To select the conventional/transitional configuration To specify the sample period The sample rate is the inverse of the sample period. Selecting the State Mode (Synchronous Sampling) To select the state mode You can also select the state sampling mode in the Pod Assignment Dialog on page 175. To select the state speed configuration To set up the sampling clock For the clock input signal that will be used: To automatically adjust sampling positions Page Page To manually adjust sampling positions In Either Timing Mode or State Mode To specify the trigger position To set acquisition memory depth To name an analyzer To turn an analyzer off or on Selecting the Eye Scan Mode To select the eye scan mode To select the eye scan mode speed configuration To set up the eye scan mode reference clock For the clock input signal that will be used: Formatting Labels for Logic Analyzer Probes To assign pods to the analyzer To set pod threshold voltages To set clock threshold voltages To assign probe channels to labels Page To import label names and assignments from a netlist To import label definitions from an ASCII file To export label definitions to an ASCII file To change the label polarity Changing the label polarity will have the following effects: Changing the label polarity does not affect: To reorder bits in a label To turn labels off or on Page Page Setting Up Triggers and Running Measurements Using Trigger Functions To select a trigger function To specify a label pattern event (Timing only) Label pattern events let you specify patterns or ranges on a bus. To specify a label edge event To break down a trigger function (timing or 200 Mb/s state only) Expanded trigger functions can be compressed back into their original form. To create a trigger function library (timing or 200 Mb/s state only) Once you have created a trigger function library with trigger functions, you can: Using Other Trigger Features To count time, states, or turn counting off pod to be left unassigned. To specify default storing Page To specify whether default storing is initially on or off Editing the Trigger Sequence (Timing or 200, 400 Mb/s State Only) To insert/replace/delete sequence levels To cut/copy-and-paste sequence levels To specify a level's goto or trigger action (timing or 200 Mb/s state only) To send e-mail when the trigger occurs (timing or 200 Mb/ s state only) Page To view a picture of the trigger sequence To clear the trigger sequence Editing Advanced Trigger Functions (Timing or 200 Mb/s State Only) To specify a duration or occurrence count for events To insert a store action (state mode) To insert timer actions/events To insert counter actions/events To insert flag actions/events Page To insert a "reset occurrence counter" action To group events To use named events Saving/Recalling Trigger Setups You can save a trigger setup within a session by using trigger save/ recall. To save a trigger setup To recall a trigger setup To clear the trigger save/recall list Running Measurements To start/stop measurements If nothing happens when you start a measurement To view the trigger status Displaying Captured Data To open Waveform or Listing displays To use other display tools Page If the captured data doesn't look correct If there are filtered data holes in display memory To display symbols for data values Page Using Symbols To load object file symbols To adjust symbol values for relocated code To create user-defined symbols To enter symbolic label values When entering label values in the trigger sequence: To create an ASCII symbol file General-purpose ASCII symbol files are created with text editing/ processing tools.
