APPLICATION
NR-2000 Non-linear Junction Detector is intended for searching
concealed electronics like eavesdropping installations, Remote
Controlled Improvised Explosive Devices (RC IED) and etc. as well
as other items that contain semi-conductor elements.
NOTE: NR-2000 can detect typical targets in every
operational mode: active, stand-by or even switched-off.
NR-2000 typical targets:
-Radio-mikes
-Microphone amplifiers
-Wired mikes
-Video & audio recorders
-SIM cards
-Electronic timing devices
-Devices with infrared (IR) or ultrasonic data & control channel
-Remote Controlled Improvised Explosive Devices (RC IED)

NR-2000 possible application fields
-Crime scene investigation for hard evidence of explosive
terrorism that contains any electronic components and its remains:
triggers, communication facilities and etc.).
-Searching for Improvised Explosive Device (IED) that contains
electronic components in typical urban environment.
NOTE 1: In practice NR-2000 is immune to interfering signals typical
to urban conditions.
NOTE 2: The IED detection range is comparable with that of an ‘Eagle’
NLJD –Russian standard tool for field operations: 7-10 meters.
NOTE 3: Fortunate combination of significant detection range with low
radiation level and practical immunity to unban interference
guarantees NR-2000 operator from spontaneous IED triggering.
-Various premises investigation for mobile phones and SIM-cards
hidden in domestic articles.
NOTE: NR-2000 ensures mobile phones and SIM-cards detection in
moist environment and light construction materials up to the distance
of 1m and 0.5m respectively.
-Searching for eavesdropping devices concealed in light building
structures, furniture and various home appliances as well as their
reliable localization.
NOTE 1: NR-2000 can easily detect targets in building structures
behind their reinforcement elements (steel grid and etc.)
NOTE2: NR-2000 provides its operator with an opportunity to
discriminate between industrial electronic elements and metal-to-metal
contacts, so called ‘corrosion diodes’.
NR-2000 NLJD represents a
comprehensive multi-purpose tool
with mid-power output and an outstanding
searching ability and rate.

PRINCIPLE OF OPERATION
NR-2000 detector represents a portable device that consists of antenna
system, probing signal transmitter and 2 receivers tuned to the double
& triple frequencies of the emitted signal.
Mono-harmonic probing signal emitted by transmitter is converted by
non-linear elements (industrial semi-conductor or corrosion
metaloxide-metal structure) to poly-harmonic one and re-radiated into
an ambient space.
The re-radiated 2-nd & 3-rd harmonic of the probing signal are received
and processed by above-mentioned receivers (see fig. 3).
The received signals levels are displayed by two bar-graph scales: ‘2’
(red) & ‘3’ (green) respectively.
Furthermore, at the same time tonal acoustic signal is reproduced bythe
headphones. The tonal signal level corresponds to that of the received
electric signals.
Volume control is adjusted by (+ VOL -) buttons of the Control unit.
At that a corresponding bar-graph scale is switched over for sound level
indication for one sec.

The received signal level can be adjusted by Control unit with
appropriate LED confirmation.
20K-mode activated by Control unit is used for revealed target
identification. This auxiliary mode allows operator to evaluate probable
probing signal amplitude modulation.
DESIGN
NR-2000 Main unit consist of antenna module, probing signal
transmitter unit, two receivers, telescopic bar and control unit with LED
display (fig. 4). The unique ‘Bullpup’ design provides NR-2000
ergonomic advantages in any possible application.
