NR-D - EM near-field indicator - frequency meter

Electromagnetic near field indicator - frequency meter "NR-D" is designed for search, detection and localization of places, where various types of concealed active radio transmitting devices are installed.

Channel power meter includes a channel analysis of electric and magnetic components. The results of measuring the phase difference and amplitude ratio is processed and displayed on the display device simultaneously with the classical scale capacity.

"NR-D" has three operating modes:
• Search
• Monitoring
• Log view
Upon detection of a radio transmitter the device informs the operator by audible and visual indication.
Advantages
• High sensitivity
• Near field indication of active transmitter's eliminating false alarms from background signals.
• 4 in 1 design: RF-field detector, frequency meter, digital signals identifier, electromagnetic near-field indicator.
