• You can do additional processing on the result by applying either standard instrument parameters, functions,
etc. to the returned result, or even more powerfully, adding chained customized functions. For example, you

Examples
WaveOut is the waveform being returned to the instrument (F1 in this case). WaveIn is the input waveform (C1 in
this case) You can see that the F1 result is displayed on the oscilloscope, and can be processed further.
VBS C E XAMPLE 2: A NOTHER SIMPLE MATH FUNCTION USING RIPT
Example 3 below doesn’t use the input data at all. The middle waveform (F2) is a "golden waveform", in this case
a perfect sine (subject to 16-bit resolution), that was created using a VBScript. The lower trace (F3) is a
subtraction of the acquired waveform (upper trace) and the golden waveform. The subtraction (of course)
contains all the noise, but it also shows the presence of a very small square wave signal.
