5.2.2 Reflection Normalization
Reflection normalization is the simplest calibration method used for reflection
coefficient measurements (S11 or S22). Only one standard (SHORT or OPEN) is
measured (See figure 5.7) in the process of this calibration. You can also perform
directivity calibration by measuring a LOAD standard.
Figure 5.7 Reflection normalization
Before starting calibration perform the following settings: select active channel, set the
parameters of the channel (frequency range, IF bandwidth, etc), and select the
calibration kit.
To open reflection normalization submenu, use the
following softkeys:
Calibration > Calibrate > Response (Open) | Response
(Short)
Select the test port to be calibrated using Select Port.
Clicking this softkey you can switch between the test ports
(measured parameters).
Connect an OPEN or a SHORT standard to the test port as
shown in figure 5.7. Perform measurement using Open or
Short softkey respectively.
The instrument status bar will indicate Calibration in
progress... when the measurement is in progress. On
completion of the measurement, a check mark will appear
in the left part of the softkey.
