Purpose-built
Industrial utility without unnecessary complexity
SignalBench is designed around the work technicians and engineers perform at a machine, workbench, control panel, or commissioning site.
HMI
Frameless interface
A professional HMI-style layout provides readable values, clear states, and practical operation on industrial displays.
LOC
Local and private
The application runs offline. It requires no account, contains no advertising, and does not transmit calculation or equipment information.
Installation
Run SignalBench in three steps
AppImage keeps the application portable and avoids system-wide installation.
Download the AppImage

File integrity
Verify the downloaded application
NorthRivet publishes a SHA-256 checksum so the downloaded file can be compared with the original release artifact.
sha256sum -c NorthRivet-SignalBench-0.1.0-beta-x86_64.AppImage.sha256

Privacy and trust
Your calculations remain on your computer.
SignalBench is designed for offline industrial use. It does not require a user account, send telemetry, display advertising, or upload calculation history.
No account
Download and run the application without registration or login.
No telemetry
Application-controlled calculation and equipment data are not transmitted.
Local history
Saved calculations remain in the user’s standard local application-data directory.
Release information
0.1.0-beta beta
