Cathode Ray Oscilloscope

The CRO is used to measure the voltage, current, frequency, inductance, admittance, resistance, and power factor.
This device is also used to check the AM and FM circuits characteristics
This device is used to monitor the signal properties as well as characteristics and also controls the analog signals.
The CRO is used through the resonance circuit to view the shape of the signal, bandwidth, etc.
The shape of voltage and current waveform can be observed by CRO which helps to take the necessary decision in a radio station or communication station.
Used for comparing phase & frequency
It is used in TV, Radar, and analysis of engine pressure
To check the reactions of nervous and heartbeat.
In the hysteresis loop, it is used to find BH curves
Transistor curves can be traced.
