Setting up an SRQ Interrupt
Setting up an SRQ Interrupt
The Test Set provides many status bits which can be read directly or used to
generate SRQ interrupts. For example, the following front panel annunciators
have assigned status bits:
•
Transmitting
•
Registering
•
Page Sent
•
Access Probe
•
Connected
•
Softer Handoff
•
Hard Handoff
Using SRQ interrupts requires more program code than requesting status at
different time intervals (polling), but SRQ interrupts have the advantage of
allowing the Call Processing Subsystem to operate at its maximum speed since
processes within the subsystem are not constantly interrupted by commands on
the GPIB.
