1Overview
The Berkeley Nucleonics ICX-FieldHawk Rugged is a real-time spectrum analyzer built for solid RF performance in the field, on the flight line, and inside automated test racks. The series covers 9 kHz up to 9.5, 20, or 40 GHz with a standard analysis bandwidth of 100 MHz. A fast FFT design pushes sweep speed past 1 THz/s.
The rugged housing wraps the same measurement engine as the handheld ICX-FieldHawk in an impact-protected chassis with corner bumpers, so it holds spectral purity through the shock, vibration, and wide temperature swings of field and vehicle use. Extended temperature classes reach down to -40 °C for cold-environment deployment.
Every unit ships with the standard SpecICX-gen3 measurement suite: channel power, OBW, X dB bandwidth, harmonic measurement, SEM, AM/FM demodulation, and automatic phase noise analysis, plus spectrum, spectrogram, and historical trace views.
Highly compatible API interfaces support mainstream programming languages including C/C++, C#, Python, MATLAB, Qt, and LabVIEW on Windows and Linux. That makes secondary development straightforward and integration into larger systems clean. Talk to a Berkeley Nucleonics engineer about matching the right model to your application.

4Operating Modes
The ICX-FieldHawk offers main operating modes including Standard Spectrum Analysis, IQ Streaming, Power Detection, Real-Time Spectrum, Phase Noise Measurement, and Harmonics Analysis. Digital Demodulation is available as an option.
Standard Spectrum Analysis
This mode provides a wide range of measurement functions, including full-span spectrum sweep, channel power, OBW, ACPR, IM3, and SEM. It also supports spectrum recording and playback. Combined with auxiliary tools such as signal tracking, peak table, and amplitude correction, it delivers a one-stop platform for comprehensive spectrum check.
IQ Streaming Analysis
This mode supports up to 100 MHz analysis bandwidth and allows IQ data acquisition through multiple trigger methods. It provides IQ time-domain waveform display, spectrum and spectrogram views, AM/FM demodulation, and digital down-conversion (DDC).
Power Detection Analysis
This mode enables detection and analysis of time-domain signals within the analysis bandwidth. It suits applications focused on in-band power-versus-time relationships, such as pulse signal measurements.
Real-Time Spectrum Analysis
This mode is powered by a high-speed FPGA-based FFT engine. With strictly gapless and overlap-free FFT, it achieves true real-time monitoring across the full bandwidth.
Digital Demodulation (option)
This mode supports 2ASK, 2FSK, 4FSK, GMSK, BPSK, QPSK, 8PSK, 16QAM, 64QAM, 128QAM, and 256QAM signals.
Harmonics Analysis
This mode supports detection and measurement of up to 10 harmonic components, including harmonic peaks, harmonic channel power, and total harmonic distortion.
Phase Noise Measurement
This mode supports offset ranges from 1 Hz to 10 MHz for evaluating carrier phase stability. With the built-in automatic carrier search function, the software can quickly locate the target carrier without manual adjustment.
5Main Functions
A standard set of measurement and utility functions runs on every ICX-FieldHawk. Pulse Detection and digital demodulation are software options.
