EDD-24XT Portable Non Linear Junction Detector

The EDD-24XT is a portable Non-Linear Junction Detector or ‘NLJD’ designed specifically for professional countermeasures use (TSCM). It will detect the presence of semiconductor circuits that are used in all modern electronic devices such as mobile phones, tracking devices, listening devices, covert cameras, digital voice recorders, SIM cards etc. Importantly, the EDD-24XT will detect such devices whether they are switched on and in use, powered on but in standby mode, or even switched off without any power. The EDD-24XT is supplied with an adjustable aluminium extension pole that enables the length to be set anywhere between 30cm and 140cm, enabling the user to reach higher, hard to reach areas. The EDD-24T is a compact handheld Non Linear Junction Detector or NLJD. It will detect the presence of semiconductor circuits that are used in all modern electronic devices such as mobile phones, tracking devices, listening devices, covert cameras, digital voice recorders, SIM cards etc. Importantly, the EDD-24T will detect such devices whether they are switched on and in use, powered on but in standby mode, or even switched off without any power. Principle of operation Semiconductor Electronics are used in all modern electronics and are made using Silicon. When high frequency radio signals are transmitted directly over silicon they produce a strong second (2nd) harmonic frequency of that radio signal. Other materials such as some bi-metals or oxidised metals can respond with a third (3rd) harmonic signal. The EDD-24XT transmits a focused directional signal on 2.4 GHz (ISM Band Type B). It receives on 4.8GHz (Second Harmonic) and 7.2GHz (Third Harmonic). The highly sensitivity receiver will respond to any signals produced on the 2nd Harmonic by even the smallest piece of Silicon such as that used in SIM Cards, Mobile Phones, Bugging Devices, Voice Recorders, Covert Video cameras etc. Importantly those devices do not have to be in use, in standby or even have any power connected to them to be detected. The 3rd Harmonic receiver acts as a valuable confirmation for signals that may be ambiguous or are not a threat such as those in oxidised metals, bimetals etc. Probability Indicator To allow even an inexperienced user to make a quick assessment of a detected signal the EDD-24XT uses an intelligent algorithm to analyse the detected signals from both the 2nd and 3rd Harmonic Receivers and evaluate the probability of material being detected as ‘Silicon’ or ‘Metal’. Audio Confirmation The EDD-24XT Can provide audio confirmation of detected signals in two ways, through the internal loudspeaker or earphones. Tone Mode can be used to provide an audible tone of a detected signal on the 2nd Harmonic only. This enables the user to search without looking at the display screen. The TONE changes in pitch according to the strength of the detected signal. Demod Mode can be used to listen to an actual demodulated signal of the 2nd Harmonic Receiver. When no signals are detected a random audible ‘Click’ sound will be heard. In some cases when Silicon is detected the click level will reduce or become completely silent. Adjustable head The EDD-24XT features an adjustable head that can be set to one of five positions over a 90-degree angle at the push of a button. 2 x 200g Counterweights are also supplied that can be screwed into the base of the extension pole handle to help balance the assembly for comfort, especially when the pole is extended. Portable The EDD-24XT is genuinely portable weighing less than 900g including the telescopic extension pole. It is encased in a machined aluminium enclosure for ultimate durability with a tough plastic antenna cover. The internal Lithium Polymer battery pack gives up to 4.5 hours of use from one charge. The whole package is supplied in a compact military standard carry case for ultimate protection and portability. Total package weight is just 3.0 kg.
