22 82357B User’s Guide
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.
NOTE
• You can change the parameter values of the 82357B as required. See
“Changing configuration parameters” on page 23 for details.
• You can also convert from multiple mode operation to single mode
operation. See “Changing modes of operation” on page 24 for details.
