and Error-Correction
The HP 8753E analyzer has the capability of making calibrations using the method.

measure the “TRL THRU,” connect the “zero length” transmission line between the two
test ports.

make the necessary four measurements, press:
5. measure the “TRL SHORT, connect the short to PORT 1, and press:
6. Connect the short to PORT 2, and press:
7. measure the “TRL LINE,” disconnect the short and connect the TRL line from PORT 1 to
PORT 2.

Note
You should perform the isolation measurement when the highest dynamic range
is desired.
perform the best isolation measurements, you should reduce the system
bandwidth, and/or activate the averaging function.
A poorly measured isolation class can actually degrade the overall
measurement performance. If you are in doubt of the isolation measurement
quality, you should omit the isolation portion of this procedure.
Note
If loads can be connected to both port 1 and port 2 simultaneously, then. the
