Condition Errors 36 to 64, Calibration Needed or Failed
This series of errors corresponds to the bits in the
STATus:QUEStionable:CALibration register. The second column in the table
shows the corresponding bit.
An event with the error number shown in the table means the condition has
been detected. When the condition is cleared, an event with the error number
plus 1000 is generated. These error numbers can be seen in the Show Errors
screen, along with the DETECTED and CLEARED indicators.
For example, error 42 indicates that the “RF Alignment Failure” condition has
been detected, and error 1042 indicates that failure has been cleared.
Several bits in this register are “summary bits” for registers at a lower level.
There are no error messages associated with these bits; they exist only as
status bits, read with a STATus:QUEStionable:CALibration? event query or a
STATus:QUEStionable:CALibration:CONDition? query.
Note that these summary bits summarize the state and history of the event
registers at the lower level. This is true even for bits in the
STATus:QUEStionable:CALibration condition register. This means that:
The summary bits read by the STATus:QUEStionable:CALibration:CONDition?
query are true if any event bits are set in any of the :CALibration sub-registers
:SKIPped, :EXTended:NEEDed or :EXTended:FAILure.
The summary bits read by the STATus:QUEStionable:CALibration? event query
are true if any event bit has undergone a false-to-true transition with the
PTRansition filter set, or a true-to-false transition with the NTRansition filter
set, in any of the :CALibration sub-registers :SKIPped, :EXTended:NEEDed or
:EXTended:FAILure.
