You are ready to measure now, but remember, after changing cables, connectors or
frequency range you'll have to renew the calibration.
2-port calibration (OSLT)
If you are performing a 2-port measurement, you need to do an OSL calibration on two
ports and a through calibration between the ports. An Isolation calibration is also required.
Normally a Calkit has one termination of each kind, so there are 8 calibration steps. The
MegiQ UFL tools have a dual calibration kit so that calibration steps can be combined.
This reduces the calibration to 4 steps.
Here we describe the calibration procedure with a dual calibration kit.
Instrument set-up
•
Select the kind of measurement (2-port), frequency range, generator power, etc.
•
Select the tab
Calibration
and set up the
port configuration
.
•
Since you can use two terminations at the time, check the
Dual Calkit
option.
•
For each calibration step the list shows which two connections must be made and to
which calibration element(s).
