Saleae Logic 2

Saleae Logic 2

Use this when hardware traces need to become something analyzable instead of just pretty waveforms.

When to use Saleae Logic 2

Use Saleae Logic 2 when you need to:

• open .sal captures and inspect digital or analog traces
• export raw signal data to CSV or binary
• export analyzer tables such as UART, I2C, SPI, CAN, or protocol decodes
• automate record, load, analyze, save, or export workflows from Python

Manual Export Workflow

Data table export

In Logic 2, use the three-dot menu next to Data and choose Export Table.

Raw data export

Use Options in the lower-right corner, then Export Raw Data. Choose channels, time range, format, and destination.

Analyzer export

Use the three-dot menu next to a specific analyzer and choose Export to TXT/CSV.

Automation API Workflow

from saleae import automation

with automation.Manager.connect() as manager:
    capture = manager.load_capture("trace.sal")
    capture.export_raw_data_csv("export_dir")
    capture.close()

Key automation capabilities include:

• Manager.connect() or Manager.launch()
• load_capture() for existing .sal files
• export_raw_data_csv() and export_data_table()
• save_capture() for .sal output

Practical Notes

• Official docs note that raw digital CSV only records transitions plus a final trailing sample marker.
• Some analyzers cannot use native per-analyzer export in Logic 2; exporting through the data table is the supported fallback.
• The automation API is ideal when the end goal is CSV, scripting, or batch protocol parsing.

Caveats

• The automation API expects a running local Logic 2 instance unless you launch it programmatically.
• Exported CSV is not identical to every original waveform detail unless you choose the right channels and ranges.
• Some workflows still require manual analyzer setup before export choices become meaningful.
