return readings which reflect the value of the input 
signal. However, it is up to the user to choose range values that will provide 
good measurement performance (avoiding over-ranges and selecting ranges 
that provide good resolution based on the input signal). In general, 
measurements can be made at full speed using auto-range. Auto-range will 
choose the optimum A/D range for the amplified signal level.
