Transition filters are unaffected by *CLS or queries. Transition filters are set to
default values by :STATus:PRESet and power-on.
To write to the transitions filter registers use:
:STATus:OPERation:PTRansition
:STATus:OPERation:NTRansition
:STATus:QUEStionable:PTRansition
:STATus:QUEStionable:NTRansition
To read the transition filter registers use:
:STATus:OPERation:PTRansition?
:STATus:OPERation:NTRansition?
:STATus:QUEStionable:PTRansition?
:STATus:QUEStionable:NTRansition?
Event Register
An event register captures changes in conditions.
An event register bit (event bit) shall be set TRUE when an associated event
occurs. These bits, once set, are “sticky.” That is, they cannot be cleared even if
they do not reflect the current status of a related condition, until they are read.
To read the event registers use:
:STATus:OPERation[:EVENt]?
:STATus:QUEStionable[:EVENt]?
Use event register queries or *CLS to clear event registers.
Event Enable Register
An event enable register selects which event bits in the corresponding event
register can generate a summary bit.
To write the event enable registers use:
:STATus:OPERation:ENABle
:STATus:QUEStionable:ENABle
To read the event enable registers use:
:STATus:OPERation:ENABle?
:STATus:QUEStionable:ENABle?
The event enable registers are cleared by :STATus:PRESet and power-on .
