## Trimming Capture Files
1. Open a capture file. You should hopefully see a trimmable region in the IQ Display control.
- If you don't see a block in the IQ Display, the capture signal was too weak for the tool.
2. Manually set Start/End or use the Cutoff % to automatically trim.

## Splitting Capture Files
Capture files can be split into multiple files using FileMan and Trim. Use FileMan to make copies of the original capture file, then trim each copy using manually specified Start/End positions.
