to maintain at the input to your test device. Compensate for the power loss of the power
splitter or directional coupler in the setup.
4. If you want the analyzer to ma$e more than one power measurement at each frequency
data point, press ~~~;~~' MWUX& @ @, (where n = the number of desired
iterations).
If you increase the number of readings, the power meter correction time will substantially
increase.

correction.
You can use the power meter calibration as a reference to calibrate the analyzer receiver to
accurately measure absolute power. The following procedure shows you how to calibrate the
receiver to any power level.
1. Set the analyzer test port power to the desired level:
2. Connect the power sensor to the analyzer test port 1.
3. 'Ib apply the one sweep mode, press:
Because power meter calibration requires a longer sweep time,,,you may want
power meter calibration is finished, return the number of points to its original
value and the analyzer will automatically interpolate this calibration.
The status notation PC will appear on the analyzer display. Port 1 is now a calibrated source
of power.
4. Connect the test port 1 output to the test port 2 input.
5. Choose a non-ratioed measurement by pressing:
This sets the source at PORT 1, and the measurement receiver to PORT 2, or input port B.
6. Tb perform a receiver error-correction, press:
The receiver channel now measures power to a characteristic accuracy of 0.35 dI3 or better.
The accuracy depends on the match of the power meter, the source, and the receiver.
