Ettus Research USRP's - User Opinions

... but USB3 and up to 56 MHz of bandwidth seems pretty nifty.

What's the max you can look at for bandwidth with the USRP1 and WBX daughterboard? Am I correct in that about 16 MHz might be it?

Gig Ethernet is the way to go, supports remote access and the box will only have it IF it NEEDS it (unless it is poorly designed, (rare), or partially overspeced).

To answer your question:

The USRP1's WBX has a 40 Mhz bandwidth, the ADC can digitize at 64 MS/s, and the USB 2.0 Interface does 8 MS/s (Half Duplex). That means a sweep of that bandwidth with so slow an ADC will make for a slow sweep time, hope you do not retrieve much Data (and you WILL) since you need to shove your 'answer' through USB 2.0 .

The USRP1 would be overkill if DSD is all it will ever be used for and likely unsatisfying IF you later get serious about the Hobby.

IE: I would buy one of the USB 3.0 Devices instead of a USB 2.0 Device, just because the USB 3.0 Interface is EIGHT times faster (and thus somewhat useful). Even a 100M Ethernet Device will be somewhat futureproof (for you, I presume, (too much?)), since you may not want a 1GE Box, and the massive expense of pro equipment.


Note: The actual streaming performance will depend on the processing capability of the host computer, the complexity of the application/DSP, and other factors.

The Mfg (Ettus) even suggests that the USRP1 is outdated and recommend a newer model. For the price of their other Model you can get this: http://www.zedboard.org/product/zynq-sdr-ii-eval (or any number of other newer Devices from various places). OTOH Ettus is much cheaper than NI (who makes their stuff and seems to have similar Devices for a much higher price).
