5 Command Reference
Reset
*RST
This command presets the instrument to a factory defined condition that 
is appropriate for remote programming operation. *RST is equivalent 
to performing the two commands :SYSTem:PRESet and *CLS. This 
command always performs a factory preset.
Key access: Preset
Service Request Enable
*SRE <integer>
*SRE?
This command enables the desired bits of the service request enable 
register.
The query returns the value of the register, indicating which bits are 
currently enabled. The default value is 255.
Example: *SRE 16
 enables bits 4 in the service request enable register.
Range: Integer, 0 to 255
Status Byte Query
*STB?
Returns the value of the status byte register without erasing its contents.
Range: Integer, 0 to 255
Example: If a 16 is returned, it indicates that bit 5 is set and one of the conditions 
monitored in the standard event status register is set.
NOTE
The preset performed by *RST is always a factory preset. That is, the 
same preset performed by 
:SYSTem:PRESet when :SYS-
Tem:PRESet:TYPE
 is set to DFT
