Product Description
DC-5MHz Student Oscilloscope (Physics instrumnet)
1.overview
The oscilloscope is mainly used for teaching demonstrations and student experiments in colleges and secondary schools. The rate response is DC~5MHz with a vertical deflection coefficient of 20mVp/grid. There is a square wave calibration signal (100mv ± 5%) inside the machine, and the sensitivity scale of the oscilloscope can be adjusted as needed for quantitative testing.
Reasonable arrangement of instrument structure: It has the characteristics of light weight, simple operation, convenient maintenance, low power consumption, and low price. The instrument can be used not only by schools but also by factory maintenance units and scientific research units.
