I’m starting to develop functional production tests on boards embedding an Airprime WP76xx module.
I perform the LTE tests as described in the Airprime WP76XX Product Technical Specification (12.5 LTE RF Transmission Path Test).
To make the measurements I use a CMW500 in no signaling LTE.
All measurements are “pass” (Power, EVM…) except the measure of frequency error.
Is it normal that there are frequency errors in this measurement configuration ?
Do you have information on the subject ?
