Please also refer to the documentation supplied with the
patchcord.
a For the user calibration select an electrical calibration as
made according to the procedure given in “Electrical
calibration for single-ended measurements” on page 75.
This calibration must have the same network analyzer
settings as you are using to measure your DUT.
This will only be used for the “user calibration”
measurements. Afterwards the LCA returns to the
original electrical calibration for the DUT measurements.
The currently used calibration is preselected.
b Select “Reduce IFBW for user calibration measurement” to
reduce noise on the user calibration data. The default
bandwidth reduction factor is set in the file
LCAConfig.xml.
c Click to proceed .
