Hi Peter

Can this be what they are after? https://infocenter.nordicsemi.com/topic/nwp_034/WP/nwp_034/nwp_034_modem_rf.html

Hi Hi ketiljo,,

1. The customer needs to ensure that LTE performance is normal when shipping. What RF performance should be tested during mass production?

2. Please provide an AT instruction example for a mass production test.

Thank you for all your assistance.
Kind regards,

Hi Peter

It highly depends what you want to measure and test. It varies if you want to do production testing or evaluation testing. There are no defined tests for this.

The RF tests are just AT commands so it shouldn't be too complicated to script this.

Sorry for not being more specific.

Cheers,

Ketil

Hi ketiljo,

1. In China, general module manufacturers will provide upper computer software for connecting CMW500 and nRF9160 to realize non-signaling automated testing steps.

2. Do we have similar software from nordic to provide customers with automated tests?

3. If not, could you suggest the development team to make similar software?

Thank you for all your assistance.
Kind regards,

2. The CMW500 will be just a spectrum analyzer here, it depends what you want to measure. Bandwidth, output power etc.

3. Youi have refer to the CMW500 manual

4. For non-signaling, you have to use AT commands: https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/production_test/xrftest_tx_set.html

Hi ketiljo,

1.The above method is used to test the RF performance of nRF9160 by signaling.

What I want to know is:

2. How to use CMW500 to test nRF9160 in none signaling mode?

3. How should I set up the CMW500?

4. Which at commands should be sent to configure the nRF9160 module?

Thank you for all your assistance.
Kind regards,
Peter.Min
