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
can do an Excel calculatio

Solutions

Engineers do not buy equipment; they buy solutions. But what solutions can be

Changing the units of a grid to joules, newtons, amps, etc.
Creatin

Creating a new waveform without using any of the input data

You don't have to use all the data from the input waveforms: you can select data from one or more segments,

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.

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.
