Fields

Then, to measure maximum power, the Test Set sets Sector A power to -104 dBm/ BW, turns the Call Drop Timer “Off”, and sends “Always Up” power control bits to the mobile station, using a procedure similar to the EIA/TIA IS-98 test “Maximum RF Output Power”. An Average Power measurement is made, and the Test Set is returned to closed loop power control mode.

CDMA TRANSMITTER POWER RANGE TEST

Min/Max Pwr

This field allows execution of mobile station minimum and maximum power measurements.

GPIB Example

“DISP CTXR;MEASure:CDManalyzer:MMPower:[EXECute]”

causes the Test Set to execute a Min/Max Power measurement.

Operating Considerations

While a mobile station is on a call, the mobile station’s range of power levels can be obtained by selecting the Execute field under the Min/Max Pwr label. Before Min/Max Power is executed, make sure that the Average Power measurement is zeroed, and the Channel Power measurement is calibrated. (Refer to “Calibrating the Test Set” chapter in the E8285A Application Guide, if you do not know how to zero Average Power measurements and calibrate Channel Power measurements).

The Test Set will measure the mobile station’s minimum power first. Using a procedure that closely follows the EIA/TIA IS-98 test “Minimum Controlled Output Power”, the Test Set sets Sector A power to -35 dBm/BW and Traffic Ec/ Ior to -7.4, then sends “Always Down” power control bits to drive the mobile station to its minimum power level. A Channel Power measurement is made, and the Test Set is returned to closed loop power control mode.
