14.3 Commands
*ESE
Function
Sets the value for the standard event enable
register, or queries the current setting.
Syntax
*ESE {<NRf>}
*ESE?
{<NRf>}=0 to 255
Example
*ESE 253
*ESE?
→
253
Description
• Each bit is expressed as a decimal number.
• For example, if “
*ESE 253
” is set, the
standard enable register will be set to
“
11111101
”. This means that bit 2 of the
standard event register is disabled so that bit
5 (ESB) of the status byte register will not be
set to “
1
”, even if a query error occurs.
• Default is “
*ESE 255
” , i.e. all bits are
enabled.
• The standard event enable register will be
cleared when an inquiry is made using
*ESE?
.
• For details referring the standard event
enable register, see section 14.4.
