  1. Hi, for the captures below, first channel 1 and then channel 2 see a 1Vpp (500 mV amplitude) sine wave at 5.501 kHz... the Ch1 FFT looks right, but maybe the vertical scale on Ch2 is not accurate... it is labeled "Ch1" and the range is -1000mV to +1000mV, peak location not plotted at 500mV for Ch2... but in both cases the little tag reads the appropriate amplitude... for a while this has confused me as to what normalization the FFT used... pretty sure it is amplitude, not pp or RMS... but perhaps the display for Ch2 needs some analysis... best, Harry Nelson
  2. Hi, I don't see the "Bode plot" tool up in the upper right corner of the display window... seems to be 6, vertically... (1) FFT (2) expand to full time base (3)recenter time base (4)download (5)Pinout (6)full reset Firmware version is 1.301.0, says that is latest in configuration, macOS High Sierra, 10.13.6. thanks, Harry
  3. Greetings... Waveforms Live and OpenScopeMZ have generally worked very well for me. One small problem is the RMS calculation in the Math Menu. It seems not to subtract off the mean value... seems to be sqrt((1/(N-1)) (Sum (V^2))), should be sqrt((1/(N-1))(Sum((V-V_mean)^2)))... anyone else notice this? I work around by outputting the .csv file and computing there. Thanks for any help for feedback.
  4. I've noticed some problems with openlogger and waveforms live: 1. If I try to enter a equation into the analogue channel scaling popup, I cannot enter "mV" for the units. It looks like entry is restricted to a single letter only. That is a bit limiting. Furthermore any scaling equations I enter there don't seem to be saved, so I can't reload them next time I start waveforms live 2. Under the Advanced section, if I save the profile its not there the next time I run waveforms live. Where is it saved to, and how do I retrieve a stored profile?
  5. I am currently trying to implement the related Android Application on the basis of Android phone and Digilent Nexys2 communication. Through the official website I learned that the WaveForms Live device manager enables users to add, configure, and connect to WaveForms Live compatible devices. (https://reference.digilentinc.com/reference/software/waveforms-live/add-device) And I know that Digilent Adept is a unique and powerful solution which allows you to communicate with Digilent system boards and a wide assortment of logic devices. However, I only find the libusb shared libraries
  6. I am toying around with implementing parts of the Instrumentation Protocol on a product I'm developing. I have the web (non-local) version of waveforms live running in a browser window and connected to the Digilent Agent 1.0.1. During the initial connection process when clicking "OPEN" from the Configuration Menu page I see the website (thru the Agent) send: {"mode":"JSON"}\r\n My device then responds with: {"mode":"JSON","statusCode":0,"wait":500}\r\n The website then sends: {"device":[{"command":"enumerate"}]} please note there is no "\r\n". This seems to
  7. A few more info about the Learning Edition would be nice. What exactly is everything contained? Is the housing included?
  8. Hello! I'm excited to announce that Digilent has our first Kickstarter project for the OpenScope! I won't be able to give the project proper justice in describing the OpenScope and WaveForms Live, so I encourage you to check out the Kickstarter to learn more about the mission of the project. With regards to this sub forum, Digilent would like this to be a place where backers of the Kickstarter are able to ask questions and provide feedback for both the OpenScope and the browser based WaveForms Live. As such, we kindly request that only backers of the project ask questions related to
  9. Hi there, In the Kickstarter campaign it's said that the OpenScope will be "open source". Could someone from Digilent specify the licenses that the various files will be released under? In particular, the licenses for the hardware design files, the device firmware, and the Waveforms Live software? Also, will the hardware design files consist of rendered schematics only or the actual EDA design files? Thanks, Bob
  10. I find it both amusing and inspiring how quickly the Kickstarter got funded in just a few hours! Alas, where do you plan on going from here? What sorts of stretch-goals will there be, if any? I would imagine you won't be upgrading the hardware, so as not to cannibalize the market from your other products, but what else is there? Improvements to the software? Nah, those will happen eventually anyway, not a good stretch-goal. Stickers with Digilent-logo or something, like certain companies did with their Kickstarter stretch-goals? Meh, I'd rather like to see something actually useful.
