Compare analog CRO with digital storage oscilloscope (DSO).
|
Analog CRO
|
DSO
|
1 |
High bandwidth
|
Less bandwidth due to aliasing effect
|
2 |
High writing speed about 15 GHz
|
Limited speed
|
3 |
No memory
|
Has memory for storage
|
4 |
high performance converter
|
Low performance
|
5 |
Costlier CRT
|
Cheaper CRT
|
6 |
Low resolution
|
High resolution
|
7 |
the time base is generated by a ramp circuit, so less stability
|
The time base in a digital storage oscilloscope is generated by a crystal clock so that it is more accurate and stable than an analog oscilloscope
|
8 |
Less storage time.
|
The digital oscilloscope is capable of an infinite storage time, using its digital memory.
