Software Defined Radio UK for Security Testing

SDR hardware for authorised testing

Software defined radios process radio signals using configurable hardware and software rather than a fixed-purpose receiver. In authorised engagements, they can support spectrum surveys, interference investigation, protocol research, signal classification, wireless resilience testing and controlled laboratory work. Use them only with appropriate permission and within applicable radio regulations.

For broader development work, SignalSDR Pro covers 70 MHz to 6 GHz and provides two transmit and two receive channels, full duplex operation, a 12-bit resolution, 61.44 MSPS sampling and a GPS-disciplined oscillator. It also offers Gigabit Ethernet, USB 3.0, GPIO and external clock support. These features suit teams integrating SDR hardware with tools such as GNU Radio, MATLAB or LabVIEW.

KrakenSDR is designed for multi-channel direction-finding work. It is a relevant choice for authorised KrakenSDR direction finding projects where phase-coherent channels and a suitable antenna arrangement are required. BladeRF 2.0 Micro xA4 is a compact, programmable SDR platform for engineers who need flexible transmit and receive development across supported frequencies. It is the Nuand bladeRF option in this range, so review Nuand's current specifications and software compatibility before selecting a bladeRF for a project.

PortaPack H4M Pro adds a portable interface to compatible HackRF-based workflows, making it suitable for field observation, education and controlled lab use. The TinySA Ultra+ and LiteVNA serve different measurement needs: TinySA Ultra+ is a spectrum analyser, while LiteVNA is a compact vector network analyser for examining antenna and RF network characteristics. Neither should be treated as a substitute for a general-purpose transceiver.

Choosing an SDR for the UK and Ireland

• Choose a transceiver for signal-processing development, controlled transmit tests and receive work. Choose an analyser or VNA for measurement and verification.
• Check tuning range, instantaneous bandwidth, channel count, clock accuracy, connectors, computer interfaces and software support against the test plan.
• Prices are shown in GBP or EUR, with USD also available. VAT is calculated at checkout.
• Transmitting is regulated in the United Kingdom and Ireland under Ofcom licence-exempt rules and the Wireless Telegraphy Act; receiving and analysing signals for authorised testing is the normal use.
• Review Ofcom and ComReg requirements, licence conditions, interference limits and any export-control obligations before importing or operating equipment.
