Measurement Speed
Selects the speed of the measurement repetitions per second.
Using this speed parameter requires that you have set continuous triggering, see
Chapter 8.1.1, "Measurement mode settings" , on page 67.
"Fast:
≤
15 ms"
Number of measurements:
≈
15 / s.
"Medium:
≤
100 ms"
Number of measurements:
≈
10 / s.
"Slow:
≤
500 ms"
Number of measurements:
≈
1.5 / s.
Remote command:
APERture

Cable Length
Selects the length of the leads to the connected test fixture, i.e. to the DUT.
When connected to a test fixture with leads, the R&S LCX considers the cable losses.
If you have the test fixture connected to the BNC measurement connectors directly,
select 0
m, as there are no cable losses to be compensated. For test adapters with
leads, set the parameter to 1 m accordingly.
Remote command:
CORRection:LENGth
on page 182
Test Signal Type
Selects the parameter for the setting the level of the test signal level.
The setting parameter for the test signal level on the measurement window varies
according to the selection, see
"Level: / [Level]" on page 71.
"Voltage" Enables you to set the signal level in volt.
"Current" Enables you to specify the signal current.
Remote command:
CORRection:LENGth

Voltage Bias
Activates the use of an external voltage bias, if supplied.
Note: Make sure that the external DC voltage source supplies a constant voltage bias
to avoid distortion of the measurement results due to interference.
To set the value, see
Chapter 6.3.2, "External voltage bias" , on page 60.
Remote command:
BIAS:STATe
on page 179
Source Impedance
Selects the output impedance for the measurement.
