*SRE
<mask>
*SRE?
*SRE <mask> command sets the value of the enable register in the Status Byte
status group.
*SRE? query returns the value of the enable register in the Status Byte status group.
The Status Byte is used to summarize information from all other status groups.
The enable register specifies which bits in the event register can generate a summary
bit. The instrument logically ANDs corresponding bits in the event and enable
registers, and ORs all the resulting bits to obtain a summary bit. Summary bits are,
in turn, recorded in another register. The standard event status summary bit is
recorded in the Status Byte. Enable registers are read-write. Enable registers are not
affected by *CLS (Clear status). Querying enable registers does not affect them.
The following table describes each bit in the Status Byte status group:
