Agilent Technologies E8285A manual Programming Example for Strength Field

Chapter 4, Description of Fields

Fields

Strength

This column in the CDMA Mobile Reporting table lists the power level most recently measured and reported by the mobile station for each pilot the mobile station is currently tracking.

All numbers displayed in the CDMA Mobile Reporting table reflect the last pilot strength message received from a mobile station. Before any numbers are displayed, a call must be connected and Sector B must be transmitting at a high enough power level to cross either of two thresholds set up by the T_Add and T_Comp fields.

The CDMA Mobile Reporting table can be cleared by selecting the Pilot Meas (Clear) field.

GPIB Example

“DISP CMOB;CDMA:MOB:PIL:STR?“

queries the results displayed in the CDMA Mobile Reporting table.

The value returned by the Test Set includes Status, PN Offset, Strength, and Keep for each pilot currently being tracked by the mobile station. These values are sent as a comma-separated list of IEEE floating point numbers, 16 characters each, ending with a line feed character.

NOTE:If no values are displayed in the CDMA Mobile Reporting table, the query example shown above will return only the line feed character.
