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
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. Refer to
for more information.
Parameter
Typical Return
(none)
(none)
Clear event registers, status byte, and error queue: *CLS
*ESE <
value
>
*ESE?
Event status enable command and query. Sets the value in the
for the
group.
Each set bit of the register enables a corresponding event. All enabled events are logically OR-ed into the ESB bit of
the status byte. The query reads the enable register. Refer to
for more information.
Parameter
Typical Return
Decimal sum of the bits in the register, default 0. For example, to enable bit 2 (value 4), bit 3 (value 8), and bit 7 (value
128), use decimal sum 140 (4 + 8 + 128). Default 0.
<
bit value
>
Enable bits 3 and 4 in the enable register: *ESE 24
– The value returned is the binary-weighted sum of all bits set in the register.
– Any or all conditions can be reported to the ESB bit through the enable register. To set the enable register mask,
write a decimal value to the register using
.
– A
does not clear the enable register, but does clear the
