[SENSe:]FREQuency:VOLTage:RANGe
Syntax
[SENSe:]FREQuency:VOLTage:RANGe {<voltage_range>|AUTO|MIN|MAX|DEF} [, (@<ch_list>)]
[SENSe:]FREQuency:VOLTage:RANGe? [{(@<ch_list>)|MIN|MAX}]
Description
This command selects the voltage range for frequency measurements on the specified channels. If you omit the optional <ch_list> parameter, this command applies to the internal DMM, independent of any channels or a scan list.
Used With:
34921A through 34925A Multiplexer Modules
Parameters
|
Name |
Type |
Range of Values |
Default Value |
|
<voltage_range> |
Discrete |
Desired range in volts: 100 mV (MIN) |
This is a required parameter |
|
<ch_list> |
Numeric |
One or more channels in the form (@sccc). |
If <ch_list> is omitted, this command applies to the internal DMM. |
Remarks
If you omit the optional <ch_list> parameter, the configuration applies to the internal DMM, independent of any channels or a scan list (any existing scan list is not redefined). An error is generated if the internal DMM is not installed or is disabled.
Selecting a discrete range will disable autoranging on the specified channels.
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.
Since frequency and period are related functions, changing a measurement parameter for one function will also change the corresponding parameter for the other function (see [SENSe:]PERiod:VOLTage:RANGe command).
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 command returns the voltage range in the form "+1.00000000E+01" for each channel specified. Multiple responses are separated by commas.
Examples
The following command selects the 10 volt range for frequency measurements on channels 3 and 13 in slot 1.
FREQ:VOLT:RANG 10,(@1003,1013)
The following query returns the voltage range selected on channels 3 and 13 in slot 1.
FREQ:VOLT:RANG? (@1003,1013)
Typical Response: +1.00000000E+01,+1.00000000E+01
