OPERation Status Register
The operation status register is a standard SCPI, 16-bit register which
contains information about conditions which are part of the power
supply's normal operation. The Operation Status data structure has the
operation status register and two sub-registers to represent shutdown and
protection shutdown. Each of the sub-registers is summarized in a
summary bit.
Figure 5-22 represents the Operation Status data structure. The “+”
represents the logical summation/or of bits in a register. Table 5-11, Table
5-12, and Table 5-13 describe the meanings of each bit as well as the bit
number and bit weight.
