Analyze Waveform or Trace Data
4.
On the screen, hollow triangles show the
location of automatic marks and solid
triangles show the custom (user-de
fi
ned)
locations. These appear on both normal and
zoomed waveform views.
5.
You can quickly investigate your waveform
by moving from search mark to search mark
with the next (
→
) and previous (
←
) arrow
buttons. No other adjustments are needed.
Quick tips.
You can copy trigger settings to search for other locations in your acquired waveform that meet the trigger conditions.
You can also copy search settings to your trigger.
Custom (User) marks are saved with the waveform when the waveform is saved and when the setup is saved.
Automatic search marks are not saved with the waveform when the waveform is saved. However, you can easily
recapture them by reusing the search function.
The search criteria are saved in the saved setup.
The Wave Inspector includes the following search capabilities:
Search
Description
Edge
Searches for edges (rising or falling) with a user-speci
fi
ed threshold level.
Pulse Width
Searches for positive or negative pulse widths that are >, <, =, or
≠
a user speci
fi
ed pulse
width.
Timeout
Searches for the lack of a pulse. The signal stays above or below (or either above or
below) a set value for a set amount of time.
Runt
Searches for positive or negative pulses that cross one amplitude threshold but fail to cross
a second threshold before crossing the
fi
rst again. Search for all runt pulses or only those
with a duration >, <, =, or
≠
a user speci
fi
ed time.
Logic
Search for a logic pattern (AND, OR, NAND, or NOR) across multiple waveforms with each
input set to either High, Low, or Don’t Care. Search for when the event goes true, goes
false, or stays valid for >, <, =, or
≠
a user speci
fi
ed time. Additionally, you can de
fi
ne one
of the inputs as a clock for synchronous (state) searches.
Setup & Hold
Search for violations of user speci
fi
ed Setup and Hold times.
