To test the DUT’s transmitter path:

Note: This procedure

describes steps using the

"Power Meter: Gigatronics

8651A” (with Option 12

and Power Sensor

80701A).

1. Set up the power meter:

a. Make sure the meter has been given sufficient time to warm up, if

necessary, to enable it to take accurate measurements.

b. Zero-calibrate the meter.

c. Enable MAP mode.

2. Prepare the DUT using the following AT commands:

AT!UNLOCK=”<lockCode>” (Unlock extended AT command set.)

AT!ENTERCND

b. AT!DAFTMACT (Enter test mode.)

AT!DASBAND=<bandValue> (Set frequency band.)

· See Ta b l e 8 -1 for appropriate <bandValue> values

AT!DASCHAN=<channel> (Set modem channel)

· See Ta b l e 8 -1 for appropriate <channel> values

e. (GSM mode only)

AT!DAGSTXFRAME=0, 1, 3000, 0( (Set Tx frame structure.)

AT!DASTXON (Turns on the transmit path.)

g. (WCDMA mode only)

AT!DAWSTXCW=0 (Use a modulated carrier.)

h. (WCDMA mode only)

AT!DASPDM=2, 455 (Set the power level, tunable from 0 to 511.)

i. (WCDMA mode only)

AT!DAWSPARANGE=3 (Set to high PA gain state.)

j. Take the measurement.

AT!DASTXOFF (Turn off the transmitter.)
