The DAS is designed around the feature of a "record". A record is a single data
point of one parameter, stored in one (or more) data channels and generated by
one of several triggering event. The entire DAS configuration is stored in 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.
DAS data are defined by the PARAMETER type and are stored through different
triggering EVENTS in data CHANNELS, which relate triggering events to data
parameters and define certain operational functions related to the recording and
reporting of the data.
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; each channel can contain one
or more parameters. For each channel one triggering event is selected and up to
50 data parameters, which can be the same or different between channels. Each
data channel has several properties that define the structure of the channel and
allow the user to make operational decisions regarding the channel (Table 4-7).
