Connecting a
Mobile
A single RF connection is used to test the RF performance of a mobile. If you are
not using a PCS Interface, you connect the antenna port of the mobile to the RF
IN/OUT port of the Test Set. If you are using a PCS Interface, you connect the
antenna port of the mobile to the RF IN/OUT port of the PCS Interface. Audio test
connections are the same in all cases.
Most manufacturers have specific connectors which can connect the audio and the
RF signal to the Test Set. Figure 5 on page 1 38 shows how to connect a mobile to
a Test System without using a PCS Interface. Figure 6 on page 1 39 shows how to
connect a mobile to a Test System that includes the PCS Interface.
Rear-panel connections for the Cellular Adapter and PCS Interface are in Chapter
11, “Installing the Cellular Adapter,” on page 285.
DO NOT CONNECT
TO THE ANT IN PORT
ON THE FRONT
PANEL
Do not connect the antenna of the mobile to the ANT IN port on the front panel of the Test
Set. This will cause the overpower protection circuitry to activate when the mobile is
transmitting. Refer to the HP 8920 RF Communications Test Set User’s Guide for more
information.
