Thanks for your prompt reply.
We have tried using ramping with the CC1101+CC1190 868MHz EM. Two things I observe:
- SmartRF Studio (1.10.3) seems to disallow the use of PA ramping when used with the CC1101/CC1190 combo board? Is this intentional?
Clicking the 'PA ramping' check-box causes no changes in register view. (i.e. FREND0 stays at 0x10, and only PATABLE0 is populated)
- If I force ramping on by a) populating the PATABLE fully, and b) changing FREND0 to be 0x17 then I noticed the noise performance gets much worse on the EM. (I have a plot of this if interested)
Perhaps is is not a coincidence that PA ramping cannot be enabled on SmartRF studio with the CC1101/CC190 combo boards for this reason?
