AM NOISG Using
This example demonstrates the AM noise measurement of
an HP 3 3 3 3 0 C
a n H P
8662A Signal Generator using an HP 33330C
Detector and a user-supplied filter network.
Required Equipment
The following equipment is required for this example in
addition to the standard HP 3048A system and your
device-under-test (DUT).

Enter in System Configuration Table.
(Refer to Appendix A.)
Recommended type is Narda 562
(Type-N connectors) or Narda 4563
(SMA connectors). The DC Block is
optional but should be used to
prevent ground loops from affecting
the measurement results.
2-foot BNC coaxial cables and
adequate adapters to connect DUT.
The schematic for the filter network is
shown in Figure 3-31 and must be
provided by the user as it is not
available from HP. The filter network
should be built in a small metal box
and should have connectors to
connect directly to the HP 11848A
Phase Noise Interface front-panel
"NOISE INPUT" connector. The
HP 33330C Detector should also
connect directly to the filter network
as shown in the Equipment Setup
Diagram, Figure 3-30.
