Use Cases for Multi-File Comparison
- Vendor selection: Compare 4 filter suppliers' S21/S11 on same chart
- Lot consistency: 10 samples from same supplier → check for outliers
- Temperature drift: −40°C, 25°C, 85°C measurements overlaid
- Sim vs measured: Simulation .s2p alongside measured .s2p
- Before/after matching: Raw DUT and matched circuit S11 comparison
Loading Multiple Files in RF View
- Open RF View → S-Parameter Plot tab
- Tap folder icon → select first .s2p file → load
- Tap "+" (Add) icon → select second file → load
- Repeat: up to 8 files load simultaneously
- Each file gets auto-assigned a unique color
- Filename legend appears in the plot area
Table Marker for Side-by-Side Comparison
Activate Table Marker mode: Marker bubble shows ALL loaded files' values at marker frequency Example with 4 vendor files loaded: At 1815 MHz marker: VendorA.s2p: S21 = −1.82 dB VendorB.s2p: S21 = −2.15 dB VendorC.s2p: S21 = −1.96 dB VendorD.s2p: S21 = −3.12 dB (FAILS spec) Move marker to rejection frequency (1750 MHz): VendorA: S21 = −52.1 dB ✓ VendorB: S21 = −48.3 dB ✗ (spec: >50 dB) VendorC: S21 = −55.4 dB ✓ VendorD: S21 = N/A (failed passband)
BW Marker Comparison
BW Marker reads bandwidth from the CURRENTLY SELECTED trace (highlighted). Switch between traces by tapping the legend to select each file:
- Tap VendorA trace in legend → BW Marker reads A's bandwidth
- Tap VendorB trace → BW Marker updates to B's bandwidth
- Record both values → compare: VendorA BW=40.5 MHz vs VendorB BW=38.9 MHz
RF View Multi-File: Up to 8 simultaneous files with color coding. Table Marker reads all simultaneously. BW Marker shows per-trace bandwidth. Delta Marker compares two specific traces. Free on Android.
