Dear support community,
I make comparison waveform response using ADI IIO Oscilloscope and gnuradio-examples using cyclic-sine.grc. My hardware is Zedboard + FMCOMMS2 + latest image 2016_R2-2017_06_29.img.xz. On IIO Osciloscope, the parameters set to AD9361 Receive Chain and Transmit Chain are :
RF bandwidth =20MHz
DDS, frequency =1Mhz, scale =-12db, phase 90
Then I verify on Time domain, Frequency domain and Constellation are good shape condition. (Waveform IIO.png) . Then I close IIO Oscilloscope to open cyclic-sine and configure same parameters ( gnuradio flow graph.png) like IIO Oscilloscope and run the gnuradio.
However the response on QT Sink- time,frequency and constellation are not similar and worst shape (time sink.png and const sink.png).
There is anything wrong on my setup/configuration on gnuradio flow graph ?
