Status Reporting

This section describes the complete status model of the instrument. Note that some registers are
specific to the GPIB section of the instrument and are of limited use in an RS232 environment.
Standard Event Status and Standard Event Status Enable Registers
These two registers are implemented as required by the IEEE std. 488.2.
Any bits set in the Standard Event Status Register which correspond to bits set in the Standard
Event Status Enable Register will cause the ESB bit to be set in the Status Byte Register.
The Standard Event Status Register is read and cleared by the ∗ESR? command. The Standard
Event Status Enable register is set by the ∗ESE <nrf> command and read by the ∗ESE?
command.

System Event Status Register and System Event Status Enable Register
These two registers are implemented as device specific, event and event enable registers
according to the IEEE Std. 488.2. Their purpose is to inform the controller when the reverse
power protection system is operating or has operated since the last read of the System Event
Status Register.
If the reverse power protection system operates the specified bit will be set in the System Event
Status Register. If the corresponding bit is also set in the System Event Status Enable Register
then the SYS bit will become set in the Status Byte Register.
The System Event Status Register is read and cleared by the SSR? command and the System
Event Status Enable Register is set by the SSE <nrf> command.
The bits are defined as:-
Bit 7 – Bit 1 -
Bit 0 -
Power On. Set when power is first applied to the instrument.
Not used.
Command Error. Set when a syntax type error is detected in a command from
the bus. The parser is reset and parsing continues at the next byte in the input
stream.
Execution Error. Set when an error is encountered while attempting to execute a
completely parsed command. The appropriate error number will be reported in
the Execution Error Register.
Not used.
Query Error. Set when a query error occurs. The appropriate error number will
be reported in the Query Error Register as listed below.
1. Interrupted error
2. Deadlock error
3. Unterminated error
Not used.
Operation Complete. Set in response to the ∗OPC command.
Not used
Set when the reverse power protection system operates
