Details
These attributes are used to read or write to the standard event status registers. Reading a status register
returns a value. The binary equivalent of the returned value indicates which register bits are set. The least
significant bit of the binary number is bit B0, and the most significant bit is bit B15. For example, if a value of
1.29000e+02 (which is 129) is read as the value of the condition register, the binary equivalent is
0000 0000 1000 0001. This value indicates that bit B0 and bit B7 are set.

Description
Set bit indicates that all pending selected
instrument operations are completed and the
instrument is ready to accept new commands.
The bit is set in response to an *OPC
command. The opc() function can be used in
place of the *OPC command.
Bit B0 decimal value: 1
Not applicable
Set bit indicates that you attempted to read
data from an empty Output Queue.
Bit B2 decimal value: 4
Set bit indicates that an instrument operation
did not execute properly due to some internal
condition.
Bit B3 decimal value: 8
Set bit indicates that the instrument detected
an error while trying to execute a command.
Bit B4 decimal value: 16
Set bit indicates that a command error has
occurred. Command errors include:
IEEE Std 488.2 syntax error: Instrument
received a message that does not follow the
defined syntax of the IEEE Std 488.2
standard.
Semantic error: Instrument received a
command that was misspelled or received an
optional IEEE Std 488.2 command that is not
implemented.
GET error: The instrument received a Group
Execute Trigger (GET) inside a program
message.
Bit B5 decimal value: 32
Set bit indicates that the LOCAL key on the
instrument front panel was pressed.
Bit B6 decimal value: 64
Set bit indicates that the instrument has been
turned off and turned back on since the last
time this register has been read.
Bit B7 decimal value: 128
