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 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.

The automatic tracing pulse generator AG-114 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. Features of the AG-114 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 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, 8928 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)" (pulsed 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").

The AG-120T generator is designed for localization and diagnostics of underground utilities (cables, pipelines). The maximum power of the generator is from 120 W to 270 W (depending on the selected operating modes). The device has no equal in the qualitative indicator of the ratio: power-resource-dimensions-weight. Application of the AG-120T generator To trace communications by electromagnetic method (cables, metal pipelines) and acoustic method (metal and NON-metallic pipelines). To perform a highly efficient search for cable damage sites. To carry out diagnostics of gas pipelines and determine the places of damage to the insulation of protective coatings. To work with any receiver thanks to the possibility of selecting any operating frequency in the range of 200-10000 Hz. the features of 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).
