Receiver Calibration 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
reference for flatness.
2. A cable is inserted between the power sensor and the test port, as shown in
to establish a reference for the cable.
3. The same cable is connected between the two test ports, as shown in
signal from Port 1 is used to adjust the "B" 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 hard disk
drive (where xx is a 1 or 2 digit number). The data are used in subsequent measurements.
If the hard disk 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.
These files can be recreated by performing another receiver calibration adjustment.
