Q: FAQ: RF Testing in production

The prototypes and the first batch should go through qualification testing.
For later batches, samples can be submitted to qualification tests and remaining devices to production test.
The level of testing must be seen in connection with cost and consequence of failure or poor performance as well as
stability in manufacturing processes.

Qualification test:

  1. Centre frequency
  2. Output power
  3. Output spectrum, adjacent channel power
  4. Harmonics levels
  5. Error Vector Magnitude
  6. Sensitivity level/Packet Error Rate test (PER test)
  7. Current consumption in various modes: Voltage regulator off, Power down, Transmit and Receive.


The tests may be determined by the instruments that is possessed
