5.1 SPECIAL TYPES OF OSCILLOSCOPES
In some applications, the input signal given to the circuit or system and the output signal are to be observed simultaneously and analysed. Hence, the cathode ray oscilloscope (CRO) must have provision to give two signals to two different Y-plates and separate time bases. Such CROs are called double beam oscilloscopes. ...
