Issues
The following issues were seen while using a triggered capture with the aforementioned analyzers.
- Panning to the right is restricted to whatever is smaller between the following two situations:
- The region of the window based on the current zoom centered around the final bit parsed by an analyzer.
- When the left edge of the window touches the left edge of the capture (very noticable when using the “Trim pre-trigger data” option).
- Data outside of the “Capture duration after trigger” window is still parsed and displayed.
Steps to Reproduce
- Enable required digital channels to analyze UART or SPI.
- Configure the analyzer to work with the selected digital channels.
- Select “Trigger” as your capture type.
- Set the “Pattern and Channel” setting to detect a falling edge of either the UART RX or the SPI CSN digital channel.
- Set the “Capture duration after trigger” setting to something like “20 ms”.
- Set the “Trim pre-trigger data” value to something like “1 ms”.
- Start the capture.
- Send a single byte of data.
- Notice the following:
- The duration of the capture after the trigger is reduced to a few milliseconds.
- Panning to the right stops once the left side of the window touches the start of the trimmed data.
- Zooming toward the right side of the capture is centered around the final bit of data analyzed and gets smaller as you zoom in.
- Start the capture again.
- Send a stream of bytes that would exceed the configured capture duration.
- Notice the following:
- The analyzer still displays the data that was captured outside of the configured “Capture duration after trigger” setting.
- Zooming in is still centered around the final bit of data analyzed but now extends past the actual signal displayed.
