NLJD RB S- Non-linear junction detector
The only multifunctional non-linear junction detector featuring an integrated spectrum analyzer of 2nd and 3rd harmonics and changeable transmitter-receiver antennas of 3 frequency bands: 800 MHz, 2400 MHz and 3600 MHz. Integrated spectrum analyzer can significantly improve the identification of semiconductor elements (only for antenna 2400 MHz).
Advantages
- Integrated spectrum analyzer of 2nd and 3rd harmonics can significantly improve the identification of semiconductor elements (only for 2400 MHz)
- The operator can analyze not only the amplitude, but also the spectrum of 2nd and 3rd harmonics signals re-emitted by a non-linear object, relative to probing frequency, which increases informational content of the non-linear features of the object. In particular, that considerably facilitates decision-making on the separation of corrosive and artificial semiconductors.
- There is a built-in module measuring the reflected power of the probing signal from the research object, which allows it to estimate the extent of the reflecting surface of the object.
- Use of 3 replaceable transmit/receive units significantly reduces the probability of missing a thing at search operations providing major advantages in all three ranges:
-800 MHz – all-weather and relatively low attenuation of signals in dense medium (brick, concrete, etc.),
-2400 MHz – the opportunity to detect SIM cards and small (about 1 cm?) semiconductor devices,
-3600 MHz – providing spatial selection, which facilitates search operations in premises containing legal electronic devices. - Time to replace transmit/receive units and extension rod will not exceed a few minutes.
- Reliable detection of the SIM-card at a distance of 15 cm (2400 MHz) and 60 cm (3600 MHz).
- For efficient identification of artificial and natural semiconductors a visual spectrum analyzer is used or listening through a built in speakerphone or headphones after AM decoding of the signal in continuous mode is done.
- NLJD RB S is equipped with an automatic system of protection against centered jamming by criterion of a minimum noise in the receiver path of the 2nd harmonic.
- Electromagnetic radiation towards the operator is many times less than one setted by the Regulator.
