Source Adjustment
The source calibration is used to adjust your network analyzer for a flat source
power across its full frequency range. There are differences between each test
port; therefore, an adjustment is required for each port.

a power meter, make the proper GPIB connections. Refer to “Get the
Hardware Required for your GPIB Instruments” on page 2-5.
2. Press Utility > System > Service > Adjustments.
3. In the Select Desired Adjustment dialog box, click Source Adjustment.
