Spectrum analyzer

A unique feature of this category of instruments is their high sensitivity and resolution. This feature makes them an irreplaceable tool for professional surveys of premises for wiretapping. Their sensitivity is many times higher than that of traditional near-field receivers. TSCM specialists around the world use a set of detection equipment when performing surveys, including the non-linear junction detector, near-field receiver, thermal vision, tools for physical search, etc. The spectrum analyzer is the most important tool. It covers a wide frequency range, has a high sensitivity and is capable of detecting all RF signals, including hidden radio frequency transmitters, wireless signals, hidden cameras, radio microphones, GPS trackers, etc. including both analog and digital sources, such as IP devices. For example, the OSCOR GREEN system has gained popularity due to a wide range of frequencies, portability and sensitivity. Its high speed of measurement and the ability to locate the transmitter are its indisputable advantages. A fairly high price and high demands on the operator's level of knowledge could be attributed to its shortcomings.

The most important requirements for a professional signal analyzer

• The ability to detect a large number of signals simultaneously
• The ability to filter/mask safe broadcast signals
• Assignment of a high level of danger to local dangerous signals
• A high detection distance of the transmitter, 10-20 times the range of a conventional RF signal detector
• Accumulation of known friendly signals such as FM radio and HD Radio, analog television, digital television, radio communications of police, military and other services
• Event logging, allowing subsequent analysis of detected signals and their activity
• Detection of wireless surveillance system and IP-devices
• 24 hour security operation with full data logging
• Autonomous power supply with a resource of at least 1-2 hours
• Immunity to interference – neighboring wireless devices, cordless phones, mobile phones and cellular towers should not decrease the general sensitivity
• The presence of counter surveillance features such as the possibility to locate the bugging transmitter physically, warn the operator with an alarm, or switch on an external security system using the relay output
• A high level of representation - spectrogram, persistence, waterfall, alarm graph, etc. and possibilities to scroll, zoom in/out, set arbitrary displayed span and export the images.

Other desired features of the professional electronic detecting device

The detecting system can be used in a portable version and while stationary. In the fixed installation, its sensitivity must cover the target zone. This is achieved by placing the antenna in the center of the room, or in the area of negotiations, for example, near the table. In this case, even the weakest signals such as Bluetooth can be instantly detected.

A wireless surveillance system can use different types of modulation for signal transmission, so the detection device should be able to detect any kind of modulation, including the modern digital standards, such as LTE/4G, 3G, 4G/LTE, 5G(<6GHz), GSM, Wi-Fi, etc.
