SCPI command terminators
A command string sent to the instrument must terminate with a <new line> character. The IEEE-488.2
EOI (end-or-identify) message is interpreted as a <new line> character and can be used to terminate
a command string in place of a <new line> character. A <carriage return> followed by a <new line> is
also accepted. Command string termination will always reset the current SCPI command path to the
root level.
Common commands
Common commands (summarized in Common command summary (on page 5-4)) are device
commands that are common to all devices on the bus. These commands are designated and defined
by the IEEE-488.2 standard. Most of these commands are described in detail in this section.
Common command summary
The following table lists the IEEE-488.2 common commands used by the instrument.
Mnemonic Name Description
*CLS Clear status Clear the Status Byte Summary Register and all
event registers.
*ESE <NRf> Event enable command Enable bits in the Standard Event Enable Register.
The selected bits are then reported to the Status
Byte.
*ESE? Event enable query Query the Standard Event Enable Register. The
instrument returns a decimal value that
corresponds to the binary-weighted sum of all bits
set in the register.
*ESR? Event status register query Query the Standard Event Status Register. The
instrument returns a decimal value that
corresponds to the binary-weighted sum of all bits
set in the register.
*IDN? Identification query Returns the manufacturer, model number, serial
number, and firmware revision levels of the
instrument.
*OPC Operation complete command This command sets the OPC bit.
*OPC? Operation complete query Returns “1” to the output buffer after the command
is executed.
*PSC <b> Power-on status clear Clear the Status Byte and Standard Event Register
enable masks when power is turned on (*PSC 1).
When *PSC 0 is in effect, the Status Byte and
Standard Event Register enable masks are not
cleared when power is turned on. [Stored in
nonvolatile memory].
*PSC? Power-on status clear query Query the power-on status clear setting. Returns
“0” (*PSC 0) or “1” (*PSC 1).
*RST Reset command Reset the instrument to the power-on configuration.
*SRE <NRf> Service request enable
command Enable bits in the Status Byte Enable Register.
*SRE? Service request enable query Query the Status Byte Enable Register.
*STB? Status byte query Query the Status Byte Summary Register.
*TRG Trigger command Sends a bus trigger to the instrument.
