Increment This softkey is displayed only when Save To Trace is selected.

When On, all test violations are saved by incrementing the trace

number. The starting trace number is the one that is currently

selected. When the 64K compressed memory is full, the oldest

trace memory is overwritten, and the trace count continues

incrementing. When the trace count reaches 100, the number

resets to 1 (wraps around).

When Off, only the last test violation is saved, as test failure data is

written over previously stored data.

indications are displayed on the display line as follows.

•

Pass Indicates the displayed waveform passed the test.

•

Fail Indicates the displayed waveform failed the test. Further testing,

and disposition of the failed data is dependent on the testing options

selected.

•

Acquisitions Indicates the total acquisitions made during the test.

•

Failures Indicates the total number (and percentage) of test failures that

occurred during the test.

Waveform Monitoring Operating Hint

Mask template testing can only be used in the Main Horizontal Mode, and when

Functions 1 and 2 are set to off.

The trace review softkey can be used to review all saved failures. See "To Save

or Recall Traces" in this chapter for more information.
