Description

When performing a module vertical calibration (:CALibrate:SLOT:VERTical) on a TDR module, this command enters the load resistance into the dialog shown below. Enter the actual measured resistance of the load. The default value is 50Ω. The minimum value is 47Ω and the maximum value is 53Ω. The value can be stepped in 10 mΩ increments. Calibrations performed using non-precision loads either fail or result in inaccurate results.

Although FlexDCA does not support TDR mode, you can still use the TDR module's vertical channel.
