To select the full/half channel 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 130. To select the 200 MHz/400 MHz state speed configuration To change the sampling clock mode Page To set up the sampling clock To automatically adjust sampling positions Page Page To manually adjust sampling positions Page (The actual sampling position is in the middle of the setup/hold window.)

Label edge events let you specify edges and glitches on a bus. Label To specify a label edge event edge events are only available in certain timing mode trigger functions. To break down a trigger function To create a trigger function library Page Using State Mode Trigger Features To count states or time To Specify Default Storing To specify whether default storing is initially on or off Editing the Trigger Sequence To insert/replace/delete sequence levels To cut/copy-and-paste sequence levels To specify a level's goto or trigger action To send e-mail when the trigger occurs Page the protocol. On the Internet, there are the following TCP/IP protocols: To view a picture of the trigger sequence To clear the trigger sequence Editing Advanced Trigger Functions To specify a duration or occurrence count for events (timing mode) 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 event list, you can specify their evaluation order by grouping the events. To use named events Saving/Recalling Trigger Setups To save a trigger setup To recall a trigger setup To clear the trigger save/recall list Running Measurements After you set up a trigger, you're ready to run the logic analyzer measurement. 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 display Timing Zoom data 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 To cancel the display processing of captured data You can cancel the processing of captured data if it is taking too long. 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. To create a readers.ini file If a file only has an ELF section this will have no effect and the ELF This option must be specified in the Nsr section of the Readers.ini file: Page Page Printing/Exporting Captured Data Page Cross-Triggering To cross-trigger between two analyzers To cross-trigger with another instrument Solving Logic Analysis Problems To test the logic analyzer hardware Page Saving and Loading Logic Analyzer Configurations Page Page Page Page The Sampling Tab Timing Mode When you select Timing Mode, the Timing Mode Controls area appears.
