Standard Event Registers
Operation Complete (bit 0)
This bit is set in response to the *OPC command. It indicates that the instrument has completed all
pending operations.
This works for IEEE only - the bit is indeterminate for RS-232.
Query Error (bit 2)
This bit is set when either an attempt has been made to read data from the output queue when no
data is present or pending, or data in the queue has been lost.
This works for IEEE only - the bit is indeterminate for RS-232.
Execution Error (bit 4)
This bit is set when a valid command has been received and recognised, but could not be executed
at the time. This could be either an out-of-context command or an out of range parameter. The
command is ignored.
Command Error (bit 5)
This bit is set when the command line is not recognised by the parser. This could be an invalid
command, parameter or syntax. The command is ignored.
Power On (bit 7)
Indicates that an off-on transition has occurred in the instrument’s power supply.
The following commands are used to access these registers;
*ESR?
Query the Standard Event Register. The instrument returns a decimal value which corresponds to
the binary-weighted sum of all bits set in the register, and clears it.
*ESE <enable value>
Enable bits in the Standard Event Enable Register. The selected bits are then reported to the Status
Byte.
*ESE?
Query the Standard Event Enable Register. The instrument returns a decimal value which
corresponds to the binary-weighted sum of all bits set in the register.
