Standard Event Status Register
The Standard Event Status register provides general-purpose information
about the instrument. It sets bit 5 in the Status Byte.
Table 5 Standard event status register descriptions
Bit Mnemonic Description
0 Operation Complete Operation Complete bit. It is set in response
to the *OPC command, but only if the
instrument has completed all its pending
operations.
1 Request Control Request Control bit.
2 Query Error Query error bit. It indicates that there is a
problem with the output data queue. There
has been an attempt to read the queue when
it is empty, the output data has been lost, or
the query command has been interrupted.
3 Device Dependent Error Device-dependent error bit. It is set when an
instrument-specific error has occurred.
4 Execution Error Execution error bit. It is set when a
command (GPIB instrument specific) cannot
be executed due to an out of range
parameter or some instrument condition
that prevents execution.
5 Command Error Command error bit. It is set whenever the
instrument detects an error in the format or
content of the program message (usually a
bad header, missing argument, or wrong
data type etc.).
6 User Request User Request bit.
7 Power On Power-on bit. It is set each time the
instrument is powered from off to on.
