Type specifier

Syntax
signal <identifier>[, <identifier>[, ...]]

Description

Use the signal type specifier to define the acquisition channels. The name of the channel is a special object with signal data type. Declaration of signals has to be after the declaration of all other data types. Variables of signal data types are used as arguments of the detect command. Declared acquisition channels appear in the Experiment Editor. When no signal declaration found in the program, signal channel 'a' is declared automatically.

Example:

signal a,b
detect 'a','-b'

In this example acquisition stream 'b' will be multiplied by -1 prior to storing.
