Overview
In 1-port calibration, calibration data are measured by connecting an OPEN
standard, a SHORT standard, and a LOAD standard to the desired test
port. This calibration effectively eliminates the frequency response
reflection tracking error, directivity error, and source match error from the
test setup in a reflection test using that port.
1-Port error model (1-port calibration)
1. System Z0 should be changed to 1 ohm before calibration when
using waveguide calibration kit and measuring waveguide
devices.
Procedure
1. Press Channel Next/Channel Prev keys to select the channel for which
you want to perform the calibration.
2. Press Cal key.
3. Click Calibrate > 1-Port Cal > Select Port.
4. Select a test port (and corresponding S parameter) on which 1-port
calibration will be performed.
5. Connect an OPEN calibration standard to the selected test port
(connector to which the DUT is to be connected).
6. Click Open to start the calibration measurement.
o If you select the calibration kit which has different
calibration definitions for each gender, (m) and (f) in the
name (label) of the standard displayed in the softkey
indicate male (m) and female (f) for the analyzer's
connector, respectively.
