I want to see what the actual power applied to a radio is rather than just what is seen in GUI. Is this possible?

Unfortunately not.
The only cli command in the AP regarding TX power is:
The only cli command in the AP regarding TX power is:
get txpower wifi0It returns:
rkscli: get txpower wifi0Note: Ruckus uses attenuation as opposed to the setting of power value in mW or dBm:
wifi0 transmit power set to max
OK
rkscli:
rkscli: set tx
Commands starting with 'set tx' :
set txpower : set txpower <wifi name> <max | half | quarter | eighth | min | 0 to -24dB from max power>
-- Set transmit power

Thanks Sean, I was hoping to see what power the AP applies when I change this setting.

If 0 = Max & Max is based on EIRP (lets say 20dBm based on UK EIRP Regs when using 2.4GHz)
If you have a 3 dBi antenna then a setting of 0 will configure the tx power value to 17dBm.
Half Power will be 3dBm down; Quarter Power will be 6dBm down etc etc

Hi Sean, this is exactly what I was thinking. Just wanted to see it with my own eyes rather than just assuming. Thanks again for the response.
I guess it gets slightly more confusing when using 5GHz and DFS channels because the AP max TX power comes into play rather than the reg max.

Just apply the same logic based on EIRP (I am using UK Regulatory Values) with 0 = MAX
EIRP
5GHz = 23dBm
5.4GHz = 30dBm
5GHz Example
Gain = 8dBi
Power = 15dBm
5.4GHz Example
Gain = 8dBi
Power = 22dBm
Note: You also you have to check the max TX power capabilities of the AP as when using 5.8GHz in the UK for MESH traffic and certain AP's only support max of 23dBm you are under EIRP in terms of link budget.

Hi Sean, where do you get 8dBi gain from? Datasheets I am looking at state physical 3dBi gain at 2.4 & 5GHz
