Today, Signal Hound’s spectrum analyzer lineup stands as a testament to this mission, covering a full range of frequency bands from 9 kHz to 43.5 GHz and offering versatile solutions for lab testing, field troubleshooting, industrial automation, and cutting-edge 5G/millimeter-wave research. Whether you’re a seasoned RF professional or just starting your journey, Signal Hound has a spectrum analyzer tailored to your unique needs.

A Comprehensive Product Lineup for Every Frequency and Application

Signal Hound’s spectrum analyzers are designed to span low, mid, and high-frequency ranges, ensuring there’s a perfect match for every use case—from basic IoT device testing to advanced millimeter-wave analysis. The core product series includes:

1. Entry-Level USB-Powered Series: SA44B & SA124B

Ideal for budget-conscious users and entry-level RF applications, the SA44B and SA124B are compact, USB-powered spectrum analyzers that deliver exceptional value without sacrificing essential functionality. With frequency ranges of 9 kHz to 6.0 GHz (SA44B) and 9 kHz to 12.4 GHz (SA124B), these devices are perfect for basic RF monitoring, wireless device development (e.g., Bluetooth, Zigbee), and educational purposes. Their lightweight design and USB 2.0 compatibility make them easy to integrate with any Windows or Linux PC, eliminating the need for bulky benchtop hardware and reducing upfront costs.

2. Portable Real-Time Series: BB60 Series (BB60C, BB60D)

Built for on-the-go testing and field troubleshooting, the BB60 series redefines portability and real-time performance. Covering a frequency range of 9 kHz to 6.0 GHz, models like the BB60C and BB60D offer up to 85 dB and 95 dB dynamic range respectively, enabling users to detect weak signals even in the presence of strong interference—critical for field interference hunting and network optimization. USB 3.0-powered and compatible with both Windows and Linux, these analyzers seamlessly integrate with remote control systems, allowing engineers to operate them from anywhere with network access, reducing the need for multiple on-site devices.

3. Mid-Range High-Performance Series: SM200 Series (SM200B, SM200C)

The SM200 series bridges the gap between entry-level and high-end analyzers, offering unmatched performance for mid-frequency applications (100 kHz to 20 GHz). These analyzers boast industry-leading specs, including 110 dB dynamic range, 1 THz/sec sweep speed, and 160 MHz instantaneous bandwidth—performance that rivals expensive benchtop models at a fraction of the cost. With a displayed average noise level as low as -160 dBm and phase noise of 132 dBc/Hz (10 kHz offset at 1 GHz), the SM200 series excels in 5G sub-6 GHz testing, EMC pre-compliance, and phase noise characterization. Its modular design and calibrated I/Q streaming capabilities (up to 40 MHz) make it a versatile tool for both lab and production line testing.

4. High-Frequency/Millimeter-Wave Series: SM435 Series (SM435B, SM435C) & SP145

For cutting-edge high-frequency and millimeter-wave applications, Signal Hound’s SM435 series and SP145 deliver professional-grade performance up to 43.5 GHz. The SM435 series, with its 100 kHz to 43.5 GHz frequency range, 110 dB dynamic range, and 1 THz/sec sweep speed, is engineered for 5G millimeter-wave (24 GHz, 28 GHz, 39 GHz) testing, antenna pattern measurement, and advanced spectrum monitoring. It features a 10 Gigabit Ethernet SFP+ port for long-distance communication with PCs, enabling flexible remote deployment in harsh or hard-to-reach environments. The SP145, covering 100 kHz to 14.5 GHz, adds a built-in GPS for field testing, 40 MHz continuous streaming bandwidth, and -160 dBm display average noise, making it ideal for airborne RF measurements and outdoor spectrum monitoring.

Core Advantages That Set Signal Hound Apart

What truly distinguishes Signal Hound from traditional test equipment manufacturers is its unwavering focus on user-centric innovation, cost-effectiveness, and flexibility. Key advantages include:

• Unmatched Cost-Effectiveness: Signal Hound eliminates the "brand premium" common in the industry, offering performance comparable to high-end analyzers at 30-50% lower prices. For example, the mid-range SM435 matches the real-time bandwidth and noise floor performance of premium brand millimeter-wave analyzers without the exorbitant cost, making advanced RF testing accessible to budget-constrained organizations and academic labs.

• Cross-Platform Compatibility: All Signal Hound spectrum analyzers are fully compatible with both Windows and mainstream Linux distributions (Ubuntu, RHEL), eliminating the need for dedicated proprietary PCs and reducing hidden software licensing costs. This flexibility is a boon for teams using mixed OS environments.

• Powerful, Free Spike Software: Every Signal Hound analyzer comes with Spike, the company’s flagship RF analysis software, at no additional cost. Spike offers a comprehensive suite of core features—real-time spectrum scanning, waterfall displays, interference detection, digital demodulation (ASK, FSK, PSK, QAM), and EMC pre-compliance tools—eliminating the need to purchase expensive software licenses. Optional advanced features are available for users who need them, ensuring you only pay for what you use.

• Low Total Cost of Ownership (TCO): Designed for durability and easy maintenance, Signal Hound analyzers feature a modular design that simplifies repairs. Free lifetime software updates and a standard 2-year warranty further reduce long-term costs, avoiding the expensive calibration and maintenance fees associated with high-end benchtop models.

• Flexible Deployment Options: From compact USB-powered models for lab desks to portable field units with remote control capabilities, Signal Hound analyzers adapt to any workflow. Their compatibility with remote desktop and API-based client-server systems allows a single analyzer to serve multiple users across different locations, reducing the need for duplicate equipment.
