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-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.
