Chapter 3: Using the Logic Analyzer in Timing or State Mode
Setting Up Triggers and Running Measurements
Group Run Repetitive, or Run All button.
Run starts only the instrument you are using. Single runs gather data
until the logic analyzer memory is full, and then stop.
Repetitive runs keep repeating the same measurement and are
useful for gathering statistics.
Group Run (or repetitive group run) starts all instruments attached
to group run in the Intermodule window.
Run All starts all instruments currently placed in the workspace.
To stop a measurement
1. Select the Stop or Stop All button.
If nothing happens when you start a measurement
• Analyzers with deep memory take a noticeable amount of time to complete
a run. Because data is not displayed until acquisition completes, it may
look like nothing is happening. Check the Run Status window to see if the
logic analyzer is still running.
• Messages such as "Waiting in level 1" may indicate you need to refine your
trigger.
• If the status shows as "Stopped", the analyzer either finished the
acquisition, or was unable to run. The cause of the problem is listed in the
bottom half of the Run Status window.
• Look for an error message in the message bar at the top of the window.
Common messages are "slow or missing clock" and "Waiting for trigger".
• If Run briefly changed to Stop or Cancel, select the Window menu,
choose the logic analyzer's slot, then choose the Waveform or Listing
display.
