View, plot and edit s-parameter data with support for arbitrary N-port networks. Smith chart and rectangular views, S/Y/Z matrix conversion, and high-quality PDF vector export.
FIGURE 1 — LOAD STABILITY CIRCLES & GAIN/PHASE vs FREQUENCY
Full support for .s1p, .s2p, .s3p … .snp files. No limit on port count — analyze any multi-port network.
Convert between S-parameters, admittance (Y) and impedance (Z) matrices with mA, ri, or dB formatting.
Interpolate s-parameter data to any frequency grid. Useful for combining datasets measured at different frequency points.
Industry-standard Smith chart display with constant resistance and reactance circles. Visualize impedance across the full bandwidth.
Magnitude and phase vs. frequency in rectangular format. Dual y-axis display for simultaneous mag and phase.
Automatically arranges all S-parameter plots in a grid. Display properties and configuration saved within file comments for repeatability.
Read s-parameter files directly from .zip archives — no extraction required. Streamlines batch file management.
Export any plot as publication-quality vector graphics to PDF. Scales cleanly to any resolution for reports and presentations.
Plot display properties and layout configuration are saved within file comments, ensuring reproducible views every time you open a file.
