VOLTage[:LEVel] <Voltage Level>
Sets the test signal voltage in RMS (root mean square).
Parameters:
<Voltage Level> <numeric>
Sets the value.
MIN | MINimum
Queries the lower limit of the signal level.
MAX | MAXimum
Queries the upper limit of the signal level.
DEF | DEFault
Queries the signal level the instrument sets by default.
Range: 0.01 V to 10 V (depends on measurement settings)
Increment: 0.001 V

11.5 BIAS subsystem
The BIAS subsystem contains the commands for bias configuration.
Example: Bias settings
The example represents the remote control commands for applying either an external
or an internal DC bias level.
// Assign an internally generated voltage level and enable bias.
BIAS:VOLTage[:LEVel] 1
BIAS:CURRent[:LEVel] 0.1
BIAS:STATe 1
// Query an externally applied voltage level and enable bias.
BIAS:EXTernal:MEASure:VOLTage?
// Response: 0.2
BIAS:EXTernal[:VOLTage][:STATe]ON
// Response: 1

To activate the bias, use command BIAS:STATe on page 189.
Parameters:
BiasCurrent Range: 0 to 0.2 A
Increment: 0.001 A
*RST: 0 A
Default unit: A
Example: See Example "Bias settings" on page 188.

BIAS:EXTernal:MEASure:VOLTage?
Queries the value of the externally applied voltage.
Parameters for setting and query:
<voltage> Default unit: V
Example: See Example "Bias settings" on page 188.
Usage: Query only
BIAS:EXTernal[:VOLTage][:STATe] <External Voltage Bias State>
Enables the externally supplied bias voltage.
Parameters:
<External Voltage
Bias State>
1 | 0 | ON | OFF
*RST: OFF
Example: See Example "Bias settings" on page 188.
BIAS:STATe <Bias State>
Enables the internal DC bias.
To set the corresponding bias voltage or current value, use commands BIAS:
CURRent[:LEVel] on page 188, or BIAS:VOLTage[:LEVel] on page 189.
Parameters:
<Bias State> 1 | 0 | ON | OFF
*RST: OFF
Example: See Example "Bias settings" on page 188.
Manual operation: See "[Bias Enable]" on page 75
