Signal simulators are used in training in searching for special technical means of covert information acquisition, testing the functionality of search equipment (in this case, the simulator can be called: a signal simulator tester). At the same time, they are often used in conducting various laboratory measurements not directly related to the topic of information security. The closest analogy in military topics is radar signal simulators.
The main prerequisites for using signal simulators are the following:
The acquisition and use of listening devices, without a special permit, is prohibited by law. The simulator precisely simulates radiation without intercepting information. It can be used without special permits. There are many classes, types and subtypes of listening devices. For example, in order to formally replace a fully functional signal simulator, several test signal generators with appropriate antennas, adapters, converters and emitters will be required. At the same time, let's not forget about the weight and size characteristics. Of course, these devices are superior to signal simulators in terms of metrological parameters - stability, repeatability, etc., but in the context of the main purpose - training - this is not essential. There are many options for signal simulators. From a mini radio transmitter the size of an alarm key fob, to a multi-channel complex with a large library of signals and PC control.
A multifunctional signal simulator generates radiation in a very wide frequency range: from infrasound to the optical range. At the same time, the signal simulator has the ability to connect to various wire lines, up to 220V. It has an autonomous power supply, has small dimensions and a shockproof case.
