nRF52840 specifications for FCC Testing

[clockis]

Greetings,

We have a custom product based on the nRF52840 and we are preparing to test it for the FCC Certification.

For this the testing lab required some information on some specifications we are not 100% certain on, so if you could please provide them it would be really helpful.

1. Modulation technique (e.g. FHSS)
2. Modulation type (e.g. GFSK, O-QPSK PHY)
3. Number of Channels 
4. Hopping Channel Type (e.g. Adaptive Frequency Hopping systems)

Thank you very much for your time and I look forward to hearing from you.

Best regards,

Stavros

Hi Stavros,

Here are the details that you have asked for:

Modulation Technique: Digital Modulation (See Digitally modulated system under 15.247 (a)(2): https://www.ecfr.gov/current/title-47/chapter-I/subchapter-A/part-15/subpart-C/subject-group-ECFR2f2e5828339709e/section-15.247#p-15.247(a)(2))

Modulation type: GPSK
Number of Channels: 40
Hopping Channel: Not applicable since BLE is not FHSS.

Best Regards,

Swathy
