6 Product testing
6.1 u-blox In-Series production test
u-blox focuses on high quality for its products. All units produced are fully tested automatically in
production line. Stringent quality control process has been implemented in the production line.
Defective units are analyzed in detail to improve the production quality.
This is achieved with automatic test equipment (ATE) in production line, which logs all production and
measurement data. A detailed test report for each unit can be generated from the system. Figure 12
illustrates typical automatic test equipment (ATE) in a production line.
The following tests are performed as part of the production tests:
• Digital self-test (software download, MAC address programming)
• Measurement of current
• Functional tests
• Digital I/O tests
• Measurement and verification of RF characteristics in all supported bands (calibration not needed
since performed automatically by radio chip every 5 minutes during normal operation)
o Modulation and frequency accuracy
o Power levels
o Sensitivity

6.2 OEM manufacturer production test
As the testing is already done by u-blox, an OEM manufacturer does not need to repeat software tests
or measurement of the module’s RF performance or tests over analog and digital interfaces in their
production test.
However, an OEM manufacturer should focus on:
• Module assembly on the device; it should be verified that:
o Soldering and handling process did not damage the module components
o All module pins are well soldered on device board
o There are no short circuits between pins
• Component assembly on the device; it should be verified that:
o Communication with host controller can be established
