A portable real-time spectrum analyzer in a 10.1-inch touchscreen handheld. The ICX-FieldHawk covers 9 kHz to 40 GHz across six models, delivers up to 100 MHz of gapless analysis bandwidth, and sweeps up to 1 THz/s for fast field work and lab measurement.
The Berkeley Nucleonics ICX-FieldHawk is a handheld real-time spectrum analyzer built for solid RF performance away from the bench. The series offers frequency ranges from 9 kHz up to 4.5, 6, 9, 9.5, 20, or 40 GHz and an analysis bandwidth of up to 100 MHz: the 4.5, 6, and 9 GHz models ship with 50 MHz and take a 100 MHz option, and the 9.5, 20, and 40 GHz models ship with 100 MHz. Based on a fast FFT design, the series achieves a sweep speed up to 1 THz/s.
The instrument is equipped with a 10.1-inch full touch screen and an intuitive user interface that allows smartphone-like touch gestures. It weighs around 1.5 kg for easy carry and operation in the lab or the field.
The ICX-FieldHawk comes standard with a variety of advanced measurement functions, including channel power, OBW, X dB bandwidth, harmonic measurement, SEM, AM/FM demodulation, and automatic phase noise analysis. The SpectraCore software adds spectrum, spectrogram, and historical trace views.
Highly compatible API interfaces support mainstream programming languages including C/C++, C#, Python, MATLAB, Qt, and LabVIEW. 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. On the ICX-045/060/090, Mapping mode (GPS-referenced heat maps for radio monitoring and interference analysis) is additionally standard, and EMI Pre-Compliance Measurement (opt. 74) is available as a software 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.
Standard Spectrum Analysis
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).
IQ Streaming Analysis
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.
Power Detection Analysis
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.
Real-Time Spectrum Analysis
Digital Demodulation (option)
This mode supports 2ASK, 2FSK, 4FSK, GMSK, BPSK, QPSK, 8PSK, 16QAM, 64QAM, 128QAM, and 256QAM signals.
Digital Demodulation (option)
Harmonics Analysis
This mode supports detection and measurement of up to 10 harmonic components, including harmonic peaks, harmonic channel power, and total harmonic distortion.
Harmonics Analysis
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.
