Hi everyone,
I am having some trouble getting the Phaser up and running (including I/Q upconverter).
One problem is the very low output power, I cannot get above approximately -10dBm for a single carrier. Can someone with a Phaser at hand or the required knowledge confirm, that the exmaple.py at https://github.com/quartiq/phaser/blob/master/example.py produces five carriers with different amplitudes, while the highest reaches approximately -20 dBm?
Below is a screenshot
Phaser output power
Sounds very much like what I got as well without any tweaking.

and others from

But do note that the default upconverter parameters are probably not useful.
