IWR6843: How accurate is the carrier frequency setting?

Part Number: IWR6843

In view of RF regulations

- specific frequency bands available for

- specified levels of emissions (in-band, out-of-band),

and further intents to operate in sub domains ('channels') with substantially narrower bandwidths,

what is the accuracy of carrier wave setting, profileCfg <startFreq>?

In essence,

a) what is the maximal deviation of the actual emitted frequency versus <startFreq> settings,

having accounted all the relevant sources of uncertainty, 

- such as dependencies of clock system on ambient conditions (temperature),

- aging of hardware,

- unit-to-unit variations of hardware,

- bit resolution (singe float?) of <startFreq> parameter

b) what is the resolution of >startFreq> ie. the smallest step change in the setting?  

I recon it's can be interpreted as a broad topic, pending on further specifications (levels of in-and versos out-of-band).

Any guidance of prior considerations, studies, welcome.
