Dual Beam Dual Trace CRO
|
1 |
A single electron beam is used to display two traces.
|
Two electron beams are used for displaying two traces/signals.
|
2 |
A single vertical amplifier is used.
|
Two vertical amplifiers are used for two beams.
|
3 |
The two signals may or may not have same frequency.
|
Two signals must have the same frequency or they must be harmonically related.
|
4 |
Single Beam oscilloscope is not able to capture two fast transient events.
|
Dual Beam oscilloscope captures two fast transient events easily.
|
5 |
Simultaneous display of two traces is very difficult in Single Beam oscilloscope.
|
Simultaneous display of two traces is very simple in Dual Beam oscilloscope.
