Appendix A The Module Groups
A-2 | dasylab.com
The sub-folder RS232 contains the modules RS232 Input and RS232
Output to exchange data and text with external measurement devices that are
connected to the serial interface.
The sub-folder IEEE 488 contains the modules IEEE488 Input and
IEEE488 Output to exchange data with external measurement devices
connected to IEEE boards.
The sub-folder IVI contains the modules IVI Counter, IVI DCPower,
IVI Digital Multimeter, IVI Switch, and IVI Scope which are based on the
respective class specifications of the IVI foundation.
The Trigger Functions Modules Group
The trigger functions modules group contains various trigger modules to
control the data flow in the worksheet with conditions. When the condition
is met, trigger modules output a TTL signal.
The Pre-/Post-Trigger module continuously monitors whether data
channels exceed limit values whereas the Start/Stop Trigger module checks
when data channels exceed a limit value the first time. The Combi Trigger
module continuously monitors the start condition and then the stop condition
of data channels.
The Sample Trigger module continuously monitors the duration of trigger
events, whereas the Trigger on Demand module monitors the increase or
decrease of successive measurement values.
The Relay module outputs the connected data channels when a trigger input
or an action meets the condition. Unlike the other trigger modules, the
module does not output TTL signals.
The Mathematics Modules Group
The mathematics modules group contains modules to process data channels
mathematically.
Use the Formula Interpreter to define your own formulas, to calculate data
channels, and to combine several data channels with each other. In the
Arithmetic module, you select predefined functions to calculate one data
channel or to link two channels. The Trigonometry module uses
