tinySA tinySA ZS304 software
Remote control and data logging for the tinySA tinySA ZS304 spectrum analyzer, on Windows, Linux and macOS - with the same panel BenchMesh uses for every spectrum analyzer.
Status
Very likely. Support for the tinySA tinySA ZS304 was written from tinySA’s programming manual and follows the same engine as the bench-tested instruments, but nobody has confirmed it on a real tinySA ZS304 yet. If you own one, connecting it once and reporting the result moves it to Community-confirmed.

Connect it, press Detect, try the controls - then tell us how it went. Every confirmation moves a model from “Awaiting” to “Community-confirmed” for everyone.
Questions
- Does BenchMesh work with the tinySA tinySA ZS304?
- Very likely. Support for the tinySA tinySA ZS304 was written from tinySA’s programming manual and follows the same engine as the bench-tested instruments, but nobody has confirmed it on a real tinySA ZS304 yet. If you own one, connecting it once and reporting the result moves it to Community-confirmed.
- How do I connect the tinySA ZS304 to my PC?
- Over USB-serial / RS-232. 115200 baud, 8N1. Plug in the USB cable (or a USB-RS-232 adapter); BenchMesh finds the port. Then press Detect in BenchMesh: it identifies the spectrum analyzer by its reply and adds it to the bench.
- What can I control on the tinySA ZS304?
- Spectrum analyzer: set attenuation, center, marker, marker freq, peak search, rbw, ref level, scale; read atten, center, marker, marker freq, marker level, points, rbw, ref level.
- Can I log tinySA ZS304 measurements to CSV?
- Yes. Right-click any reading to add it to a recording; every instrument on the bench is sampled on one shared timeline and exported as one CSV.
- Is BenchMesh free?
- Yes. BenchMesh is free and open source, for Windows, Linux and macOS, and works offline.
