Problem Solving

If the mobile station does not ﬁnd service

• Check parameters CP Mobile Network Code and CP Mobile

Country Code (see “Editing the test parameters” on page 27).

• Check the connection from the mobile station to the HP/Agilent

8922. The RF IN/OUT connector (not the AUX RF OUT or AUX RF IN

connectors) should be used.

• Check the LO OUT to LO IN connection on the HP/Agilent 8922 rear

panel. These connectors appear on older versions of the HP/Agilent

8922 and must be connected with a coax cable.

• If your HP/Agilent 8922 is equipped with Option 001, check that the

rear panel Opt 001 REF OUT connector is connected to REF IN with

a coax cable.

• If your HP/Agilent 8922 is equipped with Option 001, use a

frequency counter to ensure that the High-Stability timebase is on

frequency.

• If the Mobile Station is unable to make or receive calls, see SIM

Switching Problems.
