Measuring Power from Splitter
2. Measure the power level that will be applied to the Signal Input port of
the Agilent/HP 70420A's Phase Detector. The following chart shows the
acceptable amplitude ranges for the Agilent/HP 70420A Phase
Detectors.

1. Agilent/HP 70420A Phase Noise Test Set Options 001 and 201
3. Measure the output power at the side of the power splitter where the
calibration source will be substituted, then terminate in 50 ohms.
4. Adjust the calibration source to the same output power as the measured
output power of the power splitter.
5. Adjust the output frequency such that the beatnote frequency is within
the range of the analyzers being used.
6. The system can now measure the calibration constant.
7. Disconnect the calibration source and reconnect the power splitter.
