Set DC Bias (DC Bias Function)
If the sweep parameter is set to frequency sweep or oscillator level sweep, the following
GPIB command can be used to apply the dc bias to the DUT in either fixed voltage or
current source mode.
Set in Fixed Voltage Source Mode
Use the following GPIB command to turn on or off the dc bias output. Note that when the
dc bias is turned on from off, the sweep mode is automatically set to hold mode.
• SOUR:VOLT:OFFS:STAT on page 484
Set in Fixed Current Source Mode
Use the following GPIB command to turn on or off the dc bias output. Note that when the
dc bias is turned on from off, the sweep mode is automatically set to hold mode.
• SOUR:CURR:OFFS:STAT on page 465
DC Bias Monitor Function
The following GPIB command can be used to display a dc bias monitor value.
• CALC:BMON on page 291
NOTE The dc bias monitor value displayed on the screen is that of the stimulus at an active
marker position. Therefore, the marker must be turned on and the marker must be set to the
specified stimulus value before the dc bias monitor function can be used.
