7. Status Registers
You can use status register programming to determine the operating condition of the AC
source at any time. For example, you may program the AC source to generate an interrupt
(assert SRQ) when an event such as a current limit occurs. When the interrupt occurs, your
program can then act on the event in the appropriate fashion.
Figure 7-1 shows the status register structure of the AC/DC source. Table 5-1 defines the
status bits. The Standard Event, Status Byte, and Service Request Enable registers as well
as the Output Queue perform standard IEEE-488 functions as defined in the IEEE 488.2
Standard Digital Interface for Programmable Instrumentation. The Operation Status, and the
Questionable Status registers, implement functions that are specific to the AC/DC source.
7.1 Power-On Conditions
All status register groups are cleared at power on. This means all data bits and all Event
Enable register bits are cleared. It is possible however the set the PON mask in the Event
enable register to cause a SRQ. This can be accomplished using the *PSC command. Once
set, this condition is retained in non-volatile memory and will be recalled when power is
applied to the AC/DC source. See paragraph 5.7 for details on the use of the *PSC
command.
7.2 Operation Status Group
The Operation Status group records signals that occur during normal operation. The group
consists of the following registers:
Register Command Description
Condition STAT:OPER:COND? A register that holds real-time status of the
circuits being monitored. It is a read-only
register.
Event STAT:OPER:EVEN? A register that latches any condition. It is a
read-only register that is cleared when read.
Enable STAT:OPER:ENAB A register that functions as a mask for
enabling specific bits from the Event register.
It is a read/write register.
Table 7-1: Operation Status Register
The outputs of the Operation Status register group are logically-ORed into the OPER(ation)
summary bit (7) of the Status Byte register.
