Hey folks,

The Knowledge Base webpage for the SBXs daughterboards [1] mentions that
their maximum output power is 100 mW (20 dBm), and that the transmit gains
range goes from 0 to 31.5 dB.

Does this mean 20 dBm is the power output when the gain is set to 31.5 dB?

Also, the X300 Starting Guide [2] mentions that you shouldn't apply more
than -15 dBm to any RF input. If I use 30 dB of attenuation in a loopback
configuration (actually, TX/RX from one X310 to RX2 of another), and
considering the answer to my last question is positive, would ~25 dB of TX
gain be the overall maximum value you can use?

Thanks in advance!

Leo
