RF Explorer WSUB1G+ SLIM Analyser 50kHz-960MHz

RF Explorer WSUB1G Plus Slim Spectrum Analyser (50 kHz to 960 MHz) - Local Australian Stock

The RF Explorer WSUB1G Plus Slim is a high-performance digital handheld spectrum analyser engineered specifically for monitoring, diagnosing, and optimising radio frequency signals across the sub-1 GHz spectrum. Defined internationally by the ITU, sub-1 GHz Industrial, Scientific, and Medical (ISM) frequency allocations (including 433 MHz, 868 MHz, and 915 MHz) are licence-exempt bands used extensively for short-range wireless devices, Internet of Things (IoT) hardware, smart utility metering, remote controls, medical sensors, and telemetry. Because these shared bands operate without individual broadcast licences, they are heavily congested and prone to severe radio frequency interference (RFI) and co-channel noise. The WSUB1G Plus Slim provides a dedicated, highly cost-effective spectrum analysis tool focused entirely on sub-1 GHz frequencies, making it the ideal choice for field technicians, wireless installers, and radio amateurs who do not require higher microwave band coverage.

Covering a continuous frequency span from 50 kHz up to 960 MHz (spanning LF, MF, HF, VHF, and UHF bands), this upgraded PLUS Slim model delivers enhanced LNA sensitivity, an internal 30 dB attenuator, and an internal expansion slot for future module additions. Enclosed in a heavy-duty SLIM solid aluminium chassis with a high-capacity 1800 mAh internal rechargeable Lithium-Ion battery providing over 16 hours of continuous field operation, it serves as an essential portable instrument for wireless site surveys, interference hunting, and RF workshop testing. When connected to a PC or Mac via USB, it pairs with free open-source RF Explorer software for real-time spectrum monitoring, waterfall displays, data logging, and signal analysis.

Applications & Practical Uses:

• Sub-1 GHz ISM Band & Unlicenced Wireless Analysis: Dedicated spectrum monitoring across popular licence-exempt ISM bands (433 MHz, 868 MHz, and 915 MHz). Instantly identify signal occupancy, measure channel utilisation, and troubleshoot unlicenced devices including LoRaWAN gateways, smart utility meters, RFID readers, garage door controls, wireless weather sensors, and industrial telemetry systems.
• Wideband RF Spectrum Sweeping (50 kHz to 960 MHz): Continuous real-time sweeps across LF, MF, HF, VHF, and UHF spectrum. Detect unwanted signals, stray radiation, and rogue transmissions across AM/FM radio, digital TV (DTV), cellular networks, and wireless audio setups.
• Amateur Radio (HAM) Band Alignment: Essential portable analysis tool for HAM radio operators covering all popular sub-1 GHz HAM bands from 160 metres up to 33 cm (1.8 MHz to 902 - 928 MHz). Helps align antennas, test transmitter output, check spurious harmonic emissions, and monitor band activity in real time.
• Interference Hunting & RFI Tracking: Rapidly track down intermittent radio frequency interference (RFI), electrical noise spikes, or unlicenced stray transmissions. Utilise real-time peak hold, averaging, and waterfall modes alongside directional or near-field antennas to trace signal leakage and EMI noise from unshielded electronics.
• EMC & EMI Pre-Compliance Testing: Conduct preliminary Electromagnetic Compatibility (EMC) and Electromagnetic Interference (EMI) sweeps on prototype circuit boards (PCBs), cable harnesses, and shielded enclosures prior to formal laboratory testing. Identify board-level radiation and harmonic spikes early in the development cycle to avoid expensive lab re-testing.
• RF Field Exposure & Wireless Site Auditing: Audit ambient radio frequency field strengths around wireless telemetry units, remote control transmitters, broadcast towers, and industrial high-frequency machinery to confirm compliance with safety exposure guidelines and verify link coverage.

Key Features & Highlights:

• Sub-1 GHz Wideband Coverage: Covers a continuous range from 50 kHz to 960 MHz spanning LF, MF, HF, VHF, and UHF spectrum with zero frequency gaps.
• SLIM Aluminium Chassis: Heavy-duty solid metal enclosure featuring an ergonomic side USB port and physical HELP and SET buttons for simplified two-click menu navigation and configuration adjustments.
• Built-in LNA & Attenuator: Features a selectable internal Low Noise Amplifier (+25 dB gain) and a 30 dB internal attenuator for handling sensitive low-level signals as well as higher input power levels.
• Modular Hardware Expandability: Built with an internal expansion slot, allowing easy hardware upgrades with RF Explorer expansion modules to add higher frequency bands and functionality in the future.
• High-Capacity Battery: Internal 1800 mAh rechargeable Lithium-Ion battery provides over 16 hours of continuous field operation on a single USB charge.
• Multi-Mode Spectrum Analysis: Supports Peak Max & Hold, Normal, Overwrite, and Averaging display modes with automatic Resolution Bandwidth (RBW) scaling.
• Cross-Platform Compatibility: Fully supported on Windows, Linux, and macOS via free open-source desktop applications and developer API libraries.

Protection Note:
RF Explorer is a highly sensitive spectrum analyser designed primarily for over-the-air signal detection using an aerial antenna. When connecting directly to an active signal source using a coaxial cable, always use an RF Power Limiter or inline attenuator to protect the sensitive input front-end from overload damage.
