2. Set up the DUT:
a.
AT!UNLOCK=”<customerCode>” (Unlock extended AT command set.)
or
AT!ENTERCND (Unlock extended AT command set.)
b.
AT!DAFTMACT (Put modem into factory test mode.)
c.
AT!DASBAND=<band> (Set frequency band.)
· See Ta b l e 8 -2 on page 81 for <band> values
d.
AT!DASCHAN=<channel> (Set modem channel)
· See Ta b l e 8 -2 on page 81 for <channel> values
e.
AT!DASLNAGAIN=0 (Set the LNA to maximum gain.)
f. (WCDMA mode)
i.
AT!DAWGAVGAGC=9400,0 (For PCS1900, channel 9400 as an
example.)
(GSM mode)
ii.
AT!DAGSRXBURST=0 (Set to receive bursted mode.)
iii.
AT!DAGGAVGRSSI=190,0 (For channel 190, for example.)
The returned value is the RSSI in dBm.
3. Test limits—Run ten or more good DUTs through this test procedure to
obtain a nominal received power value.
· Apply a tolerance of
5 to 6 dB to each measurement (assuming a good
setup design).
· Make sure the measurement is made at a high enough level that it is not
influenced by DUT-generated and ambient noise.
· The Signal Generator power level can be adjusted and new limits found if
the radiated test needs greater signal strength.
· Monitor these limits during mass-production ramp-up to determine if further
adjustments are needed.
Note: The value measured from the DUT is significantly influenced by the test setup and
DUT design (host RF cabling loss, antenna efficiency and pattern, test antenna efficiency
and pattern, and choice of shield box).
Note: Diversity is not
available in GSM mode.
4. Test diversity paths:
· MC8201 (WCDMA 850/WCDMA 1900)
· MC8780 (WCDMA 850/WCDMA 2100)
· MC8781 (WCDMA 850/WCDMA 1900)
· MC8790/MC8790V (WCDMA 850/WCDMA 1900/WCDMA 2100)
· MC8700/MC8795V (WCDMA 850/WCDMA 900/WCDMA 1900/
WCDMA 2100):
a. Set up the signal generator as in Step 1.
Note: Setup of the DUT is
the same as in Step 2,
except for a change to
AT!DAWGAVGAGC and
the addition of
AT!DAWSSCHAIN.
b. Set up the DUT:
i.
AT!UNLOCK=”<customerCode>” (Unlock extended AT command set.)
or
AT!ENTERCND
ii. AT!DAFTMACT (Put modem into factory test mode.)
