Fields

OCNS (Sector B Power)

This field displays Orthogonal Channel Noise Simulator (OCNS). The Walsh

Code can also be specified for OCNS, but OCNS power is not settable.

GPIB Example

“DISP CGEN;CDMA:CELL:BSECtor:ORTHogonal:POWer?“

queries the relative power level of the Sector B OCNS source.

“DISP CGEN;CDMA:CELL:BSECtor:ORTHogonal:WALSh 17“

sets the Walsh code for the OCNS to 17.

Operating Considerations

OCNS is automatically adjusted so that the total power levels of pilot, traffic, and OCNS add up to Sector B power, Ior.

Allowable values for OCNS include Walsh codes 8 through 63. If a Walsh value is entered that matches the Traffic or Sync channel setting, an error message will be displayed.

Offset Freq

Frequency offset (RF Generator) sets the difference between the instantaneous frequencies of the Tracking Generator and the center frequency of the Spectrum Analyzer.

Operating Considerations

The offset can be a positive or negative value. When set to zero, the Tracking Generator produces a sweeping signal that matches the Spectrum Analyzer’s tune frequency.
