What is the difference between versions of the Delta X?
The Delta X system has two primary versions: the Delta X G2/6 and the Delta X G2/12. The difference lies strictly in their frequency range and hardware configuration. The G2/6 operates within a frequency range of 9 kHz to 6000 MHz. The G2/12 operates from 9 kHz to 12000 MHz. To support this extended range, the G2/12 version includes an additional AUX2 antenna input and is supplied with the LPDA-12 directed microwave antenna.
What does the “speed of detection” mean?
The manual defines this concept pragmatically through “sweeping speed” and “update time” metrics. Sweeping speed dictates how fast the spectrum analyzer scans the frequency range, reaching up to 11 GHz per second depending on the hardware and active features like Burst Hunt. The update time represents the duration required to complete a single sweep in the currently active searching mode. A faster update time (shorter measurement interval) increases the speed and probability of detecting short-burst signals.
How does the Delta X warn about the detected danger?
The system utilizes multiple methods to alert the operator when a signal exceeds the defined threshold:
- Bargraphs on the “Level” panel change color from green to red.
- An audio alarm produces a warning sound that increases in intensity as the signal level rises.
- Dangerous signals are visually marked on the spectrum graph using the “Threat Mark” feature.
- The “Hold maximum danger” feature automatically tunes to and displays the most dangerous band or signal.
- An alarm indicator is present on the front hardware panel.
- An alarm relay output can trigger external devices upon detection.
When should I use the omnidirectional and when – the directional microwave antenna?
The ODA-4 omnidirectional antenna features a wide frequency range and circular sensitivity, making it suitable for all searching modes, including the “All signals” mode. The MWA-6 directional microwave antenna provides increased sensitivity and a longer detection distance on the upper parts of the spectrum. You must use the MWA-6 for scanning mobile and wireless signals in the “Mobile/GPS trackers” and “Wireless/ISM” modes. It is also required when inspecting large objects like trucks for trackers to provide an extended detection diagram. Additionally, the MWA-6 speeds up the locating process by allowing the operator to point in the direction of the transmitter.
What laptop should I purchase to use with the Delta X?
The hardware must meet specific configuration demands because the system performs high-speed data transfers and requires significant processing power. The requirements are:
- Processor: Intel Core i3 / AMD Ryzen 3 or better, with Intel Core i5 / AMD Ryzen 5 recommended.
- USB Ports: Two ports, one of which must be a SuperSpeed type (USB 3.0/3.1/3.2 or USB Type C).
- RAM: 8 GB or more.
- Storage: SSD with 128 GB or more.
- OS: Windows 10, 11, or newer.
- Screen: 12-14 inches.
How to guard the area 24/7?
The Delta X can conduct long-term radio monitoring of the RF environment 24 hours a day by logging all data to the computer’s SSD. To initiate this, start the desired searching mode and activate the “Perform logging” function so the button remains in the pressed state. This ensures spectrum traces and alarm events are continuously recorded into an unlimited number of logs. If you plan to monitor without moving the system, you must lower the thresholds to increase the detection distance.
What is the distance of detection should I expect?
The detection distance correlates directly with the threshold level configured by the operator and the power of the transmitter. A lower threshold increases the distance, while a higher threshold decreases it. For an average mobile or Wi-Fi signal, the approximate detection distances based on the threshold are: 5-20 meters at -80 dBm, 4-10 meters at -70 dBm, 3-8 meters at -60 dBm, 2-5 meters at -50 dBm, 1-3 meters at -40 dBm, and less than 2 meters at -30 dBm.
How the detected signals are placed on the Locator? Can I see the direction to the transmitter?
The provided manual does not contain information regarding a “Locator” feature. However, you can determine the direction to the transmitter manually during the physical search. By moving or rotating the system and utilizing the MWA-6 directional antenna, you can find the direction of the signal by identifying where the signal level is at its maximum. The bargraphs and audio alarm intensity will guide you toward the source as the level increases.
Shall I perform the Update Masks procedure before each sweeping?
Masking the background is strictly required only before using the “All signals” and “Downlinks/Navigation” searching modes. It allows the system to exclude safe external background signals, such as TV and radio broadcasting, and focus on local threats. This procedure must be performed at a distance of at least 10 meters away from the target zone. Background masking is not required when searching in the “Mobile/GPS trackers” and “Wireless/ISM” modes.
