get aquisition without a trigger

[wdehoog]

Hi,

Using a trigger (acquisition mode SINGLE) I can get a full acquisition. Now I would like to have one without a trigger.

Waiting for FullAcquisitionFetchProgress >= 1 does not seem to work. It waits forever.

Combining multiple Viewport sets (p.GetData(ChannelDataSourceScope.Viewport,...)) results in weird data, as if the Viewport data are only triggered small chunks.

What is the best way to get an X number of samples starting from 'now'?

You can indeed set it to single to get a full acquisition without a trigger caused by the signal, but in order for the scope to quit scanning for a trigger, you need to send a trigger from your code manually usign IScope.ForceTrigger() <https://github.com/labnation/DeviceInterface/blob/master/src/Devices/IScope.cs#L142> Once the scope stops scanning, it retains the acquired data in memory and will start sending it to the host chunk by chunk Jasper
