Description:
The STATus:QUEStionable:CONDition? query reports the contents of the
questionable condition register. Reading a condition register has no effect on its
contents. The decimal value that is returned is the summation of the decimal
value (bit weight) of the individual bits that have been set.
The STATus:QUEStionable:ENABle command sets the contents of the
questionable event enable register. Setting a bit in the event enable register
allows a true condition in the event register to be reported in the summary bit in
the status byte register (STB). If a bit is 1 in the enable register and its associated
event bit transition is true, a positive transition occurs in the questionable
summary bit. After power on, the enable mask is set to 0.
The STATus:QUEStionable? query reports and clears the contents of the
questionable event register. Reading an event register has the effect of clearing
its contents. The decimal value that is returned is the summation of the decimal
value (bit weight) of the individual bits that have been set. After power on, the
contents of the event register is cleared.
The STATus:QUEStionable:NTRansition command sets the contents of the
negative transition filter of the questionable register structure. The negative
transition filter specifies which bits in the questionable condition register, that
make a negative transition (1 -> 0), set the corresponding bit in the questionable
event register.
For example, when you set bit 2 in this filter, it will set bit 2 in the questionable
event register at the time bit 2 in the questionable condition register is reset
(changed from 1 to 0). After power, on the contents of the negative transition filter
is set to #H0000.
