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 Figure 3-22, to establish a reference for
flatness.
2. A cable is inserted between the power sensor and the test port, as shown in Figure 3-23, to establish a
reference for the cable.
3. The same cable is connected between the two test ports, as shown in Figure 3-24, and a 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 USB drive) 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.
Equipment Used for the Receiver Calibration Adjustment
Procedure
1. Connect the equipment as shown in Figure 3-22. Connect a GPIB cable between the network analyzer
and the power meter.
2. On the System menu, point to Service, Adjustments, and then click Receiver Calibration.
3. Ensure the GPIB settings are correct.
4. Click Calibrate, and then follow the instructions as they are displayed.
