EM6021 Type Dual Trace 20MHzCRT Digital Readout OscilloscopeDetailed product description：

Performance characteristics of EM6021 dual track 20MHz CRT digital readout oscilloscope

SMT process, imported coded switch, high reliability, high stability.
The microprocessor operating system allows for arbitrary storage and calling of ten different panel settings.
Imported high brightness oscilloscope tube. High precision six bit frequency counter. Its accuracy is as high as ± 0.01%. The cursor can be used to directly read parameters such as voltage, time, frequency, etc.
Misoperation alarm function.
Alternating expansion scanning and dual track four trace display. Y1 channel amplification output function. TV signal synchronization function.
The ALT amplification function allows the main scanning waveform and the amplified scanning waveform to be displayed on the screen simultaneously.
Convenient vertical trigger mode: When the vertical trigger source switches to the vertical trigger mode, the synchronization signal source will be automatically selected.
