v3.0.1

Bugfixes for Version 3.0

• Triggering for NI cDAQ devices was not set up correctly. It is now fixed.
• When performing testing without shakers (e.g. modal hammer testing), the 3.0 version of the software had a bug that would prevent the measurement from starting. This has been fixed so that shaker-less tests can be run.
• When running NI hardware, it now prints the actual sample rate achieved to the Python terminal window. Some NI hardware has discrete sample rates, but instead of giving an error when an invalid sample rate is selected, it simply selects the closest one. Now you can see what sample rate the hardware is actually using, which will hopefully prevent users from acquiring data at a different sample rate than they expect.

v3.0.0

Rattlesnake Version 3.0 with Overhauled System Identification

Run Rattlesnake by downloading the source code and running as a Python script.

Changes:

• Significant code refactor and UI overhaul to improve system identification phase of the control.
• Addition of modal testing environment.
• Added Data Physics Quattro device
• Added warning and abort limits

Known Issues:

• Intermittent plotting issues with high-dpi settings on Windows. Whenever possible, keep DPI scaling at 100%
• LAN-XI errors due to bad ICP or overranges are not currently handled well.
• LAN-XI sometimes requires a hard reboot in between tests, mostly for large channel count tests.
• Errors from NI hardware (underrun, etc.) are not currently handled well and will generally crash the software.
• Test profile data is not currently stored to the output NetCDF4 file.

Version 2.0: Combined Environments

Rattlesnake Version 2.0 containing Combined Environments Functionality

Run Rattlesnake by downloading the source code and running as a Python script, or downloading the Windows executable and running like any other program.

Changes:

• Significant UI overhaul to facilitate combined environments control.
• Ability to select environments or run a combined environments test.
• Ability to run on multiple hardware devices or synthetic control
• Ability to load test from a spreadsheet containing combined environments information.

Known Issues:

• Intermittent plotting issues with high-dpi settings on Windows. Whenever possible, keep DPI scaling at 100%
• Some issues with going backwards in the program flow when using Transformation Matrices. Whenever possible restart Rattlesnake when going back to change previously initialized parameters.
• LAN-XI errors due to bad ICP or overranges are not currently handled well.
• LAN-XI sometimes requires a hard reboot in between tests, mostly for large channel count tests.
• Errors from NI hardware (underrun, etc.) are not currently handled well and will generally crash the software.
• Test profile data is not currently stored to the output NetCDF4 file.
• Test level doesn't change in system identification for the transient environment
