Testing
1.
Set up the power meter:
Note: This procedure describes steps using the "Power Meter: Gigatronics 8651A” (with
Option 12 and Power Sensor 80701A).
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:
a. AT!ENTERCND=”<password>” (Unlock extended AT command set.)
b. AT!DAFTMACT (Enter test mode.)
c. AT!DARCONFIG=0,1,<bandValue>,<channel>
(e.g. AT!DARCONFIG=0,1,2,9400)
(Set frequency band and channel.
See Table 3-1 for values.)
d. AT!DAWTXCONTROL=1,<power_dBm>
(e.g. AT!DAWTXCONTROL=1,10)
(Enable Tx power output.
<power_dBm> = -57.0 to 23.0)
e. Take the measurement.
f. Repeat steps c–e with different Tx power levels if needed.
g. AT!DAWTXCONTROL=0 (Disable Tx power output.)
h. AT!DARCONFIGDROP=1 (Drop the current UMTS configuration.)

Test limits— Run ten or more good DUTs through this test procedure to obtain a
nominal output power value.
·
Apply a tolerance of ±5 to 6 dB to each measurement (assuming a good setup
design).
·
Monitor these limits during mass-production ramp-up to determine if further adjust-
ments are needed.
Note: The module has a nominal output power of +23 dBm
±
1 dB in WCDMA mode. However, the
value measured by the power meter is significantly influenced (beyond the stated
±
1 dB output
power tolerance) by the test setup (host RF cabling loss, antenna efficiency and pattern, test
antenna efficiency and pattern, and choice of shield box).
