HAROGIC Technologies Showcased its RF test and measurement solutions at AOC Europe 2026, this week from May 19–21 in Helsinki, Finland. The company showcased its PXR IP68 rugged spectrum analyzer along with the SAN-400 40 GHz receiver module, highlighting both field-deployable and embedded approaches to RF spectrum analysis.
Spectrum Analyzer for Field Measurements
The PXR series spectrum analyzer is a handheld, real-time RF analysis instrument designed for operation across frequency ranges of 9 kHz up to 9.5 GHz, 20 GHz, or 40 GHz, depending on configuration. It supports a real-time analysis bandwidth of up to 100 MHz, allowing it to capture wideband signals and short-duration events without gaps. The instrument also offers high sweep speeds, reaching hundreds of GHz per second or higher, enabling fast scanning across large frequency spans.
The analyzer has a displayed average noise level (DANL) of up to -168 dBm/Hz, which allows detection of low-power signals in congested spectrum environments. It also provides phase noise performance in the range of −100 dBc/Hz at a 10 kHz offset, supporting accurate signal characterization.
Designed for deployment outside the lab, the unit features an IP68-rated enclosure and compliance with MIL-STD-810H environmental standards, enabling operation in environments involving dust, water, and mechanical stress. The analyzer weighs approximately 2.5 kg, includes a 10.1-inch touchscreen display, and offers a typical battery life of around 4 hours, supporting field use.
The platform also supports real-time processing functions such as spectrum recording, I/Q data streaming, and signal analysis, with optional embedded computing capability for on-device processing.
Compact 40 GHz Receiver for Embedded Applications
HAROGIC also showcased the SAN-400, a compact real-time spectrum analyzer and receiver module intended for integration into RF systems. The device operates from 9 kHz to 40 GHz and offers a real-time analysis bandwidth of up to 100 MHz, enabling wideband signal monitoring. It achieves a sweep speed of approximately 400 GHz/s, supporting rapid spectrum analysis across wide frequency ranges.
The module is based on a superheterodyne receiver architecture combined with FPGA-based digital signal processing, providing real-time outputs including spectrum data and digital I/Q streams. Its sensitivity is specified at around -141 dBm/Hz at 40 GHz, with a phase noise of approximately −86 dBc/Hz at a 10 kHz offset.
Designed for compact deployment, the module measures approximately 125 × 60 × 17 mm, weighs about 185 g, and consumes between 10 W and 14 W of power. It connects via USB Type-C and supports both Linux and Windows operating systems, making it suitable for embedded platforms and custom RF system integration.
Two Approaches to RF Spectrum Analysis
The products presented at AOC Europe 2026 reflect two different design approaches. The PXR series is built as a portable field instrument for direct, on-site measurement in challenging environments, while the SAN-400 is a compact receiver module intended for integration into larger RF systems and monitoring setups.
Together, these solutions address applications such as spectrum monitoring, RF testing, communications analysis, and system-level signal processing, where real-time wideband measurement is required.
