a) Press the [Bias Level] key.
b) Enter, e.g. 5
V using the keypad on the screen.
5. Confirm with
.
6. Set up the measurement of the capacitance as described, e.g. in
7. To activate the voltage bias, press the [Bias Enable] key.
The lighting [Bias Enable] key indicates that bias is active.
Deactivating current bias
To turn off current bias:
1. Press the [Bias Enable] key.
The unlit [Bias Enable] key indicates that current bias is deactivated.
2. Remove the component sample.

External voltage bias
Option: R&S
LCX-K108
The read-back voltage indicated on the "GUI" relies on the external power supply that
must be activated. If the power supply output is deactivated or the connection is open,
both, the test signal voltage monitor and the external bias voltage monitor can be inac-
curate.
Setting an external voltage bias
To bias a capacitive component sample with a DC voltage supplied by a power supply
instrument:
1.
NOTICE!
Check all cables to make sure that they are not damaged.
Connect the safety sockets of the power supply with the cables of the same color
to the corresponding External Voltage Bias at the
.
2.
NOTICE!
External BIAS requires constant voltage. Before applying the voltage,
make sure that you have set the constant voltage mode in the supplying instru-
ment. Refer to the user manual of the power supply.
Set the output voltage of the supplying instrument to constant voltage mode.
3. On the R&S
LCX, select the capacitance measurement with the [C] key.
4. Configure the test signal.
5. To select the parameters for measurement results display:
a) Select the measurement pair softkey in the upper left corner, to open the selec-
tion editor.
b) Select the parameters "Cp-Rp" (parallel capacitance, parallel resistance).
