IEEE-488/SERIAL INTERFACE COMMANDS (ALPHABETICAL LISTING)
Q
CLS
Clear Interface Command
Input:
Q
CLS
Returned:
Nothing
Remarks:
Clears bits in the Status Byte Register and Standard Event Status Register and terminates all
pending operations. Clears the interface, but
not
the instrument. See
Q
RST
command.
Q
ESE
Configure Status Reports in the Standard Event Status Register
Input:
Q
ESE <bit weighting>
Returned:
Nothing
Remarks:
Each bit is assigned a bit weighting and represents the enable/disable status of the
corresponding event flag bit in the Standard Event Status Register. To enable an event flag
bit, send the command
Q
ESE
with the sum of the bit weighting for each desired bit. See the
Q
ESR?
command for a list of event flags.
Example:
To enable event flags 0, 3, 4, and 7, send
*ESE 143[term]
. 143 is the bit weighting sum for each bit.
