Table 2. Ettus USRP X420 Minimum Required System Components
Component Description
Ettus USRP module Ettus USRP models provide RF signal generation and acquisition, device‑level processing, timing and synchronization resources, and high‑speed data interfaces for software‑defined radio applications.
Host PC
Icon representing a desktop computer tower.

 A host computer runs control software and processes streamed data. Host performance requirements depend on sample rate, bandwidth, FPGA image, and application workload.
USRP Hardware Driver™
Icon representing application software represented by a document and gear symbol.

 Runs on the host PC and provides the APIs, tools, and drivers required to configure the Ettus USRP X420, control operation, and stream RF data.
Power supply
Icon representing an external power supply unit.
 The provided power supply delivers regulated power required to operate the Ettus USRP X420.

Additional Components for Ethernet Connectivity

The Ettus USRP X420 requires Ethernet connectivity to a host PC. The required network hardware and cables depend on the selected Ethernet configuration and FPGA image.

Table 3. Ettus USRP X420 Additional Components for Ethernet Connectivity
Component Description
Network switch
Icon representing a network switch.
 Used for RJ45 Ethernet configurations when a direct connection to the host PC is not available. The switch must support the required Ethernet speed.
CAT 5E Ethernet cable
Icon representing an Ethernet cable.
 Used for RJ45 Ethernet connections between the Ettus USRP X420, host PC, and optional network switch.
100 GbE network card Required in the host PC for configurations that use a QSFP28 100 GbE Ethernet connection.
10 GbE network card Required in the host PC for configurations that use a QSFP28 breakout connection.
QSFP28 to QSFP28 Ethernet cable Used for direct 100 GbE Ethernet connections between the Ettus USRP X420 and host PC.
QSFP28 to 4×SFP28 Ethernet breakout cable Used to connect the QSFP28 port on the Ettus USRP X420 to 10 GbE network ports on the host PC.
