<measurement pair>
Selects the measurement parameter pairs.
Depending on the type of component sample, the R&S LCX adjusts the list of parame-
ters automatically.
Remote command:
FUNCtion:IMPedance[:TYPE][:PRIMary] on page 212
FUNCtion:IMPedance:TYPE:SECondary on page 213
<measurement accuracy>
The test signal monitor indicates the accuracy of the recent measurement.
Remote command:
FETCh:ACCuracy? on page 206
8.2.2 Configuring the main view
Selecting the parameters
To select the measurement parameters:
1. At the front panel, press the [home] key.
2. Select the parameter pair softkey in the upper left corner of the screen, to open the
selection editor.
3. Select the corresponding measurement pair.
4. Confirm the selection.
5. Select the second measurement pair accordingly.
The R&S LCX displays the selected parameter pairs in the numeric view.
8.3 Measurement functions
The hardkeys provided in the function panel at the front select the measurement com-
ponent type.

8.4 Test signal functions
In this context referred to as test signal parameters, these parameters consider all set-
tings the test signal is composed of. As the core parameters of a measurement, the
R&S LCX provides the access to these settings directly on the screen, and the settings
and function keys.
8.4.1 Test signal settings
With the "Settings" functions, you can define the main characteristics of the test signal.
Access:
1. For accessing the core parameters frequency, level, impedance range and bias,
you have the following options:
● Select the softkey of the corresponding parameter on the screen, e.g. "Fre-
quency:".
● Press the hardkey of the corresponding parameter at the front panel, e.g.,
[Freq.].
On-screen keypads open providing the corresponding entry fields for setting the
value and the unit of the selected parameter.
2. Enter the value and unit accordingly.
3.

.
The required remote commands are described in:
● Section 11.4, "Test signal commands", on page 185
● Section 11.11, "FUNCtion subsystem", on page 209
● Section 11.5, "BIAS subsystem", on page 188

Frequency: / [Freq.]
Sets the test signal frequency.
Remote command:
FREQuency[:CW] on page 187

Sets level of the AC test signal.
To select the parameter for the level setting, see "Test Signal Type" on page 80.
See "About measurement parameters" on page 76.

"Voltage Level"
Sets the signal voltage.
"Current Level"
Sets the signal current.
Remote command:
VOLTage[:LEVel] on page 188
CURRent[:LEVel] on page 187
Range: / [Range]
Selects the measurement range.
Remote command:
FUNCtion:IMPedance:RANGe:AUTO on page 211
FUNCtion:IMPedance:RANGe[:VALue] on page 211
Current Bias: / [Bias Level]
Sets the internal the current preload.
Remote command:
BIAS:CURRent[:LEVel] on page 188
Voltage Bias: / [Bias Level]
Sets the value of the internal voltage preload.
Remote command:
BIAS:VOLTage[:LEVel] on page 189
[Comp.]
Accesses the "Open/Short/Load Correction" dialog, see Section 8.6.1, "Measurement
parameter settings", on page 78.
[Bias Enable]
Enables the internal voltage or current bias.
Remote command:
BIAS:STATe on page 189
8.5 Measurement control functions
With the measurement control hardkeys at the front panel, you can control a running
measurement.
Access:
► Press the corresponding key ([Auto], [Hold] or [Trig.]) at the front panel.
Repeated pressing the [Hold] key turns the function on and off (toggle). The [Auto]
and the [Trig.] keys trigger the corresponding event.
The required remote commands are described in Section 11.11, "FUNCtion subsys-
tem", on page 209.
