Difference between Analog Storage and Digital Storage Oscilloscope:

The Difference between Analog Storage and Digital Storage Oscilloscope is given in table below

Analog Storage Oscilloscope (ASO)

Digital Storage Oscilloscope (DSO)
In this Oscilloscope heavy amount of power is to be supplied to the storage CRT. It can store the given indefinitely as long as the small amount of power is supplied to the memory.
It collects the data only after triggering. It always collects the data and stops when triggered.
The cost of the tube is costlier than the storage tube used in DSO. It employs normal CRT, hence the cost of the tube is much cheaper than the storage tube used in ASO.
It cannot produce bright image for high frequency signals. It can produce bright image even for high frequency signals.
In this Oscilloscope, time base is generated by a ramp circuit. In this Oscilloscope, time base is generated by a crystal clock.
It has lower resolution than DSO. It has higher resolution than ASO.
It has high operating speed than DSO. It has less operating speed than ASO.
It doesn’t have aliasing effect. Because of aliasing effect the useful storage bandwidth is limited.
