WP76xx - LTE tests - frequency error

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 ?


Hi @stephane.V

If you check the latest technical specs from https://source.sierrawireless.com/resources/airprime/hardware_specs_user_guides/airprime_wp76xx_product_technical_specification and follow section “12.5 LTE RF Transmission Path Test”, it’ll provide the list of AT commands you need to use to test the RF path.

Please ensure that your modem is up to date with the latest firmware. You should not encounter any errors. If you have specific question, please reach out to your distributor or Sierra wireless contact. Thanks.
