IEEE-488.2 Common Commands 6
U2751A Programmer’s Reference Guide 41
*SRE/*SRE?
Syntax
*SRE <enable_value>
This command enables the bits in the enable register for the Status Byte
register group. Once enabled, the corresponding bits may generate a
Request for Service (RQS) in the Status Byte register. This RQS event may
generate a "call back" to your application as a type of asynchronous
interrupt.
*SRE?
The query command reads the enable register and returns a decimal value
that corresponds to the binary-weighted sum of all the bits set in the
register. For example, if bit 2 (decimal value = 4) and bit 6 (decimal value
= 64) are enabled, the query command will return "+68".
Parameter

For more information on the system registers, refer to Chapter 2, “SCPI Status
Registers” on page 9.
Item Type Range of values Default value

binary-weighted sum of the bits in the
register. Refer to the table below.
