>From the customer support perspective: The E310 is a very nice device from an analog point of view, but be warned: The E310 is an embedded device; it runs Linux on its own CPU, and you have to develop your signal processing software to run on that CPU; if you need to do something with serious bandwidth, you might even have to resort to FPGA programming, because the CPU in the E310 definitely isn't comparable to a Laptop or desktop CPU in performance. It cannot really be used as a peripheral to a PC.
Generally, I do advise to use the E310 if you know you have a standalone application that requires operation with little power on limited bandwidths; and even then, I recommend that people get a B210 and develop their signal processing on a PC using that, before porting your software to the E310 (the UHD API is the same).
