Measuring Maximum RF Output Power

HPBASIC Programming Example

10 ! re-save "c:\hpbasic\MAX_POW"
20 ! This program implements CDMA Max Output Power test.
30 ! This closely follows T36 from the 83217A Software.
40 !
50 Initialize_ts ! Initialize test set routine
60 Page_phone ! Requires the phone to have been previously registered
70 Max_output_pow
80 OUTPUT 714;"CDMA:CALL:END"
90 DISP "PROGRAM DONE"
100 END
110 Max_output_pow: SUB Max_output_pow
120 CLEAR SCREEN
130 DISP "Measuring the mobiles' maximum output power..."
140 OUTPUT 714;"CDMA:TX:POW:MEAS 'Avg Power';:MEAS:CDM:AVG:STAT ON"
150 !The following 5 lines set up parameters that
160 !help drive the phone to its maximum power
170 OUTPUT 714;"CDMA:CELL:CONF:NOM:POW 7"
175 OUTPUT 714;"CDMA:CELL:CONF:INIT:POW
180 OUTPUT 714;"CDMA:CELL:CONF:STEP:POW 7"
185 OUTPUT 714;"CDMA:CELL:CONF:NUMS
185 OUTPUT 714;"CDMA:CELL:CONF:MAXR 15"
190 OUTPUT 714;"CDMA:CELL:ASEC:PIL -7dB;SYNC -16dB;PAG -12dB;TRAF -7.4dB"
200 OUTPUT 714;"MEAS:CDM:AVGP:UNITS DBM"
210 !Lower Ior to increase mobile power
220 ! Do this in short steps to prevent dropping a call. Also, the IS-98
230 ! specifies -104 dBm/BW, but most mobiles will output max power at
240 ! -90 dBm/BW. The test may be more reliable at -90 dBm/BW if the mobile
250 ! receiver has difficulty at -104 dBm/BW.
260 OUTPUT 714;"CDMA:CELL:ASEC:BWP -90 dBm"
270 WAIT .5
280 OUTPUT 714;"CDMA:CELL:ASEC:BWP -104 dBm"
290 WAIT .5
300 Select 'Always Up' to send a continues stream of 'Up' power control bits

The following programming example was developed using HPBASIC for
Windows. It was tested on an HP 8924C with firmware rev A.02.29.
