1: Workspaces
The different component windows are arranged freely in the MDI (Multiple Document Interface) area of the workspace. Any number of workspaces can be added that will stack upon each other by default and can be put forward using the side tabs (1). The workspace index appears on the left of the workspace top bar (2):
The different component windows are:
- Device to interface and control a physical SDR hardware device connected to the system
- Main Spectrum to show the spectrum of the baseband related to the device
- Channel to control a channel plugin
- Feature to control a feature plugin
The workspaces are attached to a docking area of the main window and can be undocked to be moved to another display in a multiple screen setup for example.
The workspace has a top bar with the following controls:
1.1: Workspace index
Shows the index of the workspaces in the list of workspaces as a "W" followed by the index.
1.2: Create new receiver
Creates a new receiver (source device set). A dialog opens to select which receiving device to use:

1.9: Stack windows
Arranges windows in the MDO area of the workspace in a way similar to the arrangement in version 6:
- Devices are stacked in numerical order top left.
- Fixed height features are stacked in order underneath devices and resized to match width of devices
- Channels are stacked in device then channel index order down the right and resized horizontally to match and then any available vertical space is shared being vertically expanding channels
- Remaining space in the middle is shared between spectrums and expanding features
1.10: Auto stack windows
Applies the stacked arrangement above automatically when elements are added.
1.11: Dock/undock workspace

2.2: FFT
When clicking on the FFT submenu a dialog opens for running the fftwf-wisdom
utility with a choice of direct and possibly reverse FFT sizes. It produces a so called wisdom file fftw-wisdom
that speeds up FFT allocations. It is created at a default location and will be used at next invocations of SDRangel.
2.2.1: FFTW Wisdom program
Path to the fftwf-wisdom
program. It looks in the PATH
variable and the "current" directory (that is the same directory where the sdrangel
binary resides).
2.2.2: Select FFTW Wisdom program
Opens a file selection dialog to look for the fftwf-wisdom
program.
2.2.3: FFT maximum size
Select the maximum FFT size for precomputation. Sizes are powers of two between 128 and 32k.
2.2.4: Reverse FFT
Select this checkbox to cover reverse FFTs
2.2.5: Command line
This is the command line that will invoke the fftwf-wisdom
program with its options
2.2.6: OK: launch the FFTW wisdom program
When clicking the "OK" button the fftwf-wisdom
program is launched in the background. A message pop-up appears with the PID of the process and the dialog exits. A new pop-up will appear with the output content when the program completes.
2.2.7: Cancel: dismiss the dialog without execution
When clicking the "Cancel" button the dialog is dismissed without execution of the fftwf-wisdom
program.
2.3: Commands
This is a tree view of the saved commands. Commands describe the path to an executable file, its arguments a possible link to a keystroke event that triggers the execution. Similarly to presets commands can be arranged into groups and have a description short text.
Typically an "executable file" is a script (Python, shell, whatever...) or can be a compiled program (c, c++, java, whatever...) that interacts with SDRangel using its web REST API. When called from within SDRangel they can act as "macros" allowing to perform actions automatically.
Of course any binary that resides in your system can be used that way like /bin/ls
or /bin/date
although these two are of anecdotal interest...
2.3.1: Command selection
You select a command or a command group by clicking on its line in the tree view. All actions (6) will be done relative to this command or command group.
2.3.2: Group
You can organize your commands into groups. Groups can be collapsed or expanded by using the caret icon on the left.
2.3.3: Description
Short description of a command.
2.3.4: Key binding indicator
-
: no key bindingP
: key press bindingR
: key release binding
2.3.5: Key binding sequence
This is a descriptive text of the key sequence that is used for the key binding.
2.3.6: Command control or actions
The controls are located as icons at the bottom of the window:
2.3.6.1: Create new command
Click on this icon to create a new command. This opens an edit dialog see the edit section (5B.6.3) for the details of the edit dialog.
2.3.6.2: Duplicate command

You can select an existing group with the combo or create a new one for this command using the text edit box
2.3.6.3.2: Edit description
You can edit the description using this text box. The description will appear in the tree view.
2.3.6.3.3: Executable file selection
Clicking on this button will open a file dialog to select the executable file that will be run with this command. The file selection dialog has predefined file pattern selections:
*
for All files*.py
for Python files*.sh
or*.bat
for shell or batch files*.bin
or*.exe
for binary files
2.3.6.3.4: Executable file path
This is the full path of the selected executable file.
2.3.6.3.5: Command line arguments
Use the text box to edit the arguments given to the executable file as in program arguments
.
You can use special codes to insert information specific to the application context:
%1
: the address of the web REST API%2
: the port of the web REST API%3
: the currently selected device set index
2.3.6.3.6: Key binding
Use this checkbox to enable or disable the command execution binding to a key or combination of keys press or release event
2.3.6.3.7: Key binding capture
Use this button to capture the key or key combination that will be used for the key binding. After pushing this button just type in the key or key combination.
2.3.6.3.8: Key binding display
This shows the key or combination of keys used for the key binding.
2.3.6.3.9: Release key binding
Use this checkbox to bind the key or combination of keys to the key release event. If unchecked the binding will be associated to the key press event.
2.3.6.3.10: Confirm changes
Use the "OK" button to confirm the changes.
2.3.6.3.11: Cancel changes
Use the "Cancel" button to cancel the changes.
2.3.6.4: Run command or groups of commands
This will run the currently selected command. If the selection is a group it will run all commands of the group starting them in the displayed order. Please note that commands are run in independent processes and therefore all launched commands in the group will run concurrently.
2.3.6.5: View last command run details
This dialog will show the results of the last run including the output (merged stdout and stderr).
2.3.6.5.1: Process status
When the process is not running the stop icon (■) is displayed. The background color indicate different states:
- no color (same as background): the process has never run during this session
- red: the process ended with error
- green: the process ended successfully. This does not mean that there was no programmatic error.
When the process is running the play icon (▶) is displayed with an orange background.
2.3.6.5.2: Refresh data
Pushing this button will update the data displayed with the latest status. Please note that the log is displayed only when the process is terminated.
2.3.6.5.3: Start time
This is the timestamp of process start. It is filled with dots ...
if the process has never started during this session.
2.3.6.5.4: End time
This is the timestamp of process end. It is filled with dots ...
if the process has never terminated during this session.
2.3.6.5.3: PID
This is the process PID. It is 0 if the process has never run during this session.
2.3.6.5.6: Process kill
Use this button to kill (send SIGKILL) the running process. It has no effect if the process is not running.
2.3.6.5.7: Command line
This shows the actual command line that was used to start the process
2.3.6.5.8: Error status
This is the translation of QProcess::ProcessError
. Possible values are:
...
: the process has never run during this sessionFailed to start
: the process could not start. For example the executable file has no execution rights actuallyCrashed
: the process ended with crash. This is the status when you killed the processTimed out
: the last waitFor...() function timed out.Write error
: an error occurred when attempting to write to the process. For example, the process may not be running, or it may have closed its input channel.Read error
: an error occurred when attempting to read from the process. For example, the process may not be running.Unknown error
: an unknown error occurred.
2.3.6.5.9: Exit code
This is the program exit code. When the process crashes this is the signal by which the process end was caused. For example if you kill the process with button (6) it sends the process a SIGKILL (code 9) and therefore the value is 9.
2.3.6.5.10: Exit status
There are only two possibilities: either the program exits normally but possibly with a non zero exit code or it ends with a crash.
2.3.6.5.11: Process log
This is the log of the process (merged stdout and stderr). Please note that it is updated only on program termination.
2.3.6.5.12: Exit
By pushing the "Close" button the process output window is closed.
2.3.6.6: Save commands
This will save the commands immediately. The commands will be automatically saved when the application exits normally.
2.3.6.7: Delete commands or group of commands
This will delete the currently selected command or if selection is a group this will delete all commands in the group.
2.3.6.8: Activate keyboard bindings
Use this button to activate the keyboard bindings. Note that you need to have this button selected (its background should be lit in beige/orange) for the key bindings to be effective.
2.4: Graphics
When clicking on the Graphics submenu a dialog opens for setting graphics options.
2.4.1
Multisampling (MSAA) determines whether multisampling anti-aliasing is used to removed the jagged edges of lines when rendering 2D and 3D spectra. The higher the number of samples chosen, the better quality the anti-aliasing will be, but higher values require more GPU processing and memory.
Changing this option will only take effect when spectrum windows are recreated (not just hidden then made visible again), so in some cases it may be necessary to restart SDRangel to see the difference.
