Synchronizing Acquisitions
Synchronization in the Programming Flow
Most remote programming follows these three general steps:
1
Set up the oscilloscope and device under test (see
2
).
3
Retrieve results (see
Set Up the Oscilloscope
Before making changes to the oscilloscope setup, it is best to make sure it is
stopped using the :STOP command followed by the *OPC? query.
Acquire a Waveform
When acquiring a waveform there are two possible methods used to wait for the
acquisition to complete. These methods are blocking and polling. The table below
details when each method should be chosen and why.
Retrieve Results
Once the acquisition is complete, it is safe to retrieve measurements and statistics.
NOTE
It is not necessary to use *OPC?, hard coded waits, or status checking when setting up the
oscilloscope. After the oscilloscope is configured, it is ready for an acquisition.
Blocking Wait
Polling Wait
Use When
You know the oscilloscope
will
trigger
based on the oscilloscope setup and
device under test.
You know the oscilloscope
may or may
not
trigger on the oscilloscope setup
and device under test.
Advantages
No need for polling.
Fastest method.
Remote interface will not timeout
No need for device clear if no trigger.
Disadvantages
Remote interface may timeout.
Device clear only way to get control of
oscilloscope if there is no trigger.
Slower method.
Requires polling loop.
Requires known maximum wait time.
