tsapython

An Unofficial Python API for the tinySA Device Series

A non-GUI Python API for the tinySA series of spectrum analyzer devices. This library provides programmatic control over tinySA devices for automated measurements, data collection, and analysis.

This repository uses official resources and documentation but is NOT endorsed by the official tinySA product, owner, or company. Refer to official resources and support for product information. This library was built for the official tinySA device line(s); knock-off or custom devices may not be compatible and have not been tested.

Features

• Device Discovery — automatic detection and serial connection to tinySA devices
• Frequency Sweeps — collect data across specified frequency ranges
• Multiple Modes — support for both input and output modes (device dependent)
• Data Export — easy integration with matplotlib and numpy
• Error Handling — input checking and verbose output options
• Device Control — full programmatic control of tinySA settings and measurements

Installation

pip install tsapython

The library itself depends only on numpy and pyserial. The plotting examples need an optional extra:

pip install "tsapython[plotting]"

Quick Start

from tsapython import tinySA

tsa = tinySA()
found, connected = tsa.autoconnect()
if connected:
    print(tsa.device_id())
    tsa.disconnect()

Examples

The main GitHub repository provides runnable examples, grouped by what they demonstrate.

Getting started / device control

• using_autoconnect.py — detect and connect to a tinySA, read the device ID
• identifying_serial_ports.py — manually identify serial ports (useful if autoconnect has trouble)
• using_command_func.py — send raw device commands for functionality not yet wrapped by the library
• hardware_walkthrough.py — a guided walkthrough of connecting and reading device info/data
• complete_workflow.py — end-to-end: connect, read info, collect a sweep, and plot it

Plotting scan data

• plotting_scan.py — plot a single scan
• plotting_scanraw.py — compare scan vs. the binary scanraw (with decoding to dBm)
• plotting_waterfall_static.py — collect several sweeps and render a static waterfall plot
• plotting_waterfall_realtime.py — a live, continuously updating waterfall plot

Continuous acquisition

• continuous_scanraw_live.py — loop scan_raw and live-plot each frame
• continuous_scanraw_collect.py — loop scan_raw, decode to dBm, and save sweeps to CSV

Analysis

• find_peaks.py — find the strongest signal(s) two ways: the device's marker peak, and a Python multi-peak finder over scan data
• filtering_scan_artifacts.py — show the : firmware artifact and compare a median filter against a moving average on one figure

Exporting data

• save_scan_csv.py — run a scan and write frequency/power pairs to a CSV file

Most plotting examples require the optional plotting dependencies: pip install "tsapython[plotting]"
