Hello, dear Developer-Team,
I recently came across to situation, when I have to model 2 overlapping
signals within the same frequency but different power levels. I wanted
to
use variable IQ-envelope size for that - one signal with level of 0.2
and
another with 0.6. The max sum of 0.8 would be still fitting the allowed
DAC
amplitude of my USRP_N210.
BUT there seems to be some Automatic Gain Control for the digital
signal.
Independent if I set amplitude of my digital signal to 0.2 or 0.6, the
measured output in DB is the same.
How is it possible to switch that function off?
With the “self.uhd_usrp_sink_0.set_gain(5, 0)” I can do only the analog
output gain control.
Hope somebody have the solution,
With best regards,
Andis
