LTE RF receive path test

Note: This procedure segment is performed in

Step 13

of the

Production test procedure on

page 74

Table C-3

contains parameters used in the suggested test procedure that follows.

To test the DUT’s receive path (or diversity path, while connected to the diversity
antenna):

Note: This procedure
describes steps using the
Agilent 8648C signal
generator — the Rohde &
Schwarz SML03 is shown
for reference only.

Set up the signal generator:

Set the amplitude to -70 dBm

Set the frequency for the band being tested. See

Table C-3

for frequency

values.

Set up the DUT:

AT!ENTERCND

(Unlock extended AT command set.)

AT!DAFTMACT

(Put modem into factory test mode.)

AT!DASBAND=<band>

(Set frequency band.)

See

Table C-3 on page 81
