Configuring the HP/Agilent 8922 Multi-Band Test System
Zero the Power Meter
Checking the Current Status of the Power Meters
Use the following simple, manual method to check the current status of your Test
Set using a Dual-Band mobile:
1 Press the front panel to display the Cell Status screen and set the Operating
Mode to E-GSM.
2 Connect the mobile to the Test Set RF In port, power it on and wait for it to camp-on to
the Test Set BCH.
3 Establish a call and note the value of the Peak Power (Fast Power) measurement center
screen.
4 End the call and power off the mobile.
5 Remove the connection to the front panel to ensure no RF power.
6 Press the front panel to display the Cell Status screen and select the
field.
7 Repeat steps 2 and 3.
8 Compare the two Peak Power measurements. Any difference is most probably due to
the Power Zero meter.
9 Repeat steps 1 through 8 for the Radio Type set to DCS1800 (that is, to check the HP/
Agilent 83220 power meter).
