)

This function registers your data buffers, for receiving aggregated data, with the

PicoScope 4000 driver. You need to allocate memory for the buffers before calling this

function.

Applicability

All sampling modes.

For non-aggregated data, use ps4000SetDataBuffer instead.

Arguments

handle, the handle of the required device.

channel, the channel for which you want to set the buffers. Use

one of these constants: -

PS4000_CHANNEL_A

PS4000_CHANNEL_B

PS4000_CHANNEL_C (4-channel scopes only)

PS4000_CHANNEL_D (4-channel scopes only)

bufferMax, a buffer to receive the maximum data values in

aggregation mode, or the non-aggregated values otherwise.

bufferMin, a buffer to receive the minimum data values when

downSampleRatio > 1. Not used when downSampleRatio is 1.

bufferLth, specifies the size of the bufferMax and bufferMin

arrays.

mode, the data reduction mode to use

Returns

PICO_OK

PICO_INVALID_HANDLE

PICO_INVALID_CHANNEL
