Hello, I am currently looking to see what the highest possible sampling rate is for the ettus N321/N320. I see that the highest master clock rate is 250e6 Mhz, However, on the product website(https://www.ettus.com/all-products/usrp-n321/), it says that it can collect up to an instantaneous bandwidth of 200 Mhz, so I am led to assume that the maximum possible sampling rate is 400 Mhz. Is this true? If so, how do I configure my the ettus to collect at a rate of 400 Mhz without the rate being coerced back down to 250 Mhz. Thanks, Joe

Joe, Complex sampling does not require the sample rate to be 2x the highest frequency as is the case for real sampling. It only needs to be 1x. So, the 250MS/s sampling rate produces 250MHz of spectrum. But, there are anti-aliasing filters that reduce this to a usable bandwidth of 200Mhz.
