*CLS
The Clear Status command clears status data structures and forces the device to the
Operation Complete Keyword Idle state.
*ESE
<value>
The Standard Events Status Enable command sets the Standard Events Register
bit.
The
numeric value is entered as a decimal value between 0 and 255.
*ESE?
The Standard Events Status Enable Status query allows you to read the current
contents
of
the Standard Event Status EnabIe Register. The device returns a value
between
0 and 255.
*ESR?
The Standard Event Status Register query allows you to read the current contents
of
the Standard Event Status Register. Reading this register clears it.
*IDN?
The Identification query returns the following information: Manufacturer, Model,
SeriaI number, and Firmware level.
*OPC
The Operation Complete command causes the device to generate the operation
complete message in the Standard Event Status Register when all pending select
device operations have been finished.
*OPC?
The
Operation
Complete
query places
an
ASCII
character 1 into the device's
Output Queue after finishing all pending selected device operations.
*RCL<value>
The Recall command causes the instrument setup state to go to the setup last stored
with *SA
V <value>
or
with MMEM:STOR:SET <value>, where <value> is the
Stored Setting number from
0 to 32,767.
The
file name used is "Snnnnn", where
"nnnnn" is the 5-digit string corresponding to <value>.
*RST
Places the instrument in its power-on-reset state.
AlI
outputs are turned offand all
parameters are retumed to their default values. This command does not affect the
TRACe subsystem.
*SAV
<value>
The Save cornmand stores the current instrument setup state as a Stored Setting,
where <value> is the Stored Setting number from
0 to 32,767. This setup

be
restored to the instrument with the *RCL <value>
or
with MMEM:LOAD:SET
<"Snnnnn">. The file
name
created is "Snnnnn", where
"nnnnn"
is
the 5-digit
string corresponding to <value>.
*SRE
<value>
The Service Request Enable cornmand sets the Service Request EnabIe Register
