ScanBridge
Turn Shure Wireless Workbench .sdb3 scans into CSV, and CSV scans from any analyzer back into .sdb3. Everything runs on this page: your files are never uploaded.
.sdb3 → CSV
By default the CSV matches what Wireless Workbench exports: peak hold, the higher of the antennas at each frequency, in kHz. You can also export one antenna, a single sweep, or MHz.
CSV → .sdb3
Takes frequency,level rows in Hz, kHz or MHz (the unit is detected), with commas, semicolons or tabs, and header rows are fine. The data is laid on an even frequency grid, and any gaps are marked "no data", not filled in.
What's kept
A CSV has one trace. A .sdb3 made from it holds that trace as one sweep plus its peak hold. You can lay it out as a single trace or as Antenna A and B. The other details (antennas, sweeps, scanner) only exist in the original .sdb3.
