tsactl is a command line tool for controlling and interacting with the tinySA spectrum analyzer via its USB serial interface. It allows you to:
- Configure sweep parameters (frequency range, center, span, ...)
- Configure markers and traces
- Save screenshots in PNG format
- Save trace data to CSV (single/multiple traces)
- Trigger menu options (e.g. to enable waterfall view)
- Reset device (DFU mode for basic model)
- Load/save presets
- Execute raw commands (for when the command is not yet implemented by
tsactl) - And more - see the command overview for details
It automatically detects connected tinySA devices and identifies the model (basic or ultra).
All platforms supported by the go.bug.st/serial module should be working: Linux, Windows, macOS.
Note: Tested on Linux, Windows and Raspberry Pi with a tinySA Ultra (firmware tinySA4_v1.4-197-gaa78ccc). If you experience problems with your device, please report a bug.
You can download the latest tsactl binary for your platform from the release page and place it in a directory that's in your PATH.
If no serial port is defined, the tool will iterate over all serial ports and checks if a device responds by issuing the version command.
Based on the version response, the model (basic or ultra) is identified (here tinySA4, meaning ultra):

Frequency arguments can be specified using notations like 1.5Ghz, 1.5g, 250k, 250khz, or in scientific notation such as 1.23e6.
Most flags support relative arguments, e.g. to move the sweep center frequency by 2mhz, you can use --center +2mhz.
Time arguments can be written as 1.2s, 950ms, 750m, 1200us or 950u.
# Sweep between 410.5mhz and 600mhz
$ tsactl sweep --start 410.5mhz --stop 600mhz
# Check current sweep settings
$ tsactl sweep
Status: resumed
Frequency: 410.5 MHz to 600 MHz (450 points)
Center: 505.25 MHz
Span: 189.5 MHz
# Increase/decrease frequency by using relative arguments
$ tsactl sweep --center +2mhz
# Change sweep span
$ tsactl sweep --span 20mhz# Enable second trace and activate max hold
$ tsactl trace 2 --calc maxh
# Enable second marker, assign to trace 2, move to peak frequency and disable delta mode
$ tsactl marker 2 --trace 2 --peak --delta=off# Set marker 2 to frequency 419mhz
$ tsactl marker 2 --freq 419mhz
# Assign marker 2 to trace 2
$ tsactl marker 2 --trace 2
# Enable/disable marker tracking
$ tsactl marker 2 --track
$ tsactl marker 2 --no-track
# Show details about active markers
$ tsactl marker
Active markers:
Marker 1: 419 MHz -89.4 (Index 45)
Marker 2: 495.32 MHz -67.9 (Index 214)# Save current screen as PNG

$ tsactl raw sd_list

SA_250403_191532.csv 8612

# Binary output is supported
$ tsactl raw scanraw 100mhz 120mhz 450 > scanresult.binIf you are familiar with the tinySA serial commands and don't want to use those from tsactl, you can use a simple alias to the raw command:
$ alias tinysa='tsactl raw $@'
$ tinysa sd_list
$ tinysa load 0
$ tinysa sweep 120M 150M
$ tinysa capture > capture.binIf you experience issues with your tinySA model or firmware version, please run tsactl in debug mode:
tsactl <command that makes problems> --flags-that-makes-problems --debugWhen reporting the issue on GitHub, include the debug output if possible - it helps track down the problem. Thanks!
