This function is used after the driver has finished collecting data in fast streaming mode. It

allows you to retrieve data with different aggregation ratios, and thus zoom in to and out of

any region of the data.

Before calling this function, first capture some data in fast streaming mode, stop fast

streaming by calling ps2000_stop, then allocate sufficient buffer space to receive the

requested data. The function will store the data in your buffer with values in the range

PS2000_MIN_VALUE to PS2000_MAX_VALUE. The special value PS2000_LOST_DATA is

stored in the buffer when data could not be collected because of a buffer overrun. (See

Voltage ranges for more on data values.)

Each sample of aggregated data is created by processing a block of raw samples. The

aggregated sample is stored as a pair of values: the minimum and the maximum values of the

block.
