i. Take the measurement.
j.
AT!DASTXOFF (Turn off the transmitter.)
3. 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
adjustments are needed.
· For GSM mode, the transmit signal is bursted, so the transmit power will
appear averaged on the power meter reading.
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).
Note: When doing the same test over the air in an RF chamber, values are likely to be
significantly lower.
UMTS (WCDMA/GSM) RF receive path test
Note: This procedure segment is performed in Step 14 of the Production test procedure on
page 78.
The suggested test procedure that follows uses the parameters in .
