Synchronization with an Averaging Acquisition

When remotely controlling an oscilloscope with programming commands, it

is often necessary to know when the oscilloscope has finished the previous

operation and is ready for the next command. The most common example

is when an acquisition is started using the :DIGitize, :RUN, or :SINGle

commands. Before a measurement result can be queried, the acquisition

must complete. Too often fixed delays are used to accomplish this wait,

but fixed delays often use excessive time or the time may not be long

enough. A better solution is to use synchronous commands and status to

know when the oscilloscope is ready for the next request.
