A cross-platform Python desktop application that connects to NanoVNA vector network analyzers (and TinySA) to read, display, and analyze sweep data. It supports multi-segment sweeps, Smith/LogMag/Phase/VSWR charts, calibration, TDR cable measurement, filter analysis, and Touchstone file import/export.

Use cases

• save sweep data from my NanoVNA to Touchstone files
• display Smith chart plots from a vector network analyzer on my PC
• sweep a wide frequency range in segments for more than 101 points
• measure cable length with TDR using a NanoVNA
• analyze antenna SWR and impedance across amateur radio bands
• analyze filter response from S11 and S21 measurements
• average NanoVNA readings for cleaner high-frequency data

When to choose

• you own a NanoVNA, NanoVNA-H/H4/F, LiteVNA, AVNA, or TinySA and want PC-based control and visualization
• you need higher-resolution sweeps than the device's onboard display allows
• you want to export measurements as Touchstone files for other RF tools
• you need in-application calibration and reference trace comparison

When to avoid

• you need a standalone analyzer without a computer connection
• you require a supported open-source license for redistribution (the repo shows no license)
• you work with VNAs from other vendors not in the supported device list
