SmuView (sometimes abbreviated as "SV") is a Qt based GUI for power supplies, electronic loads and all sorts of measurement devices like multimeters, LCR meters, scales and so on.
It is licensed under the terms of the GNU GPL, version 3 or later.
- Remote control devices.
- Data acquisition.
- Connect and use multiple devices at the same time.
- Math channels to combine signals or manipulate signals.
- Data export as a CSV file.
- Python interface to script complex measurements with multiple devices.
- Change device settings (e.g. voltage output of a psu) periodically with a sequence table.
Please refer to the SmuView manual for a lot more information.
It is known that for controllable devices (like power supplies) a mutex has to be added in the corresponding libsigrok driver. If that mutex has not been added, you will notice the following behavior:
- The device connects without problems and starts to acquire data.
- When you change any property of the device (e.g. the set voltage of a power supply), SmuView crashes or some other strange behavior occurs.
These power supplies should work:
- Conrad DIGI 35 CPU
- Korad KAxxxxP series
- RDTech DPS series
- All power supplies that use the scpi-pps driver
All other power supplies probably don't work. Please get in touch via github to add support.
These electronic loads should work:
All other loads probably don't work. Please get in touch via github to add support.
The following measurement device types should be supported:
- LCR meters
- Sound level meters
- Light meters
- Energy meters
This devices aren't supported yet, but maybe will be in the future:
SmuView has a python scripting extension to automate, setup and control complex or repetitive measurements, to process the incoming data and to create a standardized user interface for those measurements.
The API documentation can be found here.
The following short example connects the HP 3378A DMM via GPIB, reads a sample and creates the default tab for the device:
import smuview import time # Connect device. dmm_dev = Session.connect_device("hp-3478a:conn=libgpib/hp3478a") # Sleep 1s to give the devices the chance to create signals time.sleep(1) # Get last sample from channel P1 sample = dmm_dev.channels()["P1"].actual_signal().get_last_sample(True) print(sample) # Add default tab for the DMM device. UiProxy.add_device_tab(dmm_dev)
Binaries and source code tarballs are available here.

PKG_CONFIG_PATH=/<prefix-of-libsigrok-installation>/lib/pkgconfig/if libsigrok is installed to a non-standard prefix. See also Building#Installing_to_a_non-standard_directory_using_LD_LIBRARY_PATH for more details.
- To change the install prefix:
cmake -DCMAKE_INSTALL_PREFIX=<prefix-dir>/ ..
- To show compiler arguments during the build:
- To make a non-stripped debug build
cmake -DCMAKE_BUILD_TYPE=Debug ..
- To disable -Werror:
cmake -DDISABLE_WERROR=y ..
- To build with clang:
CXX=clang++ cmake ..
- Programmability via a flow diagram to do complex measurements.
- Support oscilloscopes.
