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.
