Non Linear Junction Detector EDD-24T Information
Semiconductor Electronics are used in all modern electronics and are made using Silicon substrates. When high frequency radio signals are transmitted directly over silicon, it produces a strong second harmonic frequency of that radio signal. Other materials such as some bi-metals or oxidized metals can respond with a third harmonic signal.
The EDD-24T transmits a focused directional signal on 2.4 GHz (ISM Band Type B). It receives on 4.8 GHz (Second Harmonic) and 7.2 GHz (Third Harmonic).
The highly sensitive 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. Very 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 oxidized metals, bi-metals etc.
To allow an inexperienced user to make a quick assessment of a detected signal, the EDD-24T non linear junction detector uses an intelligent algorithm to analyze the detected signals from both the 2nd and 3rd Harmonic Receivers and evaluate the probability of material being detected as ‘Silicon’ or ‘Metal’.
The EDD-24T NLJD can provide audio confirmation of detected signals in two ways:
- Through the internal loudspeaker; or
- Through 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.
