# SmuView

**A GUI for power supplies, electronic loads and many other measurement instruments - built on top of the [sigrok](https://sigrok.org) signal analysis library.**

## Overview

SmuView is a Qt-based graphical frontend for controlling, visualizing and logging data from lab instruments, like power supplies, electronic loads, multimeters, LCR meters and a wide range of other measurement devices. It can connect and drive multiple devices at once, combines their readings with math channels and automate measurement sequences with a built-in Python scripting engine.

SmuView is part of the [sigrok](https://sigrok.org) project, which builds portable, free and open-source software for interfacing with measurement hardware. It reuses sigrok's device drivers via `libsigrok`, so any instrument supported by sigrok can be used with SmuView.

## Features

- Control multiple devices simultaneously
- Live data acquisition with configurable value panels, plots and data tables
- Math channels to transform or combine signals (e.g. calculating power, resistance or energy from voltage and current)
- Time and X/Y plots with markers, zooming and export to SVG, PDF, or PNG
- Export acquired data to CSV, with various timestamp and formatting options
- Per-device layouts that are saved and restored the next time you connect
- **SmuScript**: a Python scripting interface to automate complex or repetitive measurements and build custom UIs
- Embedded editor for SmuScript
- Sequence output to drive a device setting (e.g. a power supply's output voltage) through sine, triangle, sawtooth or custom waveforms
- Oscilloscopes can be controlled, but no data acquisition yet

See the [user manual](https://knarfs.github.io/doc/smuview/continuous/manual.html) for a complete tour of the available functionality.

## Supported hardware

SmuView supports the sigrok drivers for:

- **Power supplies:** e.g. Rigol DP700/DP800, Korad KAxxxxP, HP 66xx series, Rohde & Schwarz HMC/HMP series and others
- **Electronic loads:** e.g. Arachnid Labs Re:load Pro, ZKETECH EBD-USB+, ITECH IT8500 series
- **Measurement devices:** Multimeters, LCR meters, sound level meters, thermometers, hygrometers, anemometers, light meters, energy meters, tachometers and scales
- **Oscilloscopes:** e.g. Agilent, Hantek, Rigol and others (only support for controlling device, no data acquisition at the moment)

Oscilloscopes, logic analyzers, and mixed-signal devices are not (fully) supported yet (use [PulseView](https://sigrok.org/wiki/PulseView) or [sigrok-cli](https://sigrok.org/wiki/Sigrok-cli) for those); oscilloscope support is on the roadmap.

The full, current device list is in the sigrok wiki: [Supported hardware](https://sigrok.org/wiki/Supported_hardware) and the [SmuView wiki page](https://sigrok.org/wiki/SmuView#Supported_devices).

> [!NOTE]
> If a controllable device connects and acquires data but misbehaves as soon as you change a setting (e.g. output voltage), its `libsigrok` driver is likely missing a required mutex. Please report this on GitHub.

## Installation

Pre-built packages are available for Linux, Windows, and macOS. The **continuous release** has the latest development snapshot and is the recommended download. A tagged **stable release** is also available.

- **Linux (amd64 / arm64):** AppImage, no installation required:
  ```bash
  chmod u+x SmuView-x86_64.AppImage
  ./SmuView-x86_64.AppImage
  ```
- **Windows (64-bit):** Self-contained installer (Windows 8 or later)
- **macOS (arm64):** DMG image (macOS 15 or later)

### Building from source

SmuView depends on `libsigrok` and a Qt-based toolchain. Detailed, platform-specific build instructions are available on the sigrok wiki:

- [Building SmuView](https://sigrok.org/wiki/Building#SmuView)
- [Linux build notes](https://sigrok.org/wiki/Linux#SmuView)

or in the manual:

- [Manual - Installation](https://knarfs.github.io/doc/smuview/continuous/manual.html#installation)

```bash
git clone https://github.com/knarfS/smuview.git
cd smuview
mkdir build && cd build
cmake ..
make
```

## Documentation

- [User manual (HTML)](https://knarfs.github.io/doc/smuview/continuous/manual.html) / [PDF](https://knarfs.github.io/doc/smuview/continuous/manual.pdf)
- [SmuScript Python bindings API](https://knarfs.github.io/doc/smuview/continuous/python_bindings_api.html)
- [SmuView wiki page](https://sigrok.org/wiki/SmuView) on sigrok.org

### A short SmuScript example

```python
import smuview
import time

# Connect a device.
dmm_dev = Session.connect_device("hp-3478a:conn=libgpib/hp3478a")[0]
time.sleep(1)  # give the device time to create its signals

# Read the last sample from channel P1.
sample = dmm_dev.channels()["P1"].actual_signal().get_last_sample(True)
print(sample)

# Open the default tab for the device in the UI.
UiProxy.add_device_tab(dmm_dev)
```

More examples are available in the [`smuscript/`](smuscript/) folder of the repository.

## About sigrok

[sigrok](https://sigrok.org) is a portable, cross-platform, free and open-source signal analysis software suite covering logic analyzers, oscilloscopes, multimeters and many other device classes. SmuView is one of several sigrok-based frontends, alongside [PulseView](https://sigrok.org/wiki/PulseView) for logic analyzers and scopes, as well as [sigrok-cli](https://sigrok.org/wiki/Sigrok-cli) for the command line.

## Getting help

- **Issues / feature requests:** [GitHub Issues](https://github.com/knarfS/smuview/issues)
- **Mailing list:** [sigrok-devel](https://lists.sourceforge.net/lists/listinfo/sigrok-devel)
- **IRC:** `#sigrok` on [Libera.Chat](https://libera.chat/)

## Contributing

Pull requests are welcome. If you'd like to add support for a new instrument, note that device drivers live in `libsigrok`, not in SmuView itself - see the sigrok [driver development](https://sigrok.org/wiki/Developers) resources to get started, then open an issue here to hook it up in the UI.

## Project status

SmuView is under active development. Current roadmap items include oscilloscope support and import/export of user-device layouts - see the [wiki roadmap](https://sigrok.org/wiki/SmuView#Roadmap) for details.
