GENERAL DESCRIPTION
(Adjustable 40 – 53 dBm)
The counter surveillance equipment PHJD900 has been designed for detection of nonlinear junctions.
Nonlinear junctions include a wide variety of components such as diodes, transistors, IC’s, etc.
The PHJD900 is especially used for IED detection.
The PHJD900 can detect electronic circuits such as hidden transmitters, tape recorders and Cellular phones even when DC source is NOT applied.
The PHJD900 is a state-of-art Non Linear Junction Detector based on the latest technology and includes DDS and DSP components.
The system equipped with high selectivity receiver along with unique detection algorithm achieving high sensitivity of -133 dBm.
The system provides an evaluation of the 2nd and 3rd harmonic.
When the system receives a strong 2nd harmonic, it indicates the presence of electronic components while a strong 3rd harmonic reception indicates false corrosive junctions, hence discards false alarms.
Both 2nd & 3rd harmonics are displayed at the same time.
