'Capture - After initialization, you must make waveform data
'available to analyze. To do this, capture the data using the
'DIGITIZE command.
Capture
'Analyze - Once the waveform has been captured, it can be analyzed.
'There are many parts of a waveform to analyze. This example shows
'some of the possible ways to analyze various parts of a waveform. Analyze

'Initialize
'
'Initialize will start the program with the oscilloscope in a known
'state. This is required because some uninitialized conditions could
'cause the program to fail or not perform as expected.
'
'In this example, we initialize the following:
'- Oscilloscope
'- Channel 1 range
'- Display Grid
'- Timebase reference, range, and delay
'- Trigger mode and type
'
'There are also some additional initialization commands, which are
'not used, but shown for reference.

Private Sub Initialize()
'Clear the interface. err = viClear(vi)
'RESET - This command puts the oscilloscope into a known state.
'This statement is very important for programs to work as expected.
'Most of the following initialization commands are initialized by
