GENERAL SPECIFICATION :

This is a portable kind of oscilloscope for two traces. The bandwidth of 30MHz is 0~30MHz. its vertical deflection factor is 5mV/div and to 1mV/div by Magnification. Full bandwidth sweeping circuit is used in the sweeping system. The flexible and convenient triggering mode has the functions for selecting signals from one channel or triggered by Ext signals. And there is another function of ALT trigger to observe signals from two irrelative channels.  

The instrument is of easy operation with comfortable controls. Its reasonable structure and technology makes it conveniently to repair and calibrate. 

COMPONENT TEST :

Component tester is the special circuit with which a single component or components in or out of actual circuit board can be easily tested requiring no power to drive the circuit
