6.3 Common Commands
The common commands are taken from the IEEE 488.2 (IEC 625-2) standard. A particular command
has the same effect on different devices. The headers of these commands consist of an asterisk "*" fol-
lowed by three letters. Many common commands refer to the status reporting system which is described
in detail in chapter “Remote Control – Basics”.
*CAL?
CALIBRATION QUERY initiates a calibration of the instrument and subsequently queries the
calibration status. Any responses > 0 indicate errors.
*CLS
CLEAR STATUS sets the status byte (STB), the standard event register (ESR) and the EVENt-part of
the QUEStionable and the OPERation register to zero. The command does not alter the mask and
transition parts of the registers. It clears the output buffer.
*ESE 0 to 255
EVENT STATUS ENABLE sets the event status enable register to the value indicated. The query form
*ESE? returns the contents of the event status enable register in decimal form.
*ESR?
STANDARD EVENT STATUS QUERY returns the contents of the event status register in decimal form
(0 to 255) and subsequently sets the register to zero.
