Figure 15: Peak Detection
Glossary of Terms
•
Collecting mode:
The oscilloscope converts the collected analog data into
digital data for each of the following three modes: Sampling, Peak Detect, and
Averaging.
•
Sampling:
The waveform sampling resolution in seconds. Waveforms that change
faster than the sample duration will not be accurately captured.
•
Peak value detection:
In peak detect mode the meter can capture very narrow
pulses down to 50ns
•
Averaging values:
The oscilloscope averages a selectable number of
measurements. Random noise can be minimized in this mode.
•
Duration time:
A waveform can be held as a new waveform is displayed. The
amount of time the previous waveform is displayed is the ‘duration time’.
•
Roll scan:
The oscilloscope updates the waveform sampling points by scrolling
the screen from left to right (applicable only to primary time base settings above
50ms).
