Abstract

The invention provides a multifunctional signal generator. The multifunctional signal generator includes a signal generation module for generating digital signals, an input module, a display module, amain control module, an output interface and a plurality of communication branches, wherein each communication branch includes successively connected digital-analog converter, power amplifier, filtering voltage-stabilizer and attenuator; the signal generation module is connected with the digital-analog converters of the plurality of communication branches; and the input module, the display module, the attenuators and the output interface are connected with the main control module. In the multifunctional signal generator, the digital signals generated from the multifunctional signal generatorcan output analog signals with different level intensities after passing the plurality of communication branches; the analog signals are output through the output interface, and are displayed on the display module at the same time, so that the plurality of analog signals with different level intensities are input in the certain range so as to satisfy the requirement for some specific occasions.

Description

technical field [0001] The invention relates to the field of computers, in particular to a multifunctional signal generator. Background technique [0002] A signal generator, which is used to generate electrical test signals of specific parameters required by the circuit under test. When testing, researching or adjusting electronic circuits and equipment, in order to measure some electrical parameters of the circuit, such as measuring frequency response, noise figure, and voltmeter calibration, etc., it is required to provide electrical signals that meet the specified technical conditions to simulate in practice. The excitation signal of the equipment under test used in the work, so the signal generator is one of the very important instruments in the factory and electrical automation professional laboratory. However, the level intensity of the output signal of the existing signal generator is constant, which cannot meet the requirements of some specific occasions. Content...
