Non-monotonic Mode
Non-monotonic Mode looks for edges that cross a threshold more than once between high and low levels.
All events that meet the criteria of slope, hysteresis, and level are presented in a table and highlighted in
the source trace. The value displayed in the table is the difference of the max. and min. of the non-
monotonicity. This can be confirmed with cursors. The hysteresis value is used to eliminate noise. A non-
monotonicity is detected only when its amplitude is greater than the hysteresis. Therefore, when setting a
hysteresis level, set a value that is greater than the amplitude of the noise. Settings are:
l Slope. Choose Pos, Neg, or Both.
l Hysteresis is (set in...). Choose Division, Percent, Absolute.
l Division/Percent/Absolute. Enter hysteresis level in the selected unit.
l Levels are (set in...). Choose Percent, Absolute, or Pk-Pk%.
l High/Low Level. Enter top and bottom thresholds in the selected unit.
Runt Mode
Runt Mode looks for pulses that fail to cross a specified threshhold. You can search for positive-going or
negative-going runts, or both. An adjustable hysteresis band is provided to eliminate noise.
In the case of negative-going runt pulses, the value displayed in the table is the difference (delta) of the
high level of the signal and the runt amplitude (i.e., where the runt bottoms out). This can be confirmed by
placing cursors on the runt pulse and reading the delta Y value in the trace labels. In the case of positive-
going runt pulses, the value displayed in the table is the absolute value of the amplitude of the runt pulse.
Runt Mode settings are:
l Runt Type. Choose Both, Pos, or Neg.
l Hysteresis. Enter the hysteresis level as a percentage or voltage.
l Low/High Threshold. Enter the levels as a percentage or voltage.
l Absolute Levels. Check this box to enter levels as absolute voltage instead of percentage.
Measurement Mode
Measurement Mode is used for applying filters to measurements to find those that meet your defined
criteria, helping to isolate particular events within many samples. Markers appear over the source trace to
indicate the location of measurement, while the table displays values for the selected parameter that
meet the criteria. Measurement Mode settings are:
l Measurement. Choose the measurement parameter you wish to search.
l Filter Method. Choose the operator that indicates the desired relationship to the Filter Limit. Only
measurements that meet this criteria are returned.
l Filter Limit. Enter the value that completes the filter criteria.
Alternatively, you can use the Filter Wizard to create the filter criteria.
