Figure 3−7: Command processing without using synchronization
The acquisition of the waveform must be completed before the
measurement can be taken on the acquired data. This is achieved by
synchronizing the program so that the measurement command is not
processed by the oscilloscope until the acquisition is complete.
Figure 3-8 shows the desired processing sequence.

Figure 3−8: Processing sequence with synchronization
Four commands can be used to synchronize the operation of the
oscilloscope with your application program: *WAI, BUSY?, *OPC,
and *OPC?. The *OPC? query is the most simple.
Using the *WAI Command
You can force commands to execute sequentially by using the *WAI
command. This command forces completion of the previous
commands before processing new ones.
