Radio Signal Analysis with HackRF SDR
Devices from the HackRF family enable radio signal reception and transmission using Software Defined Radio (SDR) technology. The HackRF One operates in the frequency range from 1MHz to 6GHz and supports half-duplex operation and sampling rates up to 20MS/s. It works with software such as GNU Radio, enabling spectrum analysis, modulation analysis and testing of custom wireless communication systems. SDR tools are used in RF laboratories, educational projects and authorized wireless communication security research.
Tools for Sub-1GHz and Bluetooth Communication Analysis
Analyzing wireless devices requires equipment suited to the operating frequency band and transmission method. The YARD Stick One supports the reception and transmission of digital radio signals below 1GHz, including selected modulation types such as ASK, OOK, FSK and GFSK. The Ubertooth One platform was developed for experimenting with Bluetooth communication in the 2.4GHz band. Both device families can be used for wireless protocol analysis, IoT device diagnostics and research into data exchange between devices.
Cynthion USB Analyzers for Protocol Diagnostics
Cynthion enables the capture and analysis of communication between computers and USB devices. The platform uses a programmable FPGA and supports USB Low-Speed, Full-Speed and High-Speed traffic analysis. Integration with Packetry software allows users to inspect transmitted packets and examine communication sequences, while LUNA and Facedancer tools support the development and testing of custom USB devices. These analyzers are used for interface debugging, reverse engineering and authorized security testing of peripheral devices.
Ethernet Traffic Monitoring with Throwing Star LAN Tap
Throwing Star LAN Tap devices enable passive traffic monitoring in 10BASE-T and 100BASE-TX Ethernet networks. Connecting the interface between two network devices allows traffic to be forwarded to an external analysis computer without configuring a mirrored port on a network switch. Separate monitoring ports enable observation of data transmitted in both directions using software such as Wireshark or tcpdump. LAN Tap solutions are designed for wired network diagnostics, packet analysis and Ethernet protocol research.
GreatFET One - Embedded System Prototyping and Analysis
GreatFET One provides programmable digital inputs and outputs along with SPI, I2C, UART and JTAG interfaces, enabling communication with microcontrollers, memory chips and other electronic components. The platform connects to a computer via USB and offers a Python programming interface for hardware control and automated measurements. Support for logic analysis, debugging and hardware extensions makes the device suitable for electronics prototyping, digital circuit diagnostics and embedded system research.
Antennas and Accessories for Expanding Test Setups
The category also includes accessories designed for use with SDR devices and measurement platforms. ANT500 and ANT700 telescopic antennas allow their length to be adjusted according to the operating frequency range, while Opera Cake enables software-controlled switching between antennas and RF signal paths connected to HackRF. Protective enclosures and expansion modules help prepare devices for laboratory use and integration with other equipment. Accessory selection should take into account the operating frequency band, impedance, connector type and compatibility with the intended device.
