Production Testing
Note: Production testing typically continues for the life of the product.
Production testing ensures that, for each assembled device, the module is installed
correctly (I/O signals are passed between the host and module), and the antenna is
connected and performing to specifications (RF tests).
Typical items to test include:
•
Host connectivity
•
Baseband (host/ module connectors)
•
RF assembly (Tx and/or Rx, as appropriate)
•
Network availability
•
Host/device configuration issues
Note: The number and types of tests to perform are your decision—the tests listed in this section
are guidelines only. Make sure that the tests you perform exercise functionality to the degree that
your situation requires.
Use an appropriate test station for your testing environment (see Acceptance Test
Requirements on page 66 for suggestions) and use AT commands to control the
integrated module.
Note: Your test location must be protected from ESD to avoid interference with the module and
antenna(s), assuming that your test computer is in a disassembled state.
Also, consider using an RF shielding box— local government regulations may prohibit unauthorized
transmissions.
Functional Production Test
This section presents a suggested procedure for performing a basic manual functional
test on a laboratory bench using an EM7411 Embedded Module and a hardware
development kit. When you have become familiar with the testing method, use it to
develop your own automated production testing procedures.
Suggested Production Tests
Consider the following tests when you design your production test procedures for devices
with the AirPrime module installed.
•
Visual check of the module’s connectors and RF assemblies
•
Module is operational
•
USB connection is functional
•
LED is functional
•
Power on/ off
•
Firmware revision check
•
Rx tests on main and auxiliary paths
•
Tx test
