IEEE-488.2 Common Commands 13
Keysight U2722A/U2723A Programmer’s Reference 121
*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. 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 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
Item Type Range of values Default value
<enable_value> NRf A decimal value that corresponds to the binary-weighted sum
of the bits in the register. Refer to the table below.
This is a required
parameter.
