HAROGIC offers a rich variety of product forms and frequency options, covering both modular and handheld devices with USB and Ethernet interfaces. The frequency range includes 4.5/6/9/20/40 GHz, with a maximum sweep speed of up to 1 THz/s (RBW=250 kHz). All spectrum analyzers are professionally calibrated and are suitable for applications in testing, measurement, and software-defined radio.

HAROGIC developed the GNU Radio module called gr-htra to interface with and uiltize the measurement capabilities of a HAROGIC Spectrum Analyzer. The gr-htra Out-Of-Tree (OOT) module and the SoapySDR-based hardware abstraction layer library treat the HAROGIC hardware as a data source within the flexible GNU Radio platform. Users can acquire real-time IQ data streams from HAROGIC devices within GNU Radio and visualize multiple signal analysis views, including the spectrum, spectrogram, time-domain waveform, and constellation diagram. This integration marks the official inclusion of HAROGIC spectrum analyzers into the GNU Radio open-source ecosystem, offering users a more efficient and flexible solution for signal acquisition and analysis, and accelerating the adoption of high-performance spectrum analyzers in software-defined radio applications.

1 Introduction to Solutions and Application Examples

1.1 GNU Radio Platform Adaptation Solution

The HAROGIC gr-htra module implements driver support and data interaction for the spectrum analyzer in GNU Radio Companion. Users can load the HAROGIC HTRA: IQ Source block in the graphical interface without writing additional driver code, enabling real-time IQ signal acquisition and display.

In addition, HAROGIC supports the universal SoapySDR interface, further enhancing the device’s cross-platform adaptability and operational flexibility. The gr-htra OOT module is specifically designed for HAROGIC devices, delivering lower latency and higher execution efficiency on the GNU Radio platform, while the SoapySDR interface offers greater advantages in cross-platform compatibility and system flexibility. Users can quickly build various communication and signal analysis systems using either of these two integration approaches.

1.2 Example and Open-Source Project Support

HAROGIC provides typical signal processing and demodulation examples, including AM/FM analog demodulation and QPSK/QAM16 digital demodulation. It also supports open-source projects such as gr-adsb, gr-dab, and gr-ieee802-11, enabling ADS-B signal demodulation with flight path visualization, DAB digital broadcast signal demodulation, and WLAN signal demodulation.

All examples run directly in GNU Radio and offer a reusable framework that helps users verify algorithms, build prototype systems, and conduct communication experiments.

2 Extended RF Boundaries

HAROGIC continues to deepen its integration with the open-source ecosystem, providing flexible signal-processing solutions that expand application boundaries. Users can build on HAROGIC example projects to perform algorithm verification, system integration, and prototype development. The devices can also be connected to real wireless environments for spectrum monitoring and signal demodulation.
