7 Remote Acquisition Synchronization
Acquiring 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.
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 based on the
oscilloscope setup and device under
test.
Advantages
• No need for polling
• Fast 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
• Required polling loop
• Required known maximum wait
time
