Making the measurement
Calibrate the measurement using measured ± DC peak voltage
Refer to Chapter 7, “Residual Measurement Fundamentals for more
information about residual phase noise measurements calibration types.
Procedure
1
Using Figure 173 and Figure 174 on page 240 as guides, connect the circuit
and tighten all connections.
2
Measure the power level that will be applied to the Signal Input port of the
test set phase detector. Table 37 shows the acceptable amplitude ranges for
the test set phase detectors.

NOTE
Connecting an oscilloscope to the monitor port is recommended because the signal can
then be viewed to give visual confidence in the signal being measured. See Figure 173 and
Figure 174 on page 240.
