Hi, When using the UHD "tx_waveforms" example, I can see that the signal emitted by my N310 USRP is saturated when it’s not supposed to be.
Here's a snapshot of the signal when I set the amplitude to 0.003: .\tx_waveforms.exe --rate 12.5e6 --nsamps 1250000000 --freq 1575.42e6 --ampl 0.003 --otw sc16 --wave-type SINE --wave-freq 10e3 --channels 2 [image: tx_waveforms_3e-3_amp] <https://user-images.githubusercontent.com/15334138/46685506-a7424700-cbc3-11e8-926e-b0da5f416652.png> Here's a snapshot of the signal when I set the amplitude to 0.03: .\tx_waveforms.exe --rate 12.5e6 --nsamps 1250000000 --freq 1575.42e6 --ampl 0.03 --otw sc16 --wave-type SINE --wave-freq 10e3 --channels 2 [image: tx_waveforms_3e-2_amp] <https://user-images.githubusercontent.com/15334138/46685468-9265b380-cbc3-11e8-9ce7-42908cf9bf2e.png> As you can see from the pictures above, it seems that there's a saturation in the signal when the amplitude is set to 0.03 (which is unexpected with such a small amplitude). We have double-checked with a X300 device, and the signal is normal in both cases. Do you have an idea of what could be wrong, or a suggestion to try on our side?
