*SRE
Syntax *SRE <enable value>
*SRE?
Description Enable the bits in the enable register of the status byte register.
Query the bits currently enabled in the enable register of the status byte register.
Parameter Name Type Range Default
<enable value> Discrete Refer to the "Explanation" None
Explanation  <enable value> is a decimal value corresponding to the sum of the binary
weights of the bits to be enabled in the status byte enable register. For the
definitions of the bits in the status byte register and their corresponding
decimal values, please refer to Table 1-6.
For example, to enable the bit3 (QUES) and bit4 (MAV) in the status byte
enable register, set <enable value> to 24 (according to 2 3 +2 4 =24).
 After the bits are enabled, the system sends service request via the bit6
(service request bit) in the status byte register.
 When <enable value> is set to 0, executing this command will clear the enable
register of the status byte register. You can also send the *PSC command
(*PSC 1) to clear the enable register of the status byte register at the next
power-on.
Return Format The query returns a decimal value corresponding to the sum of the binary weights
of the bits enabled in the status byte enable register, for example, 24.
Example *SRE 24 /* Enable the bit3 (QUES) and bit4 (MAV) in the enable register of the
status byte register and enable the service request*/
*SRE? /* Query the bits currently enabled in the enable register of the status
byte register and the query returns 24*/

Command
*PSC
*STB?
Syntax *STB?
Description Query the SUMMARY register of the status byte register.
Explanation The query returns a decimal value (corresponding to the sum of the binary weights
of all the bits in the register) but do not clear the register. For the definitions of the
bits in the status byte register and their corresponding decimal values, please refer
to Table 1-6.
For example, if questionable state currently occurs in the instrument and the service
request is send, the bit3 (QUES) and bit6 (RQS) in the SUMMARY register of the
status byte register are set and the query returns 72 (according to 2 3 +2 6 =72).
Return Format The query returns a decimal value corresponding to the sum of the binary weights
of all the bits in the SUMMARY register of the status byte register, for example, 72.
Example *STB? /* Query the SUMMARY register of the status byte register and the query
returns 72*/
