3 - Programming the DC Source

Programming the Status Registers
You can use status register programming to determine the operating condition of the dc source at any
time. For example, you may program the dc 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 3-7 shows the status register structure of the dc source. Table 3-1 defines the status bits. The
Standard Event, Status Byte, and Service Request Enable registers and the Output Queue perform
standard GPIB functions as defined in the
IEEE 488.2 Standard Digital Interface for Programmable
Instrumentation. The Operation Status and Questionable Status registers implement functions that are
specific to the dc source.
Power-On Conditions
Refer to the *RST command description in chapter 4 for the power-on conditions of the status registers.
