4-2 Bench Testing
Test Equipment and Connections
The equipment typically used for testing the MBV3-100* consists of a network analyzer, such as
the HP 8712 or 8713 series, a 60/90 VAC bench power supply, a cable simulator, a Motorola
model SSP-PIN power combiner, and a variety of jumper cables, adapters, and fittings.
Fabricate a cable simulator that you can configure to provide the desired cable loss in 1 dB
increments up to approximately 30 dB. Then, connect the test equipment as shown in
Figure 4-1.

CAUTION!
To protect the network analyzer, you must configure the SSP-PIN power combiner to block AC power from the input
port
.
To preserve signal quality, verify that all unused ports are terminated.
CAUTION!
Before you begin the following subsection, remove the input pad (
JXP-IN) before you apply power. This is necessary to
avoid damage to the hybrids.
