Fields

210NEXT I

Screens Where Field is Present

CDMA MOBILE REPORTED PILOT STRENGTH

Swept Pwr (CDMA Swept Power Measurement)

This field allows for arming the swept power measurement.

GPIB Example

“CDMA:SWEPtpower:TRIGger[IMMediate]“

arms the measurement.

Operating Considerations

Selecting Arm prepares the Test Set to expect an amplitude trigger from the mobile station so that the Test Set can perform a swept measurement.

It is also necessary to send the following command once before arming the measurement:

“CDMA:SWEPtpower:TRIGger:MODE:\RETRigger:SINGle“

Screens Where Field is Present

CDMA SWEPT POWER MEASUREMENT (When the Controls field is set to Main)

Sync (Sector A Power)

This field allows the entry of Sync Ec, the sync channel energy per PN chip relative to the total sector power.

GPIB Example

“DISP CGEN;CDMA:CELL:ASECtor:SYNC:POWer -16“

sets Sector A pilot power to 16 dB.

Operating Considerations

As the sync level is varied, OCNS is automatically adjusted so that the total power levels of pilot, sync, paging, traffic, and OCNS add up to Sector A power, Ior.
