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.

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

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.
