How to get 122 MSp/s samplerate on BladeRF A4 with no signal interruptions

[prokino]

Hi.
I have BladeRF A4.
In my tests I want to play a bin-file with sinusoidal signal by BladeRF device with sampling rate 100 MSp/s.
But it can plays only on 80 MSp/s with no signal interruptions.
I switched "Oversample" mode on and use Asynchronius API.
In my test I use GNUradio for viewing signal and the other BladeRF device as a source RX.

Could you explain please, how to get 100 - 122 MSp/s samplerate with no signal interruptions?

You should have a high-speed USB connection (USB 3.0 or higherdoodle baseball) and a USB port dedicated to the BladeRF device only to maximize available bandwidth.
