What Are Status Register SCPI Commands
Most monitoring of the instrument conditions is done at the highest level using the IEEE
common commands indicated below. Complete command descriptions are available in the
IEEE commands section at the beginning of the language reference. Individual status
registers can be set and queried using the commands in the STATus subsystem of the
language reference.
• *CLS (clear status) clears the status byte by emptying the error queue and clearing all
the event registers.
• *ESE, *ESE? (event status enable) sets and queries the bits in the enable register part
of the standard event status register.
• *ESR? (event status register) queries and clears the event register part of the standard
event status register.
• *OPC, *OPC? (operation complete) sets the standard event status register to monitor
the completion of all commands. The query stops any new commands from being
processed until the current processing is complete, then returns a '1'.
• *PSC, *PSC? (power-on state clear) sets the power-on state so that it clears the service
request enable register and the event status enable register at power on.
• *SRE, *SRE? (service request enable) sets and queries the value of the service request
enable register.
• *STB? (status byte) queries the value of the status byte register without erasing its
contents.
