Monitoring System Operation

Monitoring System Operation

The following program handles two types of service requests. One of them requests service when the analyzer has completed a sweep. The other requests service when an error occurs in the analyzer. When either request is generated, the computer examines the status-byte register using the SPOLL command to determine what caused the service request (end of sweep).

Example Enable multiple service requests. Use HP BASIC command, SPOLL, to examine status byte.
