Status Structure
The commands to read the condition registers are listed in Table 13-4. For details on reading
registers, see “Reading registers”.
Event registers
As Figure 13-1 shows, each status register set has an event register. When an event occurs,
the appropriate event register bit sets to 1. The bit remains latched to 1 until the register is reset.
Reading an event register clears the bits of that register. *CLS resets all four event registers.
The commands to read the event registers are listed in Table 13-5. For details on reading reg-
isters, see “Reading registers”.

Common and SCPI commands — condition registers
Command
Description
STATus
STATus subsystem:
:OPERation:CONDition?
Read operation condition register.
:MEASurement:CONDition?
Read measurement condition register.
:QUEStionable:CONDition?
Read questionable condition register.

Common and SCPI commands — event registers
Command
Description
*ESR?
Read standard event status register.
STATus
STATus subsystem:
:OPERation:[:EVENt]?
Read operation event register.
:MEASurement:[:EVENt]?
Read measurement event register.
:QUEStionable:[:EVENt]?
Read questionable event register.
Note: Power-up and *CLS resets all bits of all event registers to 0. STATus:PRESet has no
effect.
