Versions:
tinySA-App is the official Windows companion program for the tinySA family of pocket-sized spectrum analyzers, streamlining the capture, visualization, and storage of RF measurements from 100 kHz up to 960 MHz. Built by the same engineering team that produces the tinySA hardware, the application duplicates the instrument’s on-screen trace on a larger desktop display, adds mouse-driven markers, and allows unlimited reference traces to be saved for later comparison. Engineers testing antennas in the field can log sweeps to CSV for post-processing in spreadsheet or MATLAB environments, while radio amateurs aligning repeaters benefit from the real-time peak-hold function that reveals intermittent carriers. Classroom instructors connect multiple analyzers to a single laptop via separate USB cables and cycle through each port to demonstrate filter responses across student groups. The program also exposes a remote-command interface, so automated test scripts can set start/stop frequencies, resolution bandwidth, and attenuation without touching the front panel. Version 1.1.20.1, the first public release, ships with signed drivers for Windows 10 and 11, detects the tinySA automatically when plugged in, and exports screenshots as PNG or PDF for documentation. Because the installer bundles the necessary SEGGER J-Link libraries, no additional SDK downloads are required, and a lightweight 32-bit build remains available for older notebooks used in remote site surveys. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
