Synchronization Methods
Overview
Although most commands are completed almost immediately after being
received by the instrument, some commands start a process that requires time.
For example, once a single sequence acquisition command is executed,
depending upon the applied signals and trigger settings, it may take an extended
period of time before the acquisition is complete. Rather than remain idle while
the operation is in process, the instrument will continue processing other
commands. This means that some operations will not be completed in the order
that they were sent.
Sometimes the result of an operation depends on the result of an earlier operation.
A first operation must complete before the next one is processed. The instrument
status and event reporting system is designed to accommodate this process.
The Operation Complete (OPC) bit of the Standard Event Status Register (SESR)
can be programmed to indicate when certain instrument operations have
completed and, by setting the Event Status Enable Register (ESER) to report
OPC in the Event Status Bit (ESB) of the Status Byte Register (SBR) and setting
the Service Request Enable Register (SRER) to generate service request upon a
positive transition of the ESB, a service request (SRQ) interrupt can be generated
when certain operations complete as described in this section.
The following instrument operations can generate an OPC:

For example, a typical application might involve acquiring a single-sequence
