Display data—for extended-period trend recording
The display data format is used to save data displayed as waveforms.
Each time the waveform display is updated, two data values (maximum and minimum values) measured since the previous update are saved.
File structure
The two data formats can be used in combinations such as the following:
1. Display data only
2. Event data only
3. Display data and event data in combination
Display data, event data, and a trigger function can be used in combination.
With this approach, display data with a slow sample rate can be
used for continuous extended-period recording, and event data with a
faster sample rate can be used to record short-term details.
