Status Reporting Structure of B2200

The above figure shows Service Request Generation. When a condition occurs that requires service, the instrument sets Request Service bit (RQS − bit6) of Status Byte, and sends a Service Request (SRQ) via GPIB bus to the controller. So, the controller can execute an interrupt service routine (must be in the program) that uses a Serial Poll to read Status Byte of each instrument to determine which instrument requested service. See “Status Byte Register” on page 5-55.
