¶ USRP N210 (USRP2 family)
Ettus's first Ethernet-attached USRP — the workhorse SDR in the WINLAB
grid and several sandboxes for the better part of a decade. Single
RF daughterboard slot (mono or quadrature), gigabit Ethernet host
interface, Spartan-3A FPGA. Successor to the Gen-1 USRP;
predecessor to the X310.

¶ Typical daughterboard
Every N210 in the grid and sandboxes is populated with an SBX
(400 MHz – 4.4 GHz, 40 MHz instantaneous BW) on the A side. The B side
is unpopulated.
¶ Host wiring
Each N210 is wired to the third Ethernet interface (eth2) of the
Gen-3 node directly above it on the
shelf. That interface is dedicated to SDR traffic and is on a
non-routed, non-Internet "data-A" subnet. Use uhd_find_devices
on the node to discover the radio.
¶ Antenna
The N210 antenna pair sits on the lab-side mounting bracket beside
the node — see the indoor antennas page
for the exact placement.
¶ Deployment
The N210 is by far the most common SDR in the grid (20+ nodes). See
the USRP deployment maps page
for the per-node placement, including SB1, SB3,
and SB7 (decommissioned 2026-05-03).
