Status RegistersThe programmable power supplies use status registers that are
defined by SCPI, IEEE-488.1, and IEEE-488.2 standards.
SCPI Status Registers
The power supplies include two status registers defined by the SCPI
standard:
HOPERation Status Registers (CONDition, EVENt, and ENABle)
HQUEStionable Status Registers (CONDition, EVENt, and
ENABle)
The STA Tus subsystem (Figure 8) is the hierarchical set of
commands that read the SCPI defined status registers.
Figure 8: STATus Hierarchy of SCPI Defined Registers
The lower-level nodes :OPERation and :QUEStionable each have
three 16-bit registers: CONDition, EVENt, and ENABle. Figure 9
shows the sequential relationship between these three types of
registers and the commands that relate to each register.
