Re: [Discuss-gnuradio] Differences between USRP series

[John Malsbury]

Seokseong Jeon,

Your summary captures some of the differences between the USRP's.  If you haven't already, take a look at the link below for more details.  One thing to note is the USRP2 has been discontinued in favor of the N200/N210 series.

If you are interested in experimenting with MIMO, we recommend the N200/210.  The link below summarizes synchronization methods with the UHD API.  GNU Radio and GRC also provide very straight forward methods to enable MIMO.

Thank you for your interest!

There are various kind of USRP series, USRP1, USRP2, E100, B100, and N200.

At a glance I could find some differences between them.

1. USB connection and Ethernet connection which determines the data rate between the USRP and a PC.

(and it also makes difference when addressing USRP in GNU Radio.)

2. the number of slots for daughter boards. USRP1 has two and N200 has one, and so on.

3. E series are for the embedded systems.

4. existence of MIMO expansion

5. USRP input and output / interpolation and decimation rate

etc.

and there are many other differences, of course.

Are there any differences that I've missed?

And I'm curious how can I use the MIMO expansion after connecting two USRPs with MIMO cable.
