Testing
This section contains a product development checklist of parameters to
check, requirements to meet, and standards of performance to evaluate.
You can use these process checks and functional test procedures to
fully qualify that the Boomer II OEM Modem is well integrated with
the host device or terminal.
Proper testing throughout the development and integration cycle
ensures that the final product works in both normal and exceptional
situations. These tests are provided in several stages as follows:
1. Hardware integration
2. Desense and EMI
3. Regulatory compliance
4. Application software
5. Final assembly
6. End user problem resolution
7. OEM service depot repair
Hardware Integration
To ensure that the integration effort is carried out properly, monitor all
relevant engineering standards, requirements, and specifications. In
addition, perform functional tests during product development to
validate that the integrated package performs as designed.
Enabler Functions
To test the interaction between the modem and host, your product must
be able to perform the following:
Turn the various hardware components on and off. This
capability helps to isolate possible desense and other emissions
problems. (See “Desense and EMI” on page 68.)
Pass data through the host between the modem and the test
platform. This allows external programming and configuration
software to communicate with the modem while it is integrated
within the host. For microprocessor-based products, pass-
through mode uses software emulation involving the host
processor, which passes full-duplex serial port data to and from
the integrated modem. Otherwise, pass-through mode is
implemented in hardware by level shifting between the 3.3V
CMOS levels and the 12V RS-232 levels generally found on
PCs.
Specific Tests
In addition to the various tests that exercise your own circuitry, such as
power-on self-test, design tests that ensure proper interaction between
