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 MC8xxx 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.
Testing RF Receive path—MC57xx
Note: This procedure segment is performed in Step 14 of the Suggested production test
plan procedure on page 72.
To test the DUT’s receive path:
Note: This procedure
describes steps using the
Agilent 8648C signal
generator—the Rohde &
Schwarz SML03 is shown
for reference only.
