Delta X G2/6 RF Signal Detector and Counter-Surveillance Device

The Delta X G2/6 is a portable, laptop-controlled counter-surveillance system designed for professional RF detection, signal analysis, and long-duration monitoring. Covering a wide frequency range from 9 kHz to 6 GHz, it is built to detect hidden wireless transmitters, suspicious RF activity, and unauthorized signal leakage in demanding inspection environments.

This system is intended for legitimate security, safety, and technical surveillance countermeasure work. It can detect a broad range of RF listening devices, whether analog or digital, continuous or intermittent, and whether they transmit audio or video. It is also designed to identify devices operating on common wireless standards including GSM, 3G, 4G/LTE, 5G below 6 GHz, Bluetooth, Wi-Fi, and DECT.

Built for modern counter-surveillance work

What sets the Delta X G2/6 apart is its ability to combine real-time spectrum analysis with practical field usability. Short-burst transmissions such as Wi-Fi, Bluetooth, and mobile signals can be detected in just seconds, helping operators identify activity that may be missed by simpler detectors. The system also supports signal accumulation, allowing it to detect bugging devices that transmit briefly or remain masked by surrounding RF activity.

An automatic antenna selection system helps maintain optimal sensitivity across different bands, while the software environment provides visual tools such as spectrogram, persistence, waterfall, and alerts for clearer interpretation of the RF landscape.

Multiple operating modes for different inspection tasks

The Delta X G2/6 supports several dedicated operating modes to match different workflows and environments. These include:

• Main RF Sweep Mode for maximum sensitivity during active scanning
• 24/7 Guard Mode for continuous monitoring with a low false alert rate
• Vehicle GPS Tracker Detection for scanning mobile bands to find trackers transmitting via 3G/4G
• Probe Mode for detecting hidden transmissions in AC lines, Ethernet, telephone cables, and infrared paths
• Signal Analysis for locating and demodulating active transmissions
• Detection Log Review for examining past detections and alerts
• Mask Update for preparing the system for a specific RF environment
• Configuration Mode for adapting thresholds and known frequencies to local conditions

This range of modes makes the unit suitable for both rapid sweeps and more methodical, evidence-based monitoring over time.

Detection beyond standard wireless signals

In addition to RF detection, the included multifunctional probe extends the system’s capabilities to identify unauthorized data transmission through physical infrastructure. According to the supplied specifications, the Delta X G2/6 can detect suspicious transmissions through AC power lines, telephone cables, Ethernet, alarm systems, and infrared.

This is particularly valuable in environments where threats may not rely solely on conventional over-the-air transmission. For professional inspections, this broader detection scope can help reduce blind spots and improve confidence in the final assessment.

High sensitivity and fast response

The manufacturer states that the Delta X G2/6 offers 20 to 50 times more sensitivity and range than conventional RF detectors. It is designed to remain highly sensitive even in challenging RF environments near routers, towers, or mobile phones. Combined with a sweep speed of 2 to 3 GHz per second and a response time of 2 to 3 seconds, the system is built for fast, high-precision detection work.

The device also uses a threat evaluation approach based on reference traces, individual thresholds, signal strength, and bandwidth. This helps distinguish between safe and potentially dangerous signals more effectively than methods based only on raw signal strength.

Advanced software for analysis and reporting

The Delta X software is designed to support both live investigations and post-inspection review. It provides:

• Real-time notifications to guide the operator during bug localization
• Alarm thresholds to minimize false positives
• Hold Max Danger to highlight the strongest threats while scanning
• Mask update to adapt quickly to the local RF environment
• Sorting and filtering in signal logs
• Exportable full signal reports
• Multilingual software

The system also supports a Known Signals table that helps exclude safe signals and improve focus on unknown or suspicious activity. Operators can import known TV, FM, and public frequency bands, and store local reference frequencies for more efficient analysis.

Continuous monitoring and unlimited logging

For long-term protection tasks, the Delta X G2/6 supports 24/7 RF environment monitoring with unlimited data recording and unlimited signal storage. All traces and alerts are logged in detail for later review, making the system suitable for detecting intermittent, scheduled, or remote-controlled transmissions that may not appear during a short manual sweep.

Signal history can be reviewed through intuitive charts, helping the operator visualize activity duration and compare suspicious events against normal interference. Customizable time intervals from 2 minutes to 6 hours provide flexibility when reviewing patterns over time.

The stated 24-hour storage requirement is under 12 GB, which helps in planning long-duration monitoring sessions on a compatible laptop or tablet.

Portable design for field deployment

The Delta X G2/6 is an evolution of the Delta X 100 and is designed for mobility during inspections. Its portable format, side handles, and magnetic mount for a laptop or tablet support easier movement while scanning and tracking signals. All antennas attach directly to the main unit, helping keep the setup organized in the field.

The unit dimensions without antennas are 33.5 x 26 x 6 cm, and the weight without a laptop or tablet is 3.4 kg. It is powered via USB from a laptop or tablet, which simplifies deployment without requiring a separate power arrangement in the supplied description.

Audio demodulation and signal review

For active transmission analysis, the Delta X G2/6 supports audio demodulation in FM, AM, USB, LSB, and CW modes. Adjustable bandwidths from 3 to 240 kHz provide flexibility when examining different signal types. This can assist trained operators during localization and technical assessment of detected transmissions.

The display and analysis environment includes data views such as Live, Max, Persistence, and Threshold, along with graph formats including Spectrogram and Waterfall. The display range is specified as -90 to -10 dBm, and the spectral resolution is 9.8 kHz.
