Synchronizing Acquisitions

 

Synchronization with an Averaging Acquisition

When averaging, it is necessary to know when the average count has been 
reached. The :SINGle command does not average.

If it is known that a trigger will occur, a :DIGitize will acquire the 
complete number of averages, but if the number of averages is large, a 
timeout on the connection can occur.

The example below polls during the :DIGitize to prevent a timeout on the 
connection.
