Debugging Equipment Used
Frequency scanner- a device that scans a frequency range and intercepts transmissions so that they can be evaluated as being hostile or not. If a hostile transmission is intercepted, then the same device is used to physically locate the transmitter.
The scanner can also be coupled to a down converter antenna so as to cover the widest frequency range possible. Top of the range frequency scanners can also be connected to the mains reticulation system to detect the presence of mains carrier bugs. These bugs transmit information along the mains supply and since they do not transmit any form of radio frequency, they are invisible to standard frequency scanners.
Spectrum analyser- an instrument that resembles an oscilloscope but that has the ability of visually representing high frequency transmissions as waveforms on a screen. This also allows the visualisation of “burst” transmissions that would not ordinarily be picked up on a frequency scanner.
Non linear junction detector (superbroom)- this instrument is used to physically locate the presence of any electronic device by locating the presence of semiconductor components found in all electronic devices. The NLJD emits harmonic waveforms which are disrupted by the presence of these semiconductors (non-linear junctions). The NLJD can therefore also detect such equipment with flat batteries or even switched off. The colloquial term of “superbroom” is attributed to the shape of the device.
