Portable Noise Generator and Test Tone Generator
The new Portable Noise Generator and Test Tone Generator is a small, compact and power very effective white noise generator optimized to neutralize function of audio listening devices and concealed audio recorders.
Another great feature of this device is a generator of special variable test tone which is optimized for activation of voice controlled listening devices.
The Portable Noise Generator and Test Tone Generator is powered by a built-in battery or accumulator. Microprocessor controlled power amplifier ensures the highest possible power consumption efficiency in the whole output power range. For the standard output power the built-in battery can ensure up to 20 hours of continues operation time. If required external loudspeakers or piezo elements can be connected.
External power supply can be connected for permanent application and/or for charging of the built-in accumulator.
The noise generating circuit is based on the certified noise circuit using a thermal principle of a random noise generation. This design ensures the highest possible resistance against digital filtering methods of reconstruction of the recorded sound.
The TEST TONE is a periodic set of audio frequencies optimized to activate voice controlled listening devices. The TEST TONE mode is a recommended accessory for RF detectors to ensure the most effective RF bug countermeasures.
TEST TONE activates voice controlled listening devices which are then easily detectable by wide band detectors. The detection and bug localization is based on the signal level measurement and on listening to an unmistakable test tone in the RF detector earphone.
