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.
Manual operation: See "Current Bias: / [Bias Level]" on page 75
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
See "Voltage Bias" on page 81
BIAS:VOLTage[:LEVel] <Bias Voltage Level>
Sets the internal DC bias voltage value.
To enable the bias, use command BIAS:STATe on page 189.

Example: Performing open/short/load correction
The example represents the remote control commands to configure the correction set-
tings.
// Configure the corrections settings:
// set the cable length between the DUT and the instrument
CORRection:LENGth 1 // the test leads are of 1m length
// ***************************
// Perform open correction on all frequencies
CORRection:OPEN:STATe 1
CORRection:OPEN[:EXECute]
// query if operation is complete and successfull
*OPC?
SYSTem:ERRor?
// ***************************
// Perform open correction on the current working point
CORRection:SPOT:OPEN[:EXECute]
// ***************************
// Perform short correction on all frequencies
CORRection:SHORt:STATe 1
CORRection:SHORt[:EXECute]
// Perform short correction on the current working point
CORRection:SPOT:SHORt[:EXECute]
// ***************************
// Save and restore a correction data set
// of a full or short correction
// !! not provided for spot and load correction data
CORRection:STORage:Save 2
// saves the data in memory slot 2
CORRection:STORage:RESTore 2
// recalls the correction data in memory slot 2
// ***************************
// Perform load correction on all frequencies
CORRection:LOAD:STATe 1
// Configure the expected value of the load
CORRection:SPOT:LOAD:STANdard 15,20
// Perform load correction at the current working point
