YB4328,YB4330 type dual trace oscilloscopeDetailed product description：

YB4328, YB4330 dual track oscilloscope

Functional Features
By expanding the functionality, the sensitivity can be increased to 1mV/div;
The scanning system adopts a full band trigger stone automatic scanning circuit;
The triggering function in terms of flexibility allows for the selection of either a channel signal or an external input signal for departure;
It has the function of alternating triggering and can handle two unrelated signals in the official field;
Equipped with a trigger input terminal, it can output CH1 or CH2 signals along with the trigger channel for external frequency measurement.
