Instrument Status 8
Condition Register
The Condition Register within the Standard Operation Register Group moni-
tors current conditions regarding the operational state of the instrument. The
Condition Register is read with the command:
STATus:OPERation:CONDition?
Reading the register does not clear the bit(s) in the register. The bit is cleared
when the condition is removed.
Event Register
The Event Register within the Standard Operation Register Group also moni-
tors 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.
