Status Reporting Structure

This section provides information about the status reporting structure for Service Request
functions which correspond to SCPI.
Figure 5-2. Status Reporting Structure
Service Request (SRQ)
The 4349B can send an SRQ (Service Request) control signal when it requires the controller
to perform a task. When the 4349B generates an SRQ, it also sets Bit 6 of the status byte,
RQS (Request Service) bit. Service Request Enable Register allows an application programmer
to select which summary messages in the status byte register may cause service requests.
(Illustrated in Figure 5-3.)
