c) Confirm you selection.
d) Repeat the steps to select the second parameters, e.g. select "Cp-D" (parallel
capacitance, dissipation factor).
6. To set the voltage bias value:
a) Press the [Bias Level] key.
b) Enter a voltage value using the keypad on the screen.
7. Confirm with
.
8. To select the external voltage bias:
a) Press the [settings] key.
b) Select the "Measurement" tab.
c) Activate "External Voltage Bias" with
.
9. Press the [home] key to return to the measurement window.
10. Set up the measurement of the capacitance as described, e.g. in
11. To activate the voltage bias, press the [Bias Enable] key.
The lighting [Bias Enable] key indicates that bias is active.

Current bias
Option: R&S
LCX-K108
When measuring inductances, it is often necessary to superimpose a current bias on
the test signal. You can set an internal current bias from 0
mA to 200
mA (DC), with a
resolution of 1
mA. An external current bias is not supported.
Discharging a current bias before power off
1.
NOTICE!
Risk of instrument damage caused by overvoltage. When you power off
the instrument with the mains power switch, make sure that the bias current is fully
discharged.
When activated, deactivate the bias by pressing [Bias Enable] key.
A progress bar indicates that the discharging process is running.
2. Wait until the process has finished.
Setting a current bias
To bias an inductive component sample:
1. To select the inductance measurement (DUT component type), press the [L] key.
2. Configure the test signal.
3. To select the parameters for measurement results display:
