[SENSe:]VOLTage:AC:RANGe
[SENSe:]VOLTage:AC:RANGe
[SENSe:]VOLTage:DC:RANGe
Syntax
[SENSe:]VOLTage:AC:RANGe {<range>|MIN|MAX}[,(@<ch_list>)]
[SENSe:]VOLTage:AC:RANGe? [{(@<ch_list>)|MIN|MAX}]
[SENSe:]VOLTage:DC:RANGe {<range>|MIN|MAX}[,(@<ch_list>)]
[SENSe:]VOLTage:DC:RANGe? [{(@<ch_list>)|MIN|MAX}]
Description
These commands selects the measurement range for AC and DC voltage measurements on the specified channels.
Used With:
- 34901A 20 Channel Multiplexer (2/4-wire) Module
- 34902A 16 Channel Multiplexer (2/4-wire) Module
- 34908A 40 Channel Single-Ended Multiplexer Module
Parameters
Name Type Range of Values Default Value <range> Discrete Desired range in volts:
100 mV (MIN)
1 V
10 V
100 V
300 V (MAX)This is a required parameter. <ch_list> Channel List One or more channels, as shown:
(@310) - channel 10 on the module in slot 300.
(@305:310) - channels 05 through 10 on the module in slot 300.
(@202:207,209,302:308) - channels 02 through 07 and 09 on the module in slot 200 and channels 02 through 08 on the module in slot 300.
If you omit the optional <ch_list> parameter, this command applies to the currently defined scan list.
Remarks
- Selecting a discrete range will disable autoranging on the specified channels (see [SENSe:]VOLTage:AC:RANGe:AUTO command).
- The CONFigure and MEASure? commands automatically enable autoranging if the first parameter is AUTO, DEF or omitted.
- If the input signal is greater than can be measured on the selected range (manual ranging), the instrument gives an overload indication: "±OVLD" from the front panel or "±9.9E+37" from the remote interface.
- The instrument enables autoranging after a Factory Reset (*RST command). An Instrument Preset (SYSTem:PRESet command) or Card Reset (SYSTem:CPON command) does not change the setting.
Return Format
The query returns the range in the form "+1.00000000E+01" for each channel specified. Multiple responses are separated by commas.
Examples
In the following examples, you can substitute the node name AC for DC.
The following command selects the 10 volt range on channels 03 and 13 in slot 100.
VOLT:DC:RANG 10,(@103,113)
The following query returns the range selected on channels 03 and 13 in slot 100.
VOLT:DC:RANG? (@103,113)
Typical Response: +1.00000000E+01,+1.00000000E+01
