*SRE
Description
The *SRE command sets the Service Request Enable register (SRE). This command allows you to specify
which summary message bit or bits in the STB register generate a service request. Refer to the table on
page 225 for an overview of the available summary messages.
A summary message bit is enabled by writing a 1 into the corresponding bit location. Conversely, writing a
0 into a given bit location prevents the associated event from generating a service request (SRQ). Clearing
the SRE register disables SRQ interrupts.
The *SRE? query returns a value that, when converted to a binary number, represents the bit settings of
the SRE register. Note that bit 6 (MSS) cannot be set and its returned value is always zero.
Command Syntax
*SRE <value>
<value>:= 0 to 255
Query Syntax
*SRE?
Response Format
*SRE <value>
Example (GPIB)
The following instruction allows an SRQ to be generated as soon as the MAV summary bit (bit 4, for
example decimal 16) or the INB summary bit (bit 0, for example decimal 1) in the STB register, or both, are
set. Summing these two values yields the SRE mask 16 + 1 = 17.
