InResult.DataArray(False) means that the data are signed integers in the range -32768 to 32767. False is a
Boolean value applying to the property Scaled. Scaled data are specified in the units of the vertical scale, such as
volts. You get these by putting "True" instead of "False". If you want to make a section of the output trace
invisible, you simply set the data values to full scale or bigger, top or bottom.
You can start with the unscaled data (False) as input, and then set the output data to scaled data (True), and you
can go from scaled to unscaled. Using scaled data, an overflow will make a picture like this:
You can also start with True and convert to False, but in this case overflows will cause an error message.
Anything after a single quotation mark on a line will not be used by the instrument. This feature is intended for
comments, for example
' This is a comment.
A = Amp * Sin(Omega * T) Calculate the output.
InResult.DataArray and OutResult.DataArray are only to be used as shown in the default scripts and in the
example scripts: you cannot refer directly to individual elements of these arrays. You have to use your own
arrays, in this example, unscaledData and newDataArray. You are not allowed to write statements like the
following:
Y = InResult.DataArray (17)
OutResult.DataArray (257) = Z
Some parts of the default script must not be changed because they are a part of the interface. These are
highlighted in the following script .
' TODO add your custom code here accessing OutResult and InResult objects
' 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.
