Software Update: WaveForms 3.5.4


WaveForms 2015 is the user interface that controls the Analog Discovery 2 and Electronics Explorer Board, and gives access to all of their benchtop functionality. We have just posted a new version of WaveForms 2015, version 3.5.4 available for download on the wiki. WaveForms 2015 3.5.4 left the overall look and existing functionality of the Analog Discovery 2 alone, but has added some very useful options, and made user experience improvements.

The Oscilloscope has a new Spectogram view. The Spectrogram is a visual representation of the spectrum of frequencies in a sound or other signal as they vary with time. The horizontal axis represents time, the vertical axis is frequency; a third dimension indicating the amplitude of a particular frequency at a particular time is represented by the intensity or color of each point in the image.

Separate acquisitions now keep their own time positions and span. In both the Logic Analyzer and Oscilloscope tool, you can open multiple acquisitions in separate windows. This allows you to keep a previous acquisition up in case you need to compare or review it later. Previously the time position and span options controlled all tabs, but now each tab remembers it’s own time position and span options.

The Oscilloscope window with multiple tabs open. Each tab will remember its own time scale settings.

Logic Analyzer triggering is simplified. In previous versions if you wanted to do advanced triggering the custom trigger menu gave the ability to control custom triggering, however, this was a overly complicated interface. In this version, that interface was removed and the Simple, Pulse, and Protocol interfaces replace the functionality.

 Custom text can be added to an exported picture. In previous versions when images were exported a time and date stamp, as well as device stamp were added to the image. Now in addition to the automatic text you can add custom text. So if you want to label a specific acquisition with details about the circuit or behavior you’re observing you can.

When you open the device manager to select your device you may notice an addition. The Digital Discovery, which is coming very soon. If you’d like to preview the features of the Digital Discovery you can use DD demo mode in WaveForms 2015, or check out it’s resource center. You’ll find a getting started guide, and a walk-around for each tool.

About Author

When I started school I wasn’t interested in any of things I’m passionate about now. In fact originally I started out wanting to study art. But then I decided I didn’t want to have people telling me what to create, so I changed to music. Then I decided I didn’t want to ruin a hobby by making it my career. At the same time my Physics class was teaching a unit on the physics of music, and I thought that was way interesting, so I changed to physics. Then by the time physics was over I decided that the coolest part of physics was electricity and magnetism, and I may as well get a degree that transfers directly into a career. So while all this was happening, I was attending Shoreline Community College, and during that time I found my passion, or rather presented itself repeatedly, until I realized, maybe I should take a hint from the universe. While at community college, I was asked to help at the high school by tutoring chemistry students. Then I was asked to help at the elementary school by being a math Olympiad coach. I continued both because I found I really enjoyed it. I also had an opportunity, and was hired to be a tutor in the Math Learning Center at the Community College, a job I really loved. At the same time I was working as a Nanny, which I had been doing for several years, the main reason because I could and would answer the hard questions the kids asked honestly (i.e. why is the sky blue). I then was recommended by the patrons of the MLC to the transfer tutoring center (private tutoring,) and developed a wait list of students. Through all these opportunities at some point I realized that I loved watching people go from totally lost, to masters of a subject. I was also forced to admit that having all these opportunities continually renewed, I must have been somewhat good at it. So I decided I wanted to teach, which fits with my mission oriented personality. I saw a serious lack of passionate ECE professors in the institutions I attended. At WSU I continued this trend by being ask to TA for computer science and electrical engineering, being a TA for a total of 4 semesters. This continued by getting an amazing opportunity in my first semester at Washington State University to work at Digilent, an educational company. So even if I didn’t want to teach, turns out I can’t avoid it. Luckily it is my main passion.
