HelloI'm unsing a MXA N9020A with VSA software for GFSK demodulation .

I need to define in my measurement report (GFSK deviation and index modulation) the deviation uncertain.

How to calculate the uncertain in this measurement ?

Thanks for the support adn for any help...

Hi Daniele -

The 89600 VSA software does not specify measurement uncertainty, only the minimum value you can expect to measure.

Dear tabbot

thanks for the reply.

Ok, so if I want to calculate the demodulation uncertain of the N9020A I need to use this formula :

(+/- 1% of rate+deviation) + 20Hz

Is correct ?

Hi Daniele -

The accuracy of this measurement is not specified. Since the accuracy is not specified there is no way to determine the measurement uncertainty.
