Calibrating for Increased Measurement Accuracy
Frequency Response and Isolation Error Corrections
7. Make a "thru" connection between the points where you will connect your device under
test.
Include any adapters that you will have in the device measurement. That is,
NOTE
connect the standard device to the particular connector where you will
connect your device under test.
8. To measure the standard, when the displayed trace has settled, press:
THRU
The analyzer displays WAIT - MEASURING CAL STANDARD during the standard
measurement. The analyzer underlines the
calibration standard, and computes the error coefficients.
9. Connect impedance-matched loads to PORT 1 and PORT 2, as shown in
Include the adapters that you would include for your device measurement.

If you will be measuring highly reflective devices, such as filters, use the test
