Note: When performing
RF tests, use a test
platform similar to those
shown in Figure 8-2 on
page 88 and Figure 8-3 on
page 89.
13. Test RF transmission, if desired:
· MC57xx—See Testing RF transmission path—MC57xx on page 76.
· MC8xxx—See Testing RF transmission path—MC8xxx on page 77.
14. Test RF reception, if desired:
· MC57xx—See Testing RF Receive path—MC57xx on page 79.
· MC8xxx— See Testing RF Receive path—MC8xxx on page 81.
Note: The GPS receiver
does not need to be tested
for UMTS (MC8xxx) or
CDMA (MC57xx) modules
supporting diversity
because RF connectivity is
validated by testing the
diversity receiver in
Step 14.
15. (MC8775V only) Test the GPS receiver, if desired. See See Tes t in g GP S
Receiver—MC8775V on page 83.
16. Test Audio loop-back. See Test Audio Loop-back—MC5727V/MC5728V/

a. If the network adapter was disabled in Step 6, re-enable it (same instruc-
tions, except click
Enable instead of Disable).
Note: To power-off the
module, drive W_Disable#
low for the required
minimum period. See State
change: Power off/on on
page 23 for details.
b. Set the W_Disable# signal low and confirm that the module powers
down:
· Windows systems—The Sierra Wireless items under the Ports (COM &
LPT) entry in Device Manager disappear as the module powers off.
· Linux systems—Enter the command ls
/dev/tty/USB*. The devices
enumerated in Step 5 will not appear after the module powers off.
