Option 298 - 3498A Outguard Decoder00 Id o w e rOn Interrupts with the 3498ANOTEThe following discussion applies only to 3497As with HP-IBcapability. For a 3497A with Serial Data (Option 232),POWER ON SRQ is automatically set.Although both the digital inputlinterrupt assembly (Option 050) and the 100 kHzcounter (Option 060) can cause a digital interrupt when they are placed in a 3497A,they have no interrupt capability when placed in a 3498A. The only interrupt whichcan be generated by the 3498A is POWER ON SRQ.The purpose of the POWER ON SRQ is to provide an indication (when power isreturned) that power has been lost to the 3498A. When the 3498A recovers froma low power cmdition, it sends an interrupt to the 3497A. If the 3497A haspreviously been enabled for POWER ON SRQ, the 3497A will then send an interruptto the controller.Artisan Technology Group - Quality Instrumentation ...
