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.

The AG-107 generator is designed to create alternating current in electrically conductive communications with the electromagnetic method of tracerouting. Features of the AG-107 generator The main distinguishing feature is the small weight and dimensions of the device with high output power. The AG-107 generator has a built-in battery based on light high-capacity lithium-iron phosphate (LiFePO4) cells with low self-discharge, dimensions 216x180x105 mm, weight 1.8 kg and provides the following maximum output parameters: The output power in continuous operation is 30 watts; output power in intermittent operation mode is 60 W; Output voltage 60 V; current 5 A. The AG-107 generator uses a control interface similar to the AG-105 generator. The generator implements: Four sine wave generation frequencies: 512 Hz, 1024 Hz, 8192 Hz and 33 kHz; continuous, pulse and dual-frequency generation modes; built-in transmitting antenna operating at frequencies of 8192 Hz and 33 kHz; the possibility of connecting an external transmitting antenna and induction tongs; built-in "multimeter" displaying, at the operator's choice, the supply voltage or output parameters: current, power, voltage, load resistance; the ability to work from an external battery or from the mains ~ 220 V. The generator can be operated from an external power supply of 10...25 V. The generator is protected from the effects of voltages up to 400 V when connected to the communication and from exceeding the permissible voltage of the external power supply. The degree of protection of the case - case IP65 completely eliminates the penetration of dust and water jets inside when the lid is open.

The AG-120TM generator is designed for localization and diagnostics of underground utilities (cables, pipelines). The maximum power of the generator is up to 300 watts (depending on the selected operating mode). The device has no equal in the qualitative indicator of the ratio: power-resource-dimensions-weight. Application of the AG-120TM generator To trace communications by electromagnetic method (cables, metal pipelines) and acoustic method (metal and non-metallic pipelines). To carry out a highly efficient search for cable damage sites. Carry out diagnostics of gas pipelines and determine the places of damage to the insulation of protective coatings. Work with any receiver due to the possibility of selecting any operating frequency in the range of 200-10000 Hz. Features of the AG-120TM generator Increased battery capacity compared to the AG-120T generator. Automatic matching for a given current in the load, instead of the output power, allows you to get the predicted signal level at the input of the search receiver. The multi-frequency (200-10000 Hz) multifunctional device can be equipped with any search receiver using this frequency range. Automatic selection of output power by an “intelligent” power selection program. The built-in “output multimeter” shows the voltage, current, resistance and power in the load. High output current (up to 15 A) makes it possible to work efficiently on “low-resistance” (up to short-circuit) loads (for example, grounded pipelines). High output voltage (220 V auto./330 V with complement. battery) allows you to effectively trace “high-resistance” long-range communications. Multifunctionality: operation without direct connection with a resonant transmitting antenna, inductive pliers, a shock mechanism and an isolation monitoring sensor. Ability to work in rainy weather (on/off; viewing parameters with the lid closed).

Technical specifications: Frequency range, from 2 Hz to 2 MHz Frequency setting error, ± 1 % Signal amplitude: - at a load of 600 ohms , at least 5 V at least 10 V Smooth signal attenuation, at least 20 dB Frequency instability: - in 15 minutes - for 180 minutes, no more than 0.1% no more than 0.5 % Harmonic coefficient: - in the frequency range from 10 Hz to 20 Hz - in the frequency range sv. 20 Hz to 200 kHz - in the frequency range of 200 kHz to 2 MHz, not more than 0.5% not more than 0.2% not more than 1 %

The automatic tracing generator AG-144.1 is designed to create propagating signals in the routes of hidden communications with active methods of tracing (electromagnetic and acoustic). The device creates in the studied communication an alternating sinusoidal current necessary to determine its location or sound pulses using a shock mechanism. Sinusoidal generation (electromagnetic traceroute method) The selected power levels are issued automatically and are in offline mode: 7.5 W at 0.1...1300 ohms, 15 W at 0.15...660 ohms, 30 W at 0.3...1300 ohms, 60 W at 0.6...660 ohms - CONTINUOUSLY, or 15 W at 0.15...660 ohms, 30 W at 0.3...330 OHMS, 60 Watts at 0.6... 660 ohms, 120 watts at 1.2... 330 ohms - PULSES. When using an additional 12/24 V external battery (for example, a car), an output power of 45 watts at 0.45...2000 ohms, 90 watts at 0.9...1000 ohms CONTINUOUSLY, or 90 watts at 0.9... 1000 ohms, 180 watts at 1.8...500 ohms – PULSES can be achieved. 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 – a highly economical mode with high intelligibility against the background of interference is good for interfacing with analog (mainly single-sensor) receiving systems; continuous – mode is required for most multi-sensor digital receiving systems; three–frequency mode, which provides the selection of the optimal frequency on a remote receiver without switching the frequency of the transmitter (generator). Three generation frequencies: 512 Hz, 1024 Hz, 8192 Hz. Lower frequency means less "readjustment" to neighboring objects and higher broadcast range, higher frequency means higher receiver sensitivity, but greater signal attenuation in "long" communication.

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.
