Calibrating for Increased Measurement Accuracy
Power Meter Measurement Calibration
To Calibrate the Analyzer Receiver to Measure Absolute Power
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:
(enter power level)
2. Connect the power sensor to the analyzer test port 1.
3. To apply the one sweep mode, press:
(enter power level)
NOTE Because power meter calibration requires a longer sweep time, you may want to reduce the
number of points before pressing
. After the 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. To perform a receiver error correction, press:
(enter power level)
The receiver channel now measures power to a characteristic accuracy of 0.35 dB or better. The
accuracy depends on the match of the power meter, the source, and the receiver.
