Following questions from some SoundCheck users who had watched #3 in this series (sequence optimization), Steve Tatarunis takes a look at the measurement confidence function in SoundCheck, and explains the trade-offs between speed and accuracy when choosing a step size to optimize your measurement.
Anastassia Tolpygo demonstrates some neat features of virtual instruments that you may not have seen before. These enable you to make a quick distortion measurements, accurately measure frequencies at very high resolution, and plot and save curves over time using just the virtual instruments without the need for a sequence step.
The ability to quickly generate test sequences is one of the most powerful SoundCheck skills you can acquire. We are bringing a 2 hour basic sequence writing course to the comfort of your own home with our new online training.
This 2 hour course is a condensed version of the basics of sequence writing from our popular 2 day training class. We will start from the beginning, explaining how to determine the test parameters and hardware that will meet your specific test requirements. We will look at best practices for creating a sequence, and finally we will assemble a sequence from scratch. This course is ideal for novice SoundCheck users, or those who have been using SoundCheck with sequences that others have written and who are ready to start developing their own. This training is free to support contract holders and $79 for others.
In this short video, Steve Tatarunis takes a deeper dive into the Offline Statistics functionality in SoundCheck, demonstrating how you can run statistical analyses from home on data from your production facility or overseas contract manufacturer. No hardware required – just your computer with SoundCheck and some measured data!
While you are working from home, optimize your SoundCheck sequences by tweaking your limits for optimum quality and yield. Devin Vaillancourt explains the different types of limits available (absolute, floating, aligned, and more), and once you have explored the different types, you can test out different limit configurations using saved data from products that you have already measured.
Learn how to level-up your SoundCheck sequence using Custom Steps – LabVIEW VIs that can be used as steps in SoundCheck sequences to implement operations that cannot be done natively in SoundCheck. A selection of custom step templates built into SoundCheck accelerates the development of custom steps with examples that allow you to open and close virtual instruments, control turntables, read/write serial numbers and even open any .exe file such as a Python script. Devin Vaillancourt demonstrates how to use this powerful feature.
There are many times when it is desirable to display multiple data sets on one graph – for example, testing multichannel devices, comparing devices, comparing measurements to the fundamental, comparing EQ curves, etc. In this short video, Steve Tatarunis demonstrates how to display multiple curves on one graph, both by simply dragging and dropping and also automatically via a sequence.
In this short video, Cam Ruffle-Deignan walks you through how to predict listener preference based on the Harman Target Curve. This free sequence (which can be downloaded here) can recall previously saved data as well as capture new data, making this a great ‘work from home’ project if you have previously saved measurement data on your headphones.
Cam Ruffle-Deignan demonstrates batch processing and analysis – powerful tools that enable groups of waveforms (or other forms of data) to be processed with just one step, either in a sequence or offline.This simplifies the processing of large volumes of data in offline mode, and is useful in multi-channel test system sequences.
