A variety of different display options are available
within DASYLab, including the ability to produce Fast Fourier
Transformation (FFT)
trigger-based data acquisition, generating alarms, and other simple automation-
based tasks. The Full package is suited to a wide range of applications including
those that might have to run unattended or require fully automatic operation.
The most sophisticated and most powerful version of the software, DASYLab
Pro, contains the same features as the Full versions with the addition of more
signal analysis, a Sequence Generator, high-end or complex frequency analysis,
additional filtering, and other tools. DASYLab Pro is ideal for creating stand-
alone test and measurement applications with a powerful set of data analysis
tools.
Finally DASYLab Net is an extension of DASYLab that uses TCP/IP to
communicate with (and control) remote copies of DASYLab Net. This version
of DASYLab can be used to remotely start, stop, and load measurement data,
including simultaneous starts of several DASYLab Net systems.
DASYLab's programming interface is extremely straightforward and is based
on a graphical programming environment. Sophisticated data acquisition and
control tasks can be solved without any language-based programming and it
is only necessary to insert the appropriate module symbols into the worksheet
and connect them by wires. The module symbols represent inputs or outputs,
display instruments, or any of the range of operations provided by the program,
while the data channels represent the signal flow (Figures 10.12-10.15).
DASYLab provides support for more than 250 data acquisition boards
through appropriate drivers. Data acquisition hardware can also be connected to
DASYLab through the RS-232 and/or IEEE-488 bus modules. In addition, data
can be exchanged between DASYLab and other Windows applications using
Dynamic Data Exchange (DDE) techniques.
