PicoScope4000aGetStreamingValues.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

PicoScope4000aSettings.vi and streaming has been started by calling

PicoScope4000aStartStreaming.vi. The VI outputs the number of samples

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

PicoScope4000aStartStreaming.vi.

PicoScope4000aOpen.vi - opens a PicoScope 4000 and returns a handle to the

device

PicoScope4000aSettings.vi - sets up the oscilloscope

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

triggers can be set up using PicoScope4000aAdvancedTriggerSettings.vi.

PicoScope4000aStartStreaming.vi - starts the oscilloscope streaming

It outputs arrays that will contain samples once

PicoScope4000aGetStreamingValues.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.
