PicoScope4000GetRapidBlock.vi - collects a set of data blocks or captures

from the oscilloscope in rapid block mode

This VI is similar to PicoScope4000GetBlock.vi. It outputs two-dimensional

arrays for each channel that contain data from all the requested number of

captures.

PicoScope4000GetStreamingValues.vi - used in streaming mode to get the

latest values from the driver

This VI should be called in a loop after the oscilloscope has been set up using

PicoScope4000Settings.vi and streaming has been started by calling

PicoScope4000StartStreaming.vi. The VI outputs the number of samples

available and the start index of these samples in the array output by

PicoScope4000StartStreaming.vi.

PicoScope4000Open.vi - opens a PicoScope 4000 and returns a handle to the

device

PicoScope4000Settings.vi - sets up the oscilloscope

The inputs are clusters for setting up channels and simple triggers. Advanced

triggers can be set up using PicoScope4000AdvancedTriggerSettings.vi.

PicoScope4000StartStreaming.vi - starts the oscilloscope streaming

It outputs arrays that will contain samples once

PicoScope4000GetStreamingValues.vi has returned.

PicoStatus.vi - checks the status value returned by calls to the driver

If the driver returns an error, the status member of the error cluster is set to ‘true’

and the error code and source are set.
