6: Test Commands
Introduction
To obtain regulatory approval and carrier approvals for your product,
you may be required to perform tests on the radio component of the
embedded modem. This chapter describes AT commands used to
perform those tests.
Warning:
These commands are intended for use by developers, not
end-users. The commands should be used only in a controlled network
environment.
In most cases the modem must be in a particular mode before you
can issue the AT commands to perform particular tests. Therefore,
the order in which you issue certain commands is important. Three
AT commands are important in setting the mode:
•
—puts the modem in factory test mode (a non-
signaling mode). You must issue
AT!DAFTMACT
before issuing
any other command that starts with “
!DA
”.
•
—selects the frequency band.
•
—selects the channel. This command must be run
after you have selected the band with
!DASBAND
. (If you don’t
select a channel, the modem uses a default.)
