FAQ

Product-specific questions

Product-specific answers based on available technical information.

Does every USRP-2943 have the same bandwidth?

No. NI specifies 40 MHz and 120 MHz versions. This record describes 40 MHz; confirm the unit label.

Which host interfaces are documented?

The NI-USRP 17.2 readme lists Gigabit Ethernet and PCI/MXI Express x4 for the USRP-2943.

How does the USRP-2953 differ?

NI maps both models to X310 + CBX hardware, but explicitly includes GPSDO in the USRP-2953 configuration. Their listed RF range and channel counts match.
