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 TDS200 TDS1000 TDS2000 TPS2000 Series Programmer Manual 3 11 Status and Events The same command sequence using the WAI command for synchronization follows Set up single sequence acquisition SELECT CH1 ON ACQUIRE MODE SAMPLE ACQUIRE STOPAFTER SEQUENCE Acquire waveform data ACQUIRE STATE ON Set up the measurement parameters MEASUREMENT IMMED TYPE PK2PK MEASUREMENT IMMED SOURCE CH1 Wait until the acquisition is complete before taking the measurement WAI Take peak to peak measurement on acquired data MEASUREMENT IMMED VALUE Though WAI is one of the easiest ways to achieve synchronization it is also the most costly The processing time of the oscilloscope is slowed since it is processing a single command at a time This time could be spent doing other tasks The controller can continue to write commands to the input buffer but the commands are not processed by the oscilloscope until all operations in process are complete If the input buffer becomes full the controller will
