  • Page 459: Preventing Overlapping Execution

    Remote Control Basics R&S ® SMJ100A Command Sequence and Synchronization As a general rule, send commands and queries in different program messages. Example: Overlapping command with *OPC The instrument implements INITiate[:IMMediate] as an overlapped command. Assuming that INITiate[:IMMediate] takes longer to execute than *OPC, sending the following command sequence results in initiating a sweep and, after some time, set- ting the OPC bit in the ESR: INIT;...
  • Page 460 Remote Control Basics R&S ® SMJ100A Command Sequence and Synchronization Command synchronization using *WAI or *OPC? appended to an overlapped command is a good choice if the overlapped command takes only little time to process. The two synchronization techniques simply block overlapped execution of the command. For time consuming overlapped commands it is usually desirable to allow the controller or the instrument to do other useful work while waiting for command execution.

The serial poll method is defined in IEEE 488.1 and used to be the only standard possi- bility for different instruments to poll the status byte.
