Japan certification for nRF2401, carrier mode only

[Thomas Corvé]

Sir,

We are using your radio component in our system since many years. We are in the process to get conformity with Japanese rules.

The lab in charge of testing is asking us to continuously emit in carrier mode only , Is this possible ?

We tried a software to send only 0 (no information) but due to your modulation type there is always a modulation with the carrier.

Do you have any factory setting to send only the carrier ?

Do you have a certification of your radio with Japan conformity?

It’s very urgent as we need to deliver product to Japan next month , and the lab is asking one month to proceed.

Thank you in advance for a reply by return.

Kind Regards

Hi Thomas,

Have you tried the instruction in Appendix C "Constant carrier wave output for testing" in the nRF24L01P specification ?

Hi Thomas, Could you try this:

There is a 2 bit wide field in the configuration register, named PLL_CTRL, where you can lock the PLL. If you set both bits high, the PLL will be locked during TX operations. If you configure the nRF2401 to TX mode and in DirectMode, keeping the CE high will give you a fixed carrier out on the selected channel.

See page 20 in nRF2401A Product Specification
