Service request
The generation of a service request is controlled by the Status Byte Enable Register. This register is
programmed by you and is used to enable or disable the setting of bit B6 (RQS) by the Status
Summary Message bits (B2, B3, B4, and B5) of the Status Byte Register. The summary bits are
logically ANDed (&) with the corresponding enable bits of the Status Byte Enable Register. When a
set (1) summary bit is ANDed with an enabled (1) bit of the enable register, the logic “1” output is
applied to the input of the OR gate, and then sets the RQS bit in the Status Byte Register.
The individual bits of the Status Byte Enable Register can be set or cleared by using the *SRE
common command. To read the Status Byte Enable Register, use the *SRE? query command. The
Status Byte Enable Register clears when power is cycled or a parameter value of 0 is sent with the
*SRE command (for example, *SRE 0). The commands to program and read the SRQ Enable
Register are described in Status byte and service request commands (on page B-7
).
If you have set the instrument previously by using *PSC 0, the Status Byte Enable Register will not
be cleared at power-on.
