For details about aperture step width, refer to descriptions in "Aperture Step
Width" for S11.
Align
In full 2-port calibration, the calibration data are measured by connecting "Through"
to two ports.
This calibration effectively eliminates the frequency response reflection tracking error,
directivity error, and source match error from the test set in a reflection test using
that port.
1. Through
Connect "Through" to the selected test port. Press or tap Through to start
calibration.
2. Abort
During calibration, you can press or tap Abort to suspend calibration.
3. Done
After completing calibration, press or tap Done to complete calibration. Then,
the calibration results are saved.
Remarks:
⚫ Before calibration, set the required sweep frequency range first and select the
specified calibration kit.
⚫ The calibration is only valid for the S21 measurement item. When switching to
S11 or DTF, you need to recalibrate.
Clear
Clears the calibration data acquired for the current measurement.
Port Extension
Extends the calibrated plane by setting the delay and loss of the test signal resulting
from the electrical length and compensation fixture of the connector. In this way, you
do not need to perform extra calibration any more.
Port Extension
Enables or disables the port extension function. By default, it is disabled.
Only when the port extension function is enabled, can you set the parameters for
port extension.
Port 1 Delay
Sets the delay time for Port 1 extension.
