Question 1:
The maximum output power of the AD9361 for a single tone is 7dBm.
What would its output power be when transmitting a signal with a 10MHz bandwidth? How to calculate the theory power?
I did the following test:
Keeping the AD9361 configuration the same as for single-tone with a output power about 7dBm, I generated a 10MHz bandwidth signal and observed the marker power of approximately -27dBm on the spectrum analyzer. Is this reasonable?
I noticed that the power marked by the spectrum analyzer represents the total power for the RBW. Therefore, to calculate the total power of the 10MHz bandwidth signal, integration should be used. For example, if the RBW is 3kHz, then the total power is:
-27dBm + 10log10(10MHz / 3kHz) = 8dBm
This seems to correspond to the maximum output power of the AD9361 for a single tone.
Question 2:
Is the output power specified in the AD9361 manual the maximum integrated power across the channel?
