On Fail, Save Softkey
The on fail, save softkey saves the data associated with the failure
(from selected channel, function, or screen) to memories or to a hardcopy
device. You can select the source and destination of the save by pressing the
softkey until the desired parameter is highlighted, then by turning the entry
knob to change selections. The source choices include any channel, function,
or the screen. The destination choices include off (not saved), waveform
memories, multiple memories, pixel memories, and hardcopy. The
destination choices available depend on the source currently selected:
e Channel — off, nonvolatile memories, or multiple
e Function — off, nonvolatile memories, or multiple
e Screen — off, pixel memories, or hardcopy.
The type or amount of failure data saved depends on the destination selected.
If a destination is selected and the channel or function is off, a message is
displayed indicating that the data is invalid and failure data is not stored.
When saving to a waveform memory, you can select one memory. Selection
of the memory pair containing the comparison waveform is not allowed. If
multiple failures occur, only the last failure data is saved because the most
current data overwrites the memory contents. However, as each source is
saved to that memory, the previous contents are overwritten. If a waveform
memory is set to protected, the message "protect on: cannot store to
memory" is displayed and the data is not saved.
When saving to multiple memories, you can save up to 665 records (data
includes a time/date stamp). If multiple failures occur and the stop after fail
mode is selected, then the test terminates after all available memory space is
filled. If the continue after fail mode is selected, after the 665 memories are
filled, the data records wrap around and new data overwrites previous data.
If more than one source is specified with a multiple destination, then the data
records are partitioned between the specified sources.
