TEST MODE

To enter this mode, select TEST MODE as described in the section titled “Agilent 8922M/S Operating Modes”.

In TEST MODE, the Agilent 8922M/S no longer controls the mobile phone. The TEST MODE is used when it is not desired, or not possible, to set up a call between the Agilent 8922M/S and the mobile phone.

The MOBILE PHONE area available in Active Cell controls three functions simultaneously:

•The traffic channel transmitted by the Agilent 8922M/S.

•The traffic channel transmitted by the mobile phone.

•The corresponding channel used by the Agilent 8922M/S to measure the mobile phone.

In Test Mode, these functions are now separated. The traffic channel transmitted by the Agilent 8922M/S is now controlled by the Traffic Chan parameters, (1), see Figure 2-3 on page 2-10. The mobile phone’s transmission must be controlled manually using the mobile phone manufacturer’s service and test modes. The Agilent 8922M/S measurements are controlled by the fields below Expected Input, (2), see Figure 2-3 on page 2-10.

These fields are:

•Channel

•TX Level

•Burst Type
