Adapter Removal Mathematics
First create the Port 1 calibration set by performing the TRL
1
the adapter connected to Port 2 during the entire
procedure. Save the calibration in Cal Set 1.
Next create the Port 2 calibration set by performing the
TRL 2-Port calibration between Port 2 and the adapter.
Keep the adapter connected to Port 1 during the entire
procedure. Save the calibration in Cal Set 2.
The Adapter Removal function mathematically combines
the Port 1 cal set with the Port 2 cal set to produce a third
cal set having the effects of the adapter removed. The
resulting cal set is as if Port 1 and Port 2 could be connected
together.
When the two calibrations have been saved, proceed with
the adapter removal sequence as follows:
Press:

ADAPTER REMOVAL
Press CAL SET for PORT 1, then CAL SET 1.
CAL SET for PORT 2, then CAL SET 2.
Press
Press ADAPTER 3.5 mm C.l. This specifies the
calibration kit that includes the length specification for the
precision adapter.
Press MODIFY & SAVE, then CAL SET 3.
The new calibration set is computed and stored. 2-Port
correction is turned on.
Now remove the third adapter and connect the device under
test.
The display should now show an accurate S-parameter
measurement of the device.
