11.8.6. Read the Status Byte Register
The Status Byte register is a summary of all events that have been enabled. Figure 7
shows the commands that are used to enable events. The Status Byte is a condition
register, that is, reading it will not clear the contents. To clear the Status Byte register,
the connected event registers must be read or cleared.
These are the bit assignments of the Status Byte:
BIT VALUE
0 1
1 2
2 4
3 8
4 16
5 32
6 64
7 128
Syntax:
Response: <nnn>, a number from 0 to 255
Example:
11.8.7. Set the Service Request Enable Register
The IEEE-488.2 specification defines this register so instruments may generate a
service request when selected events occur.
The Genesys™ power supply LAN option does not support the service request
feature, so the *SRE command has no effect.
Syntax:
Parameter: <nnn>
Example:
Query:
8303460000 Rev A

*STB?
12 (a supply fault had occurred and there is some error which may be
read using the SYSTEM:ERROR? query)
*SRE <nnn>
is a number from 0 to 255. The bit assignments are the
same as the Status Byte, in the table above
*SRE 255
will cause Status Byte bits 2, 3, 5 and 7 to be set
*SRE?
will return 172 in the example
(bits 0,1,4 and 6 are not settable in the *SRE register)
