Rodney, I have a Spectrum Analyzer that goes up to 4 Ghz that can give you a pretty good not super precise idea if you can’t find something better. What you really want is an RF Power Meter- these use a calorimetric approach and give you RMS power no matter your waveform. I don’t have one. My spectrum analyzer gives good results for CW but will read only peak on any modulated waveform- BT is OFDM I believe. We could fake it by looking at its readings vs. a “good” BT waveform.

I have a device (for work) that is supposed to be putting out 20 dBm and I would like to confirm how close we can get to that. I have a small SMA output from the board and need a power meter that can measure the total radiated power across the Bluetooth frequencies (frequency hopping is enabled). This would be as a special favor to me as I do not have the authority to make a payment on behalf of my company, but if this test is successful, I do think it could generate opportunities in the future. I would also need to get this approved by work before I can show up with a device, but before approaching them, I wanted to see if there is anyone that can run this test for us. Thanx, Rodney
