Following are main difference between dual trace CRO and dual beam CRO
|Dual trace CRO
||Dual beam CRO
|It is used single electron beam to display two traces.
||It is used two electron beams for displaying two signals.
|A single vertical amplifier is used.
||Two vertical amplifiers are used for two beams.
|It is not able to capture two fast transient events.
||It is captures two fast transient easily.
|It cannot switch quickly between traces, so simultaneous display becomes difficult.
||It can display two traces simultaneously.
|The two signals may or may not have same frequency.
||The two signals must have the same frequency or they must be harmonically related.
|A single beam can be used for displaying multiple traces.
||Multiple beams are used for displaying multiple traces.
|Two signals can be displayed on a dual trace oscilloscope. But, the two signals cannot be displayed together in real time.
||Two signals can be displayed simultaneously in real time.
