Frequently Asked Questions (FAQs)

What is a spectrum analyzer and what is it used for?

A spectrum analyzer is a specialized device that allows you to visualize and measure radio frequency signals circulating in the environment. Its main function is to detect hidden transmitters, identify interference, and analyze the behavior of the electromagnetic spectrum. It is a key tool in security audits, technical investigations, and wireless network maintenance. Thanks to its precision, it can locate spying devices and detect suspicious emissions, even on uncommon frequencies. Its use extends from the professional field of telecommunications to counterintelligence tasks in critical environments.

How does a spectrum analyzer work in electronic security?

A spectrum analyzer captures and displays active radio frequency signals within a specific range. This allows for the identification of hidden transmissions, such as those emitted by spy microphones, wireless cameras, or GPS trackers. In electronic security, these devices are used to detect invisible threats operating via RF. They analyze the intensity, frequency, and behavior of each signal in real time, facilitating precise location of the source. They can also record activity history for subsequent audits or investigations.

Who needs to use a spectrum analyzer?

This type of equipment is recommended for professionals and organizations that need to monitor the use of the electromagnetic spectrum in their facilities. It is very useful for companies, law enforcement agencies, government institutions, telecommunications technicians, and cybersecurity consultants. It is also used by researchers, engineers, and TSCM (Technical Counterintelligence Measures) specialists. Even some individuals can benefit from it if they want to protect their privacy from spying devices. The versatility of the spectrum analyzer makes it an essential tool in sensitive environments.

What types of threats can a spectrum analyzer detect?

This device can detect unauthorized emissions such as wireless microphones, spy cameras with WiFi or GSM transmission, hidden transmitters, and GPS trackers. It also detects interference that could compromise WiFi or Bluetooth networks, assessing the integrity of the electromagnetic environment. The most advanced analyzers are capable of identifying encrypted digital signals or dynamically changing frequencies, making them difficult to detect using traditional methods. Thanks to their precision, they can classify suspicious signals and differentiate them from legitimate emissions, providing a clear view of the radio frequency environment.

Can a spectrum analyzer find powered-off devices?

No. A spectrum analyzer only detects active signals, that is, those being emitted by powered-on devices. If a transmitter is off or in passive mode, it will not generate any signals that can be identified by this type of equipment. To detect powered-off electronic devices, such as inactive cameras or microphones, it is necessary to use other devices such as nonlinear junction detectors (NLJDs), which detect the presence of electronic components even if they are not emitting any signal.

What frequency ranges do spectrum analyzers cover?

Ranges vary by model, but most professional analyzers cover frequencies from low, in the MHz range, up to several GHz. This allows them to detect signals in bands used by GSM, WiFi, Bluetooth, UHF, VHF, LTE, or even 5G systems. Some specialized models offer the option to analyze digital, encrypted, or modulated signals, making it easier to identify advanced transmissions. The range's width determines their effectiveness in locating modern spy devices operating on unconventional frequencies.

What is the difference between a spectrum analyzer and an RF detector?

A radio frequency (RF) detector alerts you to the presence of a signal using basic indicators, without providing technical details. In contrast, a spectrum analyzer displays the shape, frequency, power, and intensity of detected signals on screen. This display allows for precise identification of the source, behavior, and type of transmission. While the RF detector is useful for quick inspections, the analyzer provides a comprehensive analysis, ideal for professional electronic security tasks or advanced wireless network maintenance.

Is it easy to use a spectrum analyzer?

Portable models are designed to be easy to use, even for users without technical experience. They feature intuitive displays, automatic scanning modes, signal filters, and visual or audible alerts. However, advanced models require more technical knowledge to properly interpret spectrum data and apply customized settings. In any case, at ESPIAMOS® we offer technical advice to help you select and learn how to operate the most appropriate equipment for your level and needs.
