Fields

Mobile Power Mode

This field allows selection between two CDMA Channel Power measurement modes, providing for Channel Power measurements without a call connected. The choices available are:

Normal (call connected)

User (requires user to enter mobile power into Mobile Pwr field)

When “User” is selected, the Mobile Pwr field is displayed below it. When the Mobile Pwr field is displayed, the Test Set requires the expected mobile power level to be entered in the Mobile Pwr field for Channel Power measurements.

GPIB Example

“DISP CTXR;CDMA:MOBile:POWer:MODE ‘User’;MPOWer 0“

selects CDMA power measurements without a call connected, and enters an esti- mated mobile power level of 0 dBm.

Operating Considerations

When this field is set to “User”, the Test Set’s normal autoranging capabilities are disabled. If a call is connected, the Test Set will attempt to drive the mobile station’s power level to the value entered in the Mobile Pwr field, instead of using the open loop law (mobile station power = -73 dBm + forward channel power).

If a call is not connected, the Test Set relies on the entry in the Mobile Pwr field matching the actual mobile station power level to set up analyzer path attenuation correctly. The value entered must be within 3 dB of the actual power level.
