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.
