Set search parameters
From the Analyze menu, select Search; then open the Configure tab.
Overview
Use the controls in these windows to set conditions for the instrument to automatically search and place marks.
To use
The available controls depend on the searches you selected in the Search - Select Control Window.
1. Under Type, click on an entry in the Type-Source table.
2. Set up the controls for each search you want to perform.
3. Click the Search button to On to initiate a search.
Behavior
Refer to the following table for information on automated searches the instrument can perform. The search controls are
functionally similar to the trigger controls.
Search type Description Equivalent trigger
Edge Searches for edges (rising or falling) with
a user-specified threshold level. Edge Trigger Control Window
Glitch Searches for pulses narrower (or wider)
than the specified width, or ignores
glitches narrower (or wider) than the
specified width. Glitch Trigger Control Window
Pattern 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-
specified time. Additionally, you must
define one of the inputs as a clock for
synchronous (state) searches. Serial Pattern Control Window
Pulse Width Searches for positive or negative pulse
widths that are >, <, =, or ≠ a user-
specified pulse width Width Trigger Control Window
Runt Searches for positive or negative pulses
that cross one amplitude threshold but fail
to cross a second threshold before
crossing the first again. Search for all runt
pulses or only those with a duration >, <,
=, or ≠ a user-specified time. Runt Trigger Control Window
Setup and Hold Search for violations of user-specified
setup and hold times. Setup and Hold Trigger Control Window
State Searches for the condition when all logic
inputs to the selected logic function cause
the function to be True or False when the
clock input changes state. Logic State Trigger Control Window
