8 Product Testing
8.1 u-blox in-line production testing
As part of our focus on high quality products, u-blox maintain stringent quality controls
throughout the production process. This means that all units in our manufacturing facilities are
fully tested and that any identified defects are carefully analyzed to improve future production
quality. The Automatic test equipment (ATE) deployed in u-blox production lines logs all
production and measurement data – from which a detailed test report for each unit can be
generated. Figure 1 shows the ATE typically used during u-blox production. u-blox in-line
production testing includes:
• Digital self-tests (firmware download, MAC address programming)
• Measurement of voltages and currents
• Functional tests (host interface communication)
• Digital I/O tests
• Measurement and calibration of RF characteristics in all supported bands, including RSSI
calibration, frequency tuning of reference clock, calibration of transmitter power levels,
etc.
• Verification of Wi-Fi and Bluetooth RF characteristics after calibration, like modulation
accuracy, power levels, and spectrum, are checked to ensure that all characteristics are
within tolerance when the calibration parameters are applied.

8.2 OEM manufacturer production test
As all u-blox products undergo thorough in-series production testing prior to delivery, OEM
manufacturers do not need to repeat any firmware tests or measurements that might otherwise
