AM Noise using an Agilent/HP 70420A
Option 001
This example demonstrates the AM noise measurement of an
Agilent/HP 8662A Signal Generator using the AM detector in the
Agilent/HP 70420A Option 001 Phase Noise test set. For more information
about various calibration techniques, refer to
Measurement
Fundamentals".
This measurement uses the double sided spur calibration method.
The measurement of a source with amplitude modulation capability is
among the simplest of the AM noise measurements. The modulation
sidebands used to calibrate the AM detector are generated by the DUT.
Required Equipment
To prevent damage to the Agilent/HP 70420A test set's hardware
components, the input signal must not be applied to the signal input
connector until the input attenuator has been correctly set for the desired
configuration, as show in
when the Connection Diagram appears.
The following equipment is required for this example in addition to the
phase noise test system and your unit-under-test (UUT).
To ensure accurate measurements, you should allow the UUT and
measurement equipment to warm up at least one hour before making the
noise measurement.
