USRP E310 limited sample rate

Hi all,

I'm currently testing USRP E310.

When I check the functionality of E310, I found a limitation on its sample rate.

The test setup is TX (E310) transmits a sinusoidal signal (signal frequency 1k) continuously to RX (B210 with another host machine) with different sample rate(1M - 10M).

USRP Sink's center frequency is 5 GHz band and gain is 0.75 (normalized), and I've set its master clock rate 60 MHz.

When the sample rate is lower than 10 MHz, RX shows clear sine wave.

However, when I increased it to 10 MHz, the signal is crashed.

Is it the limitation of E310? Or I configured wrongly?

Any help would be great to me.

Best,

Jinhwan
