Service Request Enable Register
This register is programmed by the user and is used to enable or disable the setting of bit B6
(RQS/MSS) by the Status Summary Message bits (B0, B1, B2, B3, B4, B5, and B7) of the Status
Byte Register. As shown in the
(on page D-7) topic, a logical AND
operation is
performed on the summary bits (&) with the corresponding enable bits of the Service Request Enable
Register. When a logical AND
operation is performed with a set summary bit (1) and with an enabled
bit (1) of the enable register, the logic “1” output is applied to the input of the logical OR gate and,
therefore, sets the MSS/RQS bit in the Status Byte Register.
The individual bits of the Service Request Enable Register can be set or cleared by using the
*SRE
common command. To read the Service Request Enable Register, use the
*SRE?
query. The Service
Request Enable Register clears when instrument power is cycled or a parameter value of 0 is sent
with a status request enable command (for example,
*SRE 0
is sent). You can program and read the
SRQ Enable Register using the following commands.
