Caused by a Memory Allocation failure. The
measurement limited the acquisition time in order to
complete the measurement.
(23) Setup INVALID
The parameters chosen create a measurement request
that is impossible to complete, often due to memory
limitations.
(24) External reference missing
The external frequency reference signal either is
missing, has too low an amplitude, or does not match
the frequency value previously entered into the
instrument memory by the operator.
(25) Even Second Clock missing
