После покупки Ettus Research'а National Instruments'ами, дела у Еттуса явно пошли в гору. В марте 2011 USRP2 снимается с производства, её место займёт новая USRP N210 (pdf datasheet). Вкратце:

• Gigabit Ethernet
• Up to 50 MHz of full-duplex RF bandwidth
• Xilinx® Spartan® 3A-DSP3400 FPGA
• Dual 100 MS/s 14-bit ADCs
• Dual 400 MS/s 16-bit DACs
• Auxiliary analog and digital I/O to facilitate integration into a larger system
• FGPA is reconfigurable over the Ethernet using the internal Flash which replaces the SD cards used by the USRP2
• Multiple USRP N210 devices can be connected together to form MIMO systems
• Price is $1700

Ещё одна новая игрушка, в этот раз в продолжение серии USRP1 — USRP E100 (pdf datasheet) со встроенным Gumstix Overo — одноплатным компьютером на 720MHz OMAP™3 (ARM® Cortex™ A8 processor & TI C64x+ DSP):

• Xilinx® Spartan® 3A-DSP1800 FPGA
• Runs a full distribution of Linux enabling both development and deployment without the need for a host computer
• Two 64 MS/s 12-bit ADCs
• Two 128 MS/s 14-bit DACs
• Auxiliary analog and digital I/O facilitates integration into a larger system
• Price is $1300

В скором времени обещаю выкатить ещё модификаций. Вот выдержка из письма Эттуса в список рассылки от 17 ноября, объясняющая новую схему именования USRP и их ближайшие планы:

Each product number is one letter and 3 digits.  The letter denotes how the device is attached to the computer —
«B» stands for bus (i.e. USB)
«N» for network (ethernet in this case)
«E» for embedded computer

The first digit roughly indicates a product generation.  In this case, 2 for the 2nd generation of our network devices.

The 2nd digit indicates option levels.  In this case «1» indicates the larger S3A-3400 DSP FPGA.

The third digit indicates major revisions.  In this case we are on the zeroth revision.

Had this naming system been around when the USRP1 was introduced, it would have been called the USRP B100.  There's no point in renaming it now, so we'll continue calling it the USRP1.  Similarly, the USRP2 would have been called the USRP N100, but we won't be renaming it.

There is a USRP N200 planned for March which will have a smaller Spartan 3A DSP 1800 FPGA instead of the 3400 in the already-announced N210. This will cost $200 less than the N210 because of the smaller FPGA.

We also will be making a formal announcement very soon about the USRP E100 and USRP E110 which will be embedded radio systems with 2 different sizes of FPGA.

We have other products in development which will further exercise this new naming system :)
