' QUERY_WAVE_DATA - Outputs waveform records to the controller
' over the interface that is stored in a buffer previously
' specified with the ":WAVeform:SOURce" command.
' READ_WAVE_DATA - The wave data consists of two parts: the
' header, and the actual waveform data followed by a
' New Line (NL) character. The query data has the following
' format:
'
' <header><waveform data block><NL>
'
' Where:
'
' <header> = #800002048 (this is an example header)
'
' The "#8" may be stripped off of the header and the remaining
' numbers are the size, in bytes, of the waveform data block.
' The size can vary depending on the number of points acquired
' for the waveform which can be set using the
' ":WAVEFORM:POINTS" command. You may then read that number
' of bytes from the oscilloscope; then, read the following NL
' character to terminate the query.
' Read waveform data.
nLength = oscp.DoQueryIEEEBlock(":WAVeform:DATA?", ResultsArray)
Console.WriteLine("Read waveform data ({0} bytes).", nLength)
' Make some calculations from the preamble data.
