Matched Adapters - Agilent Technologies 8753ET User Manual

Matched Adapters

With this method, you use two precision matched adapters which are "equal." To be equal,
the adapters must have the same match, Z
adapters in most Agilent calibration kits have matched electrical length, even if the
physical lengths appear different.

To use this method, refer to
1. Perform a transmission calibration using the first adapter.
2. Remove adapter A, and place adapter B on port 2. Adapter B becomes the effective test
port.
3. Perform a reflection calibration.
4. Measure the test device with adapter B in place.
The errors remaining after calibration with this method are equal to the differences
between the two adapters that are used.
