' Here's a small example that just inverts the waveform.
OutResult.Samples = InResult.Samples
startData = 0
endData = OutResult.Samples
newNumPoints = endData - startData
ReDim newDataArray (OutResult.Samples)
unscaledData = InResult.DataArray (False)
For i = 0 To endData - 1
newDataArray (i) = - unscaledData (i)
Next
OutResult.DataArray (False) = newDataArray _ ' only support raw data
The four highlighted quantities are parts of the interface. The names must be retained.
Furthermore, InResult.Samples and InResult.DataArray are inputs, and their values cannot be
changed. OutResult.Samples and OutResult.DataArray are outputs, and can be changed, but not
directly through their individual elements.
The default parameter function script: explanatory notes
The default parameter script is similar to the default waveform script, but there are subtle
differences.
First, the size of the data array is the same as the nominal value: you cannot use or see the extra
two points. So "500 points" means just that: 500 points.
Second, the output looks like an array, but only element zero is currently used. You must copy
your parameter result into newValueArray(0). As with the arrays of the Waveform Script, you
cannot refer directly to elements of the input and output arrays. You may not write something like
OutResult.ValueArray (0) = P.
Note that the unit of the parameter is displayed as the same as the vertical unit of the trace, even
if you have squared the data, for example, unless you change the unit yourself.
