J2458-1 teaching oscilloscope
Main function introduction:
The vertical system frequency response is DC ~ 5MHz, and the vertical deflection factor is not more than 20MVp.p / grid.
There is a 100MV±5% square wave calibration signal in the machine, which can be used for vertical system sensitivity as needed.
Calibration, to achieve quantitative test of the amplitude of the measured waveform, the test error is not more than 10%.
