IBM Signal Processing - Built-in variables

The following independent variables are built in:

TIME, T, XVEC, X

The range of these variables is taken from the raw data if it contains the variable, otherwise it is set to an array in the range 0.0 - 1.0.

For example:

New X vector ===> TIME
New Y vector ===> -IPLA1

will negate the trace and produce an associated X vector over the complete IPLA1 time vector. In contrast

New X vector ===> TIME
New Y vector ===> SIN(TIME*10.0)

will produce a sine wave over an X axis range of 0.0 - 1.0.
