)

This function returns data either with or without downsampling, starting at the

specified sample number. It is used to get the stored data from the scope after data

collection has stopped. It returns the data using a callback.

Applicability

Streaming mode and block mode

segmentIndex: see ps6000GetValues

lpDataReady, a pointer to the user-supplied function that will be

called when the data is ready. This will be a ps6000DataReady

function. The data type is determined by the application.
