Description

(1) Technical field

[0001] The invention relates to a multi-channel isolation function signal generator, in particular to a multi-channel function signal generator that requires channel isolation, synchronization, multi-signal superposition, and large signal voltage variation range. (2) Background technology

[0002] The function signal generator is a kind of signal generator, because it can generate sine waves with different amplitudes, different frequencies, and different phases, it is usually used as an excitation source in scientific research and equipment testing in many fields. For excitation signal sources in non-communication fields, the signal frequency band does not need to be very high. In some occasions, it is necessary to provide several channels of electrically isolated waveform signals as the excitation of different electrical equipment components, and sometimes these electrically isolated multi-channel signals are required to maintain a certain phase relation...
