What it does
RF Survey Companion extends a tinySA with phone-sized controls, durable survey records, and location-aware views—without pretending a swept analyzer is a real-time I/Q receiver.
Run RF surveys
Collect repeated scalar spectrum sweeps and inspect activity by frequency or over time with clear plots and waterfall history.
Map signal levels
Associate readings with phone GPS locations and review median signal level or above-threshold activity along a route.
Keep your work portable
Save surveys locally, revisit selected sweep points, access supported files on the analyzer SD card, and share or export when you choose.
Field guides
Practical setup and interpretation notes for tinySA measurements with RF Survey Companion.
Run a repeatable tinySA site survey
Choose a capture range and threshold, collect sequential sweeps, and read the activity plots with their limits in mind.
Map signal levels along a route
Set a target frequency, understand GPS-linked and unlocated samples, and inspect the saved map.
Connect a tinySA to Android over USB OTG
Work through device discovery, USB permission, and common connection failures.
A field companion for your spectrum analyzer.
Swipe through real app screens showing the device, survey, mapping, and file-management workflows.
