Residual Measurement Examples
Amplifier Measurement Example
This example contains information about measuring the residual noise of
two-port devices. It demonstrates a residual phase noise measurement for an
RF Amplifier. Refer to
more information about residual phase noise measurements.
To prevent damage to the test set's components, do not apply the input signal to the
C A UTI ON
signal input connector until the input attenuator has been correctly set for the
desired configuration, as show in
the connection diagram appears.
Required equipment
This measurement requires the following equipment:
• RF amplifier
• Stimulus source (frequency of amplitude under test)
• Power splitter (NARDA 30183)
• Coaxial cables and adapters necessary to connect the DUT and reference
To ensure accurate measurements allow the DUT and measurement equipment to warm up
NO T E
at least 30 minutes before making the noise measurement.
The setup for a residual phase noise measurement uses a phase shifter to set
quadrature at the phase detector. See
