Programming the Agilent 603xA Power Supplies Using Basic

Service Request

Service request provides the programmer with the means for interrupting the controller when a fault condition occurs.
Service is requested when the FAU bit in the serial poll register, which is the logical OR of all bits in the fault register,
becomes true with SRQ enabled.

The mask register is used to specify conditions which can cause an interrupt. The fault register can be read to determine
which condition caused an interrupt.

The following commands enable and disable the service request function:

OUTPUT @PS;"SRQ ON"

OUTPUT @PS;~SRQ OFF"

EXAMPLE 7: Enable an interrupt upon a transition to overrange mode. This non-functional example is intended to
show the syntax necessary for setting up an interrupt. A similar sequence of commands can be used to define an
interrupt on any status condition(s) so as to get the controller’s attention as quickly as possible upon transition to a
fault condition.
