Delta S RF Scanning System for Professional Counter-Surveillance

The Delta S is a professional RF scanning system developed for detecting and analyzing hidden transmitters across a wide frequency spectrum. Covering 60 MHz to 6 GHz, it is designed to help security professionals identify and localize a broad range of RF-based surveillance and interference threats in controlled, corporate, institutional, and high-risk environments.

This system is built to detect analog and digital transmissions, including signals that are continuous or intermittent, encrypted or unencrypted. It supports the detection of widely used wireless standards such as GSM, 3G, 4G/LTE, 5G, Wi-Fi, Bluetooth, DECT, ZigBee, and LoRa, while also helping locate RF jammers and analog devices operating in VHF/UHF bands. For teams responsible for protecting communications, sensitive spaces, or operational continuity, the Delta S provides a structured and highly capable RF inspection platform.

Wideband Detection Coverage from 60 MHz to 6 GHz

One of the Delta S system’s main strengths is its wide frequency range. With coverage from 60 MHz up to 6 GHz, it is suitable for scanning many of the bands used by modern wireless devices and surveillance transmitters. This broad range allows operators to inspect environments for multiple categories of RF activity without relying on a narrow-band detector.

The system is intended to detect:

• Mobile network transmissions, including GSM, 3G, 4G/LTE, and 5G

• Wireless protocols such as Wi-Fi, Bluetooth, DECT, ZigBee, and LoRa

• Analog surveillance devices in VHF and UHF bands

• RF jammers affecting mobile, satellite, GPS, Wi-Fi, or Bluetooth signals

This makes the Delta S especially relevant where a full-spectrum RF review is required rather than a basic signal presence check.

Dedicated Analysis for Wi-Fi, Bluetooth, Cellular Signals, and Jammers

The Delta S is not limited to broad scanning alone. It also includes targeted analysis functions for common modern wireless technologies. In particular, it can scan the 2.4 GHz and 5 GHz bands and detect Bluetooth LE and Bluetooth Advertising, which is important when assessing environments where short-range wireless devices may be active.

Its jammer detection capability is another important operational benefit. The system can locate RF jammers targeting mobile, satellite, GPS, Wi-Fi, or Bluetooth signals. In environments where communications integrity matters, being able to identify interference sources quickly can be just as important as locating unauthorized transmitters.

Flexible Scanning Modes for Different Inspection Tasks

The Delta S includes several scanning modes that help adapt the system to different RF inspection objectives. These modes allow the operator to focus on broad-spectrum activity or on specific categories of transmission depending on the environment and the type of threat being investigated.

All Signals Mode

This mode performs a full-spectrum scan from 60 MHz to 6 GHz. It is suitable when a complete RF overview is required and when the operator wants to assess all detectable activity across the supported range.

GPS Tracker Detection

This mode is designed to recognize GSM, 3G, 4G, and 5G-based tracking devices. It is useful when the inspection objective includes identifying cellular-based location transmitters.

Wireless / ISM Mode

This mode targets Wi-Fi, Bluetooth, and ZigBee devices. It is particularly relevant in offices, meeting rooms, technical spaces, and other environments where short-range wireless activity needs closer review.

Downlink & Navigation Mode

This mode analyzes cellular and satellite downlinks and can detect GPS jammers. It supports inspections where navigation or communication interference is a concern.

Real-Time Monitoring and Intelligent Signal Filtering

In active RF environments, one of the main challenges is separating meaningful local threats from normal background transmissions. The Delta S addresses this with background signal masking, which helps ignore known ambient signals such as TV, radio, and cell tower transmissions. This allows the operator to focus more effectively on local RF activity that may require attention.

The system also supports live RF monitoring with 24/7 tracking, full event logging, and unlimited data history. For professional users, this is valuable when inspections need to move beyond a one-time sweep and into longer-term observation of an environment.

Additional monitoring support includes:

• Automatic signal recognition for fast identification of notable transmissions

• Instant spectral feedback to help visualize signal activity in real time

• Audible alerts based on signal intensity to assist with quick localization

These functions help make the Delta S practical not only for analysis but also for active fieldwork where speed and clarity matter.

Detailed Band Inspection and Signal Analysis

The Delta S is designed to provide more than a simple alert. It enables inspection of individual frequency bands using key metrics such as current dB level, maximum detected level, and the number of threat signals. This gives operators a clearer understanding of what is happening within a selected portion of the spectrum.

The system also allows users to analyze signal lists and trace specific emitters with high accuracy. For professional counter-surveillance and RF assessment work, this level of detail is important because it supports a more methodical and evidence-based inspection process.

Special Detection Functions

The Delta S includes several dedicated functions that support more precise RF threat detection and signal handling.

Threat Mark

Threat Mark visually highlights dangerous signals on the spectrum graph, helping the operator identify suspicious activity more quickly during analysis.

Burst Hunt

Burst Hunt is designed to detect short burst signals, including those associated with Wi-Fi, Bluetooth, and 5G. This is especially useful when dealing with transmissions that are not continuously active.

Attenuator

The built-in attenuator helps isolate strong nearby transmitters. This can improve inspection control in signal-dense environments where dominant sources may otherwise complicate analysis.

RF Jammer Detection

The system can identify interference sources across all bands, supporting investigations into intentional or disruptive RF interference.

Portable Design for Field Use

Although it is a professional-grade system, the Delta S is designed with mobility in mind. It can mount directly to a laptop or tablet using a magnetic docking system, creating a compact and practical setup for field inspections.

Its physical design also includes side handles for more comfortable handling and secure antenna positioning. For transport and protection, the system comes with a durable transport case.

The dual-antenna configuration covers 60–2000 MHz and 2000–6000 MHz, supporting full-range sensitivity across the device’s operating spectrum.
