Driver Settings
The Buffer Size sets the size of DASYLab's buffer. This buffer is made up of a block of the computer's
memory. As a background activity, DASYLab continuously collects data from the acquisition device at
the programmed acquisition rate and places the data into its internal data buffer for processing.
This ensures gapless data under all conditions. Data is stored here until DASYLab can process it.
The status of this buffer is shown (in bar-graph format) in the bottom right corner of the DASYLab
window.
If DASYLab is unable to process the data as fast as it is being collected, the bar graph will begin to fill red.
If DASYLab's buffer completely fills, a buffer overrun error will be encountered.
The Acquisition Mode determines how DASYLab will acquire data.
In Continuous Mode, DASYLab acquires data indefinitely without breaks.
Running Series:
• acquires the number of blocks specified in Blocks Per Series
• pauses for the number of seconds in Delay(Sec)
• repeats the process
The pauses are ignored and the data is seen as continuous.
Isolated Series is the same as Running Series, except the delays are recorded.
One Series acquires the specified number of blocks, then stops.
For DBK2 and DBK5 applications, Series Mode must be used with Pre-Trigger
enabled.
