Multifunctional search device "ST131.S PIRANHA II"

The multifunctional search device "ST131.S PIRANHA II" is designed to carry out activities to detect and determine the location of special technical means (STS) for covert information acquisition and to identify natural and artificially created information leakage channels.

Differences from the previous model "ST131.N PIRANHA II":

The frequency range of the first channel "RADIO" is expanded to 6 GHz
The UHF Converter is structurally located in the main unit
The module for providing bias voltage is located in the wire line adapter.
Power supply from four Li pol batteries of the 16650 type.
Keyboard backlight
The main types of STS, the detection of which is focused on ST131.S, are: STS with information transmission:

via a radio channel.
in the sound and ultrasonic frequency range.
in the infrared frequency range.
via wire lines, including: AC power networks, telephone, coaxial and lines of fire and security alarm systems.
The design of ST131.S provides for two main operating modes:
Portable, using the capabilities of the main unit and additional devices
Stationary using the original software "ST131Analyzer.pro".

WIRE LINE ADAPTER ST131.S.AWL

ST131.S.AWL is designed to connect the main unit to wire lines of various purposes
ST131.S.AWL is a monoblock that structurally combines:
A step-down transformer voltage converter designed to operate in the frequency range of 0.01-30 MHz.
A differential low-frequency amplifier designed to operate in the acoustic frequency range (0.3-15 kHz).
A switching unit controlled directly from the main unit and providing connection of the required pairs of RJ-45 connector contacts. Connection is made for both the most common combinations of pairs and arbitrarily, in a user-defined option
Nonlinear transition detector generator
Bias voltage supply circuit designed to supply bias voltage (power) to a wire line in order to activate special technical means of covert information acquisition connected to this line

RADIOFREQUENCY WIRE LINE ADAPTER ST131.S. RAWL
ST131.S.RAWL is designed to connect the main unit to coaxial lines.

ST131.S.RAWL is a monoblock with built-in protection elements that prevent the input circuits of the main unit from failing.

UHF ANTENNA ST131.S.UHF.A
ST131.UHF.A is a passive broadband antenna

CONTROL DEVICE "ST131.TEST
ST131.S.TEST is designed to control the performance of the ST131.S PIRANHA II. All detection channels are checked, both the main unit itself and the sensors included in the kit.

ST131.S.TEST has six sources of control signals corresponding to the ST131.S detection channels and a nonlinear element designed to check the nonlinear transition detector.

MAGNETIC FIELD SENSOR "ST131.MF"
The sensor structurally consists of a ferrite antenna and an amplification unit.
"ST131.S.MF" operates in two modes:

"MAGNETOMETER". In this mode, magnetic field strength measurements are made.
"GRADIENTOMETER". In this mode, the difference in field strength is measured at two points on the magnetic axis located symmetrically relative to the center, which ensures significant attenuation of remote powerful sources magnetic field, as well as other interfering effects (acoustic, vibroacoustic, etc.).
MICROWAVE ANTENNA - DETECTOR "ST131.SHF
ST131.S.SHF is designed to detect signals in the microwave range of 6-18 GHz
ST131.S.SHF consists of a log-periodic antenna and a microwave detector structurally combined in one housing.
INFRARED SENSOR "ST131.S.IR
T.131.S.IR is designed to detect signals in the infrared frequency range.
This sensor structurally combines an optical system, a receiving photodiode and a preamplifier. The telescopic tripod is designed to facilitate the search for IR transmitting devices installed, for example, on the outside of a window opening in the direction "from the window".
The rotary mechanism ensures the prompt installation of the required viewing angle in the range of up to 180 °.

ACOUSTIC SENSOR "ST131.S.A"
It is designed to receive acoustic signals in the sound and ultrasonic frequency range.

This sensor structurally combines a microphone and an amplifier

DETECTION CHANNELS
