Instrument Status 8
Keysight 53220A/53230A User’s Guide 281
Event Register
The Event Register within the Standard Operation Register Group also monitors
the instrument state. The Event Register is read with the command:
STATus:OPERation[:EVENt]?
Unlike the Condition Register, the bits in the Event Register remain set following
the state that occurred. The bits are cleared by reading the register.
Enable Register
The Standard Operation Register Group Enable Register specifies which bits in the
Event register can generate a summary bit which is subsequently used to
generate a service request.
Bits within the (operational) event register are enabled with the command:
STATus:OPERation:ENABle <enable>
STATus:OPERation:ENABle? (query form)
– enable: decimal value corresponding to the binary-weighted sum of the bits
in the register. For example, to enable the bit monitoring low (critical) battery
charge: STAT:OPER:ENAB 4.
Standard Event Register
The Standard Event Register monitors programming conditions including:
– operation complete
– query errors
– device errors
– execution errors
– command execution errors
– power-on state
Reading the Standard Event Register
The Standard Event Register is read with the command:
*ESR?
Reading the register does not clear the bits. The bits are cleared by sending *CLS.
