ICX-FieldHawk-U / ICX-FieldHawk-N Product Manual

Branding and verification notes. This Product Manual is rebranded from a third-party SAN/SAM/NXN/NXM series source manual. The following assumptions were applied. Please confirm before publication.

Model mapping. The numeric part of each model is the source model number (frequency-derived) and is preserved, zero-padded to three digits. USB models (source SAN / SAM) map to the ICX-FieldHawk-U line with a U suffix. Networked / Ethernet models (source NXN / NXM) map to the ICX-FieldHawk-N line with a proposed N suffix. The economy tier carries no extra mark; the performance tier (source SAM / NXM) carries a -P performance designation, for example ICX-060U-P. The "-N" networked suffix and the "-P" performance designation are proposed conventions. verify.
Firmware rename. The source control software is renamed throughout to SpecICX-gen3, Berkeley Nucleonics' spectrum analysis firmware. Described functionality is unchanged.
Antenna accessories. External antennas are presented as accessories, not options, drawn from the ANT-100G / ANT-200G family. Confirm the part number. verify.
Specifications. All spec values are reproduced identically from the source for the same hardware. Tables were lightly regrouped for readability. Values remain preliminary pending verification against the published BNC datasheet. verify.
In-firmware branding. The SpecICX-gen3 screenshots in sections 2 and 3 are sourced from the original application. The vendor wordmark has been masked and relabeled to SpecICX-gen3. Recapture with the production BNC build before publication. verify.

1Overview

ICX-FieldHawk-U and ICX-FieldHawk-N real-time spectrum analyzers — Figure 1-1. ICX-FieldHawk-U USB and ICX-FieldHawk-N networked real-time spectrum analyzers.

The ICX-FieldHawk-U and ICX-FieldHawk-N families are compact real-time spectrum analyzers that deliver excellent RF performance while holding cost down. Their miniaturized design integrates easily into automated test systems and preserves spectral purity, which makes them well suited to space- and cost-constrained applications where a full benchtop instrument would be impractical. The result is well-balanced performance, cost, and size across a wide range of models.

USB and Ethernet connectivity

The two lines differ in how they connect to the host. The ICX-FieldHawk-U line (USB) supports USB 3.0 and USB 2.0 over a single Type-C interface. The ICX-FieldHawk-N line (networked) connects over Ethernet and is compatible with 1000M and 100M networks. Beyond the host interface, the two lines are functionally aligned.

A wide range of models

The economy tier (the ICX-FieldHawk-U and ICX-FieldHawk-N base models) focuses on cost efficiency, with three frequency options: 4.5 GHz, 6.3 GHz, and 40 GHz. The performance tier (the -P designation) prioritizes RF performance, with 6.3 GHz and 8.5 GHz options. The combination of interface type, frequency range, and cost tier gives you a fully optimized choice for a wide variety of applications.

Unified API

Every series and model shares one consistent API. You can migrate between units, or from USB to Ethernet, without changing application code. Development is supported in C/C++, C#, Python, MATLAB, Qt, and LabVIEW, on both Windows and Linux.

Rich standard measurement functions

A rich set of advanced measurements ships as standard, including channel power, occupied bandwidth, X dB bandwidth, harmonic measurement, spectrum emission mask (SEM), AM and FM demodulation, and automatic phase noise analysis.

2Operating Modes

SpecICX-gen3, Berkeley Nucleonics' spectrum analysis firmware, offers seven main operating modes: Standard Spectrum Analysis, IQ Streaming, Power Detection Analysis, Real-Time Spectrum Analysis, Phase Noise Measurement, Digital Demodulation (option), and Harmonics Analysis. Each mode reuses the same acquisition hardware, so switching between them takes no rewiring.

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, the peak table, and amplitude correction, it gives you a one-stop platform for thorough spectrum inspection.

IQ Streaming

This mode supports up to 100 MHz of analysis bandwidth and acquires IQ data through multiple trigger methods. It provides IQ time-domain waveform display, spectrum and spectrogram views, AM and FM demodulation, and digital down conversion (DDC).

Power Detection Analysis

This mode detects and analyzes time-domain signals within the analysis bandwidth. It suits applications focused on in-band power versus time, such as pulse signal measurement.

Real-Time Spectrum Analysis

This mode is powered by a high-speed FPGA-based FFT engine. The FFT is strictly gapless and overlap-free, which delivers true real-time monitoring across the full bandwidth with no missing samples between frames.

Digital Demodulation (option)

This mode supports 2ASK, 2FSK, 4FSK, GMSK, BPSK, QPSK, 8PSK, 16QAM, 64QAM, 128QAM, and 256QAM signals.

SpecICX-gen3 screenshot: Digital Demodulation mode — Figure 2-5. Digital Demodulation mode in SpecICX-gen3.

Harmonics Analysis

This mode detects and measures 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. A built-in automatic carrier search locates the target carrier quickly, with no manual adjustment.

17Model Selection

The ICX-FieldHawk-U (USB) and ICX-FieldHawk-N (networked) lines share the same measurement engine and firmware. Choose the interface that fits your host, the frequency ceiling your work demands, and the economy or performance tier. The networked line adds AArch64 support and internal GNSS.
