16. 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 MSS bit
when an event such as a current limit occurs. When the MSS bit is set, your program can
then act on the event in the appropriate fashion.

Figure 16-1 shows the status register structure of the AC source.
The Standard Event, Status Byte, and Service Request Enable registers and the Output
Queue perform standard IEEE-488 functions as defined in the IEEE 488.2 Standard Digital
Interface for Programmable Instrumentation.
16.1. Power-On Conditions
Refer to the *RST command description in paragraph 14.4.6 for the power-on conditions of
the status registers.
