To understand instrument drivers, you should start by reading chapter 16 of the LabVIEW Measurments Manual. This is a shipping document that you can access from Help>Search the LabVIEW Bookshelf. Your specific driver comes with a VI called hp548xxa Getting Started. This is a high level example that demonstrates how the subVIs in the driver can be used. You should look at this first and get this working. The actual subVI that gets waveform data is hp548xxa Data Read Waveform. This returns a single channel's data as a 1D array and x scale information (timing) as scalars. You can wire this data to Write to Spreadsheet File or create a waveform data type for each channel acquired and use Export Waveforms to Spreadsheet File. The attached example demonstr
ates this method. Hope it helps.
