Nrf52833 ,Certification,RFPHY.ICS, IXIT for core information confirm

[jackh3c]

I have a Certification need to be done ,so please help to confirm these questions, thank you.

1, Capabilities items confirm, does 52833 support all these items? i think 1-7 are OK, how about others?

2,What is the value of this item 1 ? Does it should be 1000 ms ?

How about item 2?

About item 3, Does it should be 5?

3,Please help to check yellow parts as below if these are OK , i refer to this answer.

And i also have a question about this answer, why the antenna gain fix to 2.2 dBi? 

Thank you for you support.

Hi,

1, Capabilities items confirm, does 52833 support all these items? i think 1-7 are OK, how about others?

The features should be supported as the nRF52833 supports AoD and AoA.

And i also have a question about this answer, why the antenna gain fix to 2.2 dBi? 

This is probably due to the gain of the antenna that was used to make that report. You have to fill in the antenna gain of your specific antenna, in most cases it's 0dBi. 

I'll be back later with more information regarding your other questions.

Hi there,

I've discussed your questions with our RF engineer, and they said:

1. The modulation index is not stable. so Item 5 and 6 is not relevant.
2. TSPX_TIMER_TX_POWER_CONTROL is for BR/EDR and not Bluetooth Low energy. 
3. This is correct.
4. Antenna gain is unique, it depends on your antenna on your design.

hi Jared

thank you,

about question 2, hou about item 2 and item 3, these two also for BR/EDR, not for BLE? thank you.

[jackh3c]

hi Jared

how about this ? thank you.

[Jared]

Hi,

The two other items are relevant for BLE:

-2 MHz @ 1 Mbps og -4 MHz @ 2 Mbps. n = 5

You do not need to test this, RF-PHY has already been tested by us, what you need to do is a RF-phy retest. See this.
