Production test using DTM :Tolerance

[Chatelain Charly]

Hi, I use the DTM for the production test, I use the transmitter test ,with canal 19 (frequency = 2438MHz).

What is the tolerance of the frequency do you recommend (Min / Max)? And need to check other channels?

Thank in advance.

Best Regards,

Charly

Hi,

Are you testing with constant carrier? If so, then the requirement is +/- 40 ppm: 2438*10^6 * 40/1000000 = 97520 [Hz] The carrier can then deviate +/- 97.52 kHz from 2.438 GHz
