I am setting up production testing of our product to do RF testing per app note AN34. We are using the nRF51822 on our product. I'm using Nordic's development kit and their Python code. My setup is as per figure 2 of the AN34. The AN34 example code tests CH1 in both TX and RX and checks for a PER (packet error rate) of less than 30. The test then checks a series of channels (1,5,7,9) for both TX and RX, and it checks the PER for each channel and the total PER. The PER limit for all tests is 30. The last test in the example is an individual TX and RX PER on a channel, and the PER limit is 30.
Per the app note AN34, the Nordic chips are tested at the factory. Any RF testing that is needed will be to verify the antenna and any support components are installed correctly.
My question is: Can we do the RF DTM PER test by TX and RX on just the first (2.402GhZ) and last ((2.480 Ghz) channels? Do we need to check any specific channels or range of channels? What should the PER test limit be set at for each test?
