What is a Spectrum Analyzer

A RF Explorer Spectrum Analyzer is a specialized device that can detect highly sensitive signal radiation, identify signal interference, optimize antenna settings, detect signal leakage, and locate hidden bugs, among other capabilities. The combination of small size, high sensitivity, and rugged design makes it the ideal instrument for indoor and outdoor measurements. When linked to a computer, it may be controlled by a free software that includes high-resolution images, data storage, and reply features.

When linked to a PC, the RF Explorer provides enhanced capabilities. Its multi-platform software, along with its API libraries, is open-source and supports Windows, Linux, and MacOS X operating systems. This ensures flexibility and accessibility across different platforms. The software is available for free download.

Who Utilizes a RF Explorer?

RF Explorer is a versatile device used by a wide range of professionals and enthusiasts in various fields. Some of the key users include:

  1. Radio Frequency (RF) Engineers: RF Engineers use RF Explorer devices for spectrum analysis, signal monitoring, troubleshooting in telecommunications, wireless networking, and radio frequency design.

  2. Radio Operators: Ham radio operators utilize RF Explorer devices for frequency analysis, antenna tuning, and monitoring radio spectrum activity.

  3. Education and Research: RF Explorer devices can be used in academic institutions and research laboratories for teaching RF principles, conducting experiments, and analyzing electromagnetic spectrum characteristics.

  4. Audio and Video Production: RF Explorer devices are used by professionals in audio and video production to scan for available frequencies, avoid interference, coordinate wireless microphone systems and other wireless audio/video equipment.


RF Explorer Application

Wireless Network Analysis

The RF Explorer can be used to analyze Wi-Fi networks, discover signal strength, channel congestion, and interference sources. This is beneficial for improving Wi-Fi performance in congested areas or diagnosing connectivity difficulties.

RF Emission Compliance Testing

The RF Explorer can be used for basic RF emission compliance testing to ensure that electronic devices comply with regulatory standards for electromagnetic interference (EMI). This is particularly relevant for manufacturers or developers of electronic products.

RF Spectrum Monitoring

RF Explorer devices can be used for general RF spectrum monitoring, allowing you to detect and analyze various signals in the environment. This is valuable for identifying unauthorized transmissions, detecting interference, or monitoring for potential security threats.

SLIM Holder

This custom-made, high-quality holder is an ideal addition to your RF Explorer SLIM model, offering both protection and pleasant viewing angles at the workplace.



Near Field Antenna Kit

The RF Explorer Near Field Antenna Kit consists of four high-performance antennas suited for the most demanding RF diagnosis tasks:

RFEAH-25: H-Loop magnetic 25mm diameter
RFEAH-15: H-Loop magnetic 15mm diameter
RFEAH-5: H-Loop magnetic 5mm diameter
RFEAE-10: E-Field stub 10mm length

Power Limiter

All RF Explorer devices have input signal power ranges that might cause damage. Most models have a limit of +5dBm, while some can handle up to +10dBm, but only the WSUB3G (as well as the RF SMA connection on the right side of a 3G Combo) is protected up to +30dBm.
