IF Gain Adjustment

The IF gain adjustment is used to adjust the IF gain of the network analyzer.
Procedure
1. Press UTILITY
click IF Gain Adjustment.
2. Follow the instructions and prompts as they are displayed.

Receiver Characterization

This characterizes the receivers in your analyzer.
Procedure
1. Press UTILITY
click Receiver Characterization.
2. Follow the instructions and prompts as they are displayed.

Receiver Adjustment

The receiver calibration is used to adjust the network analyzer receivers for a
flat response across its full frequency range:
1. A power meter/sensor is connected to Port 1, as shown in
establish a reference for flatness.
2. A cable is inserted between the power sensor and the test port, as shown
in Figure
3. The same cable is connected between test port 1 and test port 2, as
shown in
receiver at Port 2.
The adjustment is repeated using a signal from Port 2 to adjust the "A"
receiver at Port 1.
Data obtained during this adjustment are stored in the mxcalfile_pxx files on
the solid state drive. The data are used in subsequent measurements.
If the solid state drive is replaced, these mxcalfile_pxx files will be lost.
Therefore, they should be backed up (saved on a floppy disk) so that they can
be restored. If using multiple disk drives (e.g. classified and general usage),
then these files must be replaced on each individual disk drive.
These files can be recreated by performing another receiver calibration
adjustment.
