My thought is the DC cancellation circuitry in the 9361 is killing
your AM waveform, so use a low-IF approach instead.

You beat
Hi brian,
You are absolutely correct !
after i shifted 2Khz , i can get the expected signal..
In term of usrp sink (AM Tx), do you think that the same condition might
occurred?
Thank you

-20dBM is loud. Try backing the generator down to -40dBm

I set the generator at -20db and b200 gain at 50..
I check that there is no cutoff at the usrp output and the input to AM
demod block..
Below are the setting of uhd block in gnuradio
Samp rate 500k
Output type float32
Sync PC clock
Clock rate 10 Mhz external
Freq 121MHz
Gain 50
Ch0 Bandwidth
What output level for the generator? What gain setting on the b205?

Dear USRP users,
I used b210mini and encounter I/Q imbalance as below picture..
As a result, the analog signal demodulation was distorted and result a
crappy sound..

Is there any workaround regarding this issue?
Thank you
Not
