Signal Generator

      Signal generator is a multifunctional and high-precision portable signal source, which can provide frequency, waveform and output electrical signal. Especially used in optogenetics, by changing the parameters such as laser amplitude, time, precise light control can be achieved for specific cells of the organism to control the behavior of the cells. The pulse train signal can be designed and manufactured according to customer requirements to realize high and low level conversion or cyclic conversion.

Testing Instrument: Signal Generator
