The DAS is designed around the feature of a "record", an automatically stored single
data point. (e.g. concentration, PMT signal level, etc.). Records are organized into data
channels which are defined by properties that characterize the:
•
Type of date recorded (e.g. concentration, PMT signal level, etc.);
•
Trigger event that causes the record to be made (e.g. every minute, upon exiting
calibration mode, etc.);
•
How many records to be stored, as well as;
•
How the information is to be stored (e.g. average over 1 hour, individual points,
minimum value over last 5 minutes, etc.).
The configuration of each DAS channel is stored in the analyzer's memory as a script,
which can be edited from the front panel or downloaded, edited and uploaded to the
instrument in form of a string of plain-text lines through the communication ports.
The key to the flexibility of the DAS is its ability to store a large number of
combinations of triggering events and data parameters in the form of data channels.
Users may create up to 20 data channels. For each channel one triggering event is
selected and one or all of the T200H/M's 25 data parameters are allowed. The number
of parameters and channels is limited by available memory.
The properties that define the structure of an DAS data channel are:
