A set of an autonomous generator MAG-05.2.XX is used for tracing and determining the depth of non-metallic pipelines, storm channels at a depth of up to 5 meters in conjunction with tracerouting receivers having a "Probe" function with an operating frequency of 512 Hz. The principle of tracing non-metallic pipelines with an autonomous MAG-05 generator.2.XX A small-sized autonomous generator MAG-05 is placed on a problematic section of the highway using a cable pushing device. The generator emits an electromagnetic field. When the receiver is moved on the earth's surface (when the receiver axis is perpendicular to the communication axis), a signal with pronounced two local minima, a general maximum and two false peaks is induced along the communication axis in the receiving coil. When moving the receiver across the axis of the generator, there are no local minima and false peaks of the signal.

During operation, the steam generator of metal samples "Aspect" provides control of all devices of the atomic emission spectral analysis complex - the MAES analyzer, the Ball Lightning generator, the inclusion of external devices; A spark unipolar discharge is excited between a tungsten counterelectrode and the surface of the test samples - ingots of precious metals or other metal samples; The intensity of erosion of the sample surface is regulated by changing the repetition frequency and power of spark pulses generated by a computer-controlled semiconductor spark generator; The stability and quality of the frisking is monitored using a built-in spectrometer via optical fiber; An adjustable flow of high-purity argon passes through the spark discharge zone in a sealed discharge chamber, picks up sample particles obtained by spark erosion of the surface and transfers them in the form of an aerosol to the area of the mixer/sprayer of the inductively coupled plasma torch of the optical emission spectrometer.; The flow of high-purity argon is supplied, controlled and regulated by a microprocessor-controlled mass flow controller in the range from 0.5 to 3 l/min. Feed stability 0.01 l/min.

The automatic tracing pulse generator AG-105 is designed to create propagating signals (vibrations) in the routes of hidden communications with the active method of tracerouting. The device creates an alternating sinusoidal current in the studied communication (constantly or in short-term parcels) necessary to determine its location. The features of the AG-105 generator Extremely high power output and battery life, for a compact battery pack ("Type C" × 8) and such small overall dimensions. Universal power supply allows you to reach an output power of over 20 watts. With autonomous power supply, the "life cycle" depends on the quality of the "type C" batteries used. For example, with an initial output power of 7 watts in continuous generation mode, the "life cycle" is ≈ 5 hours, and with an initial output power of 15 watts in intermittent modulation mode, the "life cycle" is ≈ 25 hours (using standard new "fresh" batteries, for example, "Energizer C"). When using "ultra-high-capacity" batteries (for example, "Duracell ULTRA" or "COSMOS"), the battery life can be increased by 20-30%. When connecting an external "12V" battery (for example, a car), the operating time is determined by the capacity of this battery. When connecting an external mains power supply "15 V", the operating time is not limited. The dimensions of the portable device in the case are 216x180x105 mm, and the weight does not exceed 2 kg. These features are provided by the use of an ultra-efficient unique modification of the circuit technology for building CLASS D power amplifiers. The pulse output amplifier reaches an efficiency of 85%, which is especially important for "energy-consuming" devices with autonomous power supply.

The automatic tracer pulse generator "AG-114.1" is designed to create propagating signals (vibrations) in the routes of hidden communications with the active method of tracerouting. The device creates an alternating sinusoidal current in the studied communication (constantly or in short-term parcels) necessary to determine its location. The features of the AG-114.1 generator The selected output power (5 W at 1...1000 ohms, 10 W at 1...500 ohms, 20 W at 1...250 ohms) is issued automatically. The ability to work on such high load resistances allows you to trace very extensive communications. Low power provides energy saving and small "readjustments" to neighboring objects, high power provides a high range of broadcast and detection. Three generation modes: pulse – the main high-efficiency mode with high intelligibility against the background of interference; continuous – an additional low-cost mode for short-term special measurements; three–frequency mode, which provides the selection of the optimal frequency on a remote receiver without switching the transmitter (generator). Three generation frequencies: 512 Hz, 1024 Hz, 8192 Hz. Lower frequency – less "readjustment" to neighboring objects, higher frequency – higher detection range. Unusually compact (190x140x80 mm), for such a high output power (20 W), the autonomous design is provided by the use of highly efficient technology "CLASS D (BD)" (pulse output power amplifier with an efficiency of 80%). As a result, one small-sized autonomous battery with a capacity of only 2.2 Ah provides pulse generation for >5 hours at maximum output power (20 watts). It is possible to work with "recharge" from the charger or increase capacity by connecting an external battery to increase the time resource.

The control and display system, which contains only 4 large keyboard switches and 2 LEDs with specific signatures and symbols ("intuitive interface") and is not overloaded with unnecessary, for automatic devices, fine-tuning organs and indicators of numerical parameter values, is designed for convenient operation in the field. The device does not require constant supervision, parameter monitoring, frequent operational switching and is designed to work on the principle of "turned on and went to the track". In case of significant changes in the load resistance (communication) during generation, the device is automatically reconfigured ("repeated auto-negotiation").
