2 Using the Agilent 82357B
SRQ operation
If your VISA/SICL application uses SRQ callbacks
(
viEventHandler() in VISA or ionsrq() in SICL) and your
callback does not service the SRQ in a timely manner, your
SRQ callback function may be triggered multiple times.
To avoid this possible situation, design your SRQ callback
functions to be called only when an SRQ is no longer
asserted on the GPIB bus.
