I am writing firmware for compliance testing using the AT+CW (send continuous wave) command. The maximum transmission power for this command is +22dBm, yet the maximum transmission power for the module is +30dBm in several bands (e.g. US915, txpower=0).
How can I appropriately demonstrate full compliance when +30dBm is not achievable in test mode?
I am not really an expert in compliance but probably you can share some detail so I can ask expert in our team regarding this matter. Some insights/questions I have.
Tests are EU and US radiated emissions testing. Is the +22dBm output limit shown in the datasheet anywhere? Also, does output power vary with supply voltage?
