OPC : Operation Complete. Set by the *OPC command.
INP : Input bu er error. Indicates data has been discarded from the
input bu er.
QYE : Query Error. Indicates data in the output queue has been lost.
DDE : Device-Dependent Error. Indicates a failed autocalibration.
EXE : Execution Error. Indicates the error in a command that was
successfully parsed. Out-of-range parameters are an example.
CME : Command Error. Indicates a command parser-detected error.
URQ : User Request. Indicates that a front-panel button was pressed.
PON : Power On. Indicates that an o -to-on transition has occurred.
The ESE acts as a bitwise AND with the ESR register to produce the
single-bit ESB message in the Status Byte Register (SB). The register
can be set and queried with the *ESE(?) command.
At power-on, this register is cleared.
The Communication Error Status Register consists of 8 event flags;
each of the flags is set by the corresponding event, and cleared only
by reading the register or with the *CLS command. Reading a single
bit (with the CESR? i query) clears only Bit i.
