Why RF View Is Ideal for Field Work
Field RF measurements with portable VNAs (Copper Mountain, Anritsu Site Master, NanoVNA, miniVNA) generate .s2p files on USB drives or via Bluetooth apps. RF View on Android becomes the analysis platform — no laptop required. View S11/VSWR, check filter specs, and compare baseline vs current measurements directly on your phone.
Compatible Portable VNA Sources
| Instrument | Export Format | Transfer Method |
|---|---|---|
| NanoVNA (with app) | .s1p / .s2p | VNA app → Share → RF View |
| miniVNA Tiny | .s2p | BT app → export → RF View |
| Copper Mountain PLANAR | .s2p (Touchstone) | USB → copy to phone → RF View |
| Anritsu Site Master | .s1p | USB drive → Android → RF View |
| Keysight FieldFox | .s2p | USB/WiFi → Android → RF View |
Field Antenna VSWR Verification Workflow
- Measure antenna S11 with portable VNA on site → export .s1p file
- Transfer to Android (BT, USB, or cloud sync)
- Open in RF View → S11 view → check <−10 dB across target band
- Smith chart: is resonance at correct frequency? (Correct for physical installation effects)
- Auto Match: if S11 is worse than expected, design matching network on the spot
- Compare with baseline .s1p from factory or installation day
Cable Fault Location in the Field
Measured S11 with 50m cable shows resonance at 3 MHz:
Fault distance = c / (2 × f_resonance × √εe)
= 3×10⁸ / (2 × 3×10⁶ × √2.3)
= 32.9 meters from measurement point
Load cable .s2p into RF View → Group Delay view:
Delay = τ_group = L / vp = 50 / (0.69 × c) = 241.7 ns
Verify measured group delay matches expected for cable length
