Figure 3- 7: Command processing without using synchronization
To ensure the oscilloscope completes waveform acquisition before taking the
measurement on the acquired data, you can synchronize the program. Figure 3 --8
shows the desired processing sequence.

Figure 3- 8: Processing sequence with synchronization
You can use four commands to synchronize the operation of the oscilloscope
with your application program: *WAI, BUSY?, *OPC, and *OPC?.
You can force commands to execute sequentially by using the *WAI command.
This command forces completion of the previous commands before processing
new ones.
The same command sequence using the *WAI command for synchronization
looks like this:
REM “Set up single-sequence acquisition”
SELECT:CH1 ON
HORIZONTAL:RECORDLENGTH 500
ACQUIRE:MODE NORMALSAMPLE
ACQUIRE:STOPAFTER SEQUENCE
REM “Acquire waveform data”
ACQUIRE:STATE ON
REM “Set up the measurement parameters”
MEASUREMENT:IMMED:TYPE AMPLITUDE
MEASUREMENT:IMMED:SOURCE CH1
REM “Wait until the acquisition is complete before taking the measurement”
