Q
What’s the shortest event duration that can be detected by the event recording function?
A
Specifications vary by instrument.
Which measurement functions can be used by the event recording function depends on the instrument.
In addition, threshold value settings, the maximum number of events that can be saved, and the minimum detectable event duration vary from instrument to instrument.
Please exercise care concerning each instrument’s specifications.
- When the maximum number of events that can be saved is recorded, measurement will stop, and subsequent events will not be recorded.
- It may not be possible to detect events that last less than the minimum detectable event duration due to the inability to measure them accurately.
