Condition Register
A condition register continuously monitors the hardware and firmware
status of the Counter. There is no latching or buffering for this register; it
is updated in real time. Reading a condition register does not change its
contents.
To read the condition registers use:
:STATus:OPERation:CONDition?
:STATus:QUEStionable:CONDition?
Transition Filter
A transition filter specifies the transition criteria for setting event bits
TRUE.
When the transition filter specifies a positive transition, the event
becomes TRUE when its associated condition makes a FALSE to TRUE
transition only.
When the transition filter specifies a negative transition, the event
becomes TRUE when its associated condition makes a TRUE to FALSE
transition only.
When the transition filters specify both a positive and a negative
transition, the event becomes TRUE when its associated condition makes
either a FALSE to TRUE or a TRUE to FALSE transition.
A transition filter is defined by positive and negative transition filter
registers. Table 3-6 describes how the transition filter registers define the
transition criteria for setting an event bit TRUE.
