File Won't Open? Troubleshooting
Issue: "Cannot open" or blank plot Fix 1: Check file extension — must be .s1p, .s2p, .s3p, or .s4p Fix 2: Check options line in file — must start with # (e.g., # GHz S DB R 50) Fix 3: Try Batch Converter → Format Detect → converts auto-detected format Fix 4: Very large files (>500k points): split with frequency crop first
