Chapter 4 IEEE-488 Common Commands
IEEE-488 Common commands generally control overall instrument functions,
such as reset, status, and synchronization. All common commands consist of a
three-letter mnemonic preceded by an asterisk:
*RST *IDN? *SRE 8
.
*CLS
Clear Status Command. Clears the event registers in all register groups. Also
clears the status byte and error queue. If *CLS immediately follows a program
message terminator (<NL>), then the output queue and the MAV bit are also
cleared.
Syntax:
*CLS
Arguments:
None
*ESE
Event status enable command. Sets the value in the enable register for the
Standard Event Status group. Each set bit of the register enables a
corresponding event. All enabled events are logically ORed into the ESB bit of
the status byte.
Syntax
*ESE <NR1>
Arguments
0
～
255
The value returned is the binary-weighted sum of all bits set in the register.
Default value
See *PSC.
Example
*ESE 128
