  1. I am a hobbyist, new to oscilloscopes. I recently purchased the Analog Discovery 2, the BNC Adapter and the BNC Oscilloscope 1X/10X Probe pair. I've read this post and this post, and followed this video on calibration, but, I'm not sure the AD2 and/or the probes are measuring properly or not. I cannot get square off the signals. The screenshots indicate the maximum I am able to deflect the signal when rotating the screw within the probes. From my understanding, rotating the screws in the probes should make the signals become square. Here's other information which may be indiscern
  2. Dear All, I am confused about the calibration process of PModIA module with Arduino board. I am using a program from Github, please check that. Also tell me the use of SEL pin in the board. Can you please tell me step by step procedure... ad5933-test.ino
  3. Documents for the DMM Shield states an accuracy of +-0.1% for voltage, current, and resistance except for specific ranges highlighted. Is this accuracy obtained with factory calibration only OR does the user need to also need to calibrate the equipment? If the user needs to calibrate, can the calibration factors be stored and used by Shield OR is a external program required to make adjustment in real time. At the moment, the Shield fails to produce comparable measurement with a Fluke 88V that has lower accuracy for current and resistance readings. For the voltage readings, the accuracie
  4. 1) How frequently should an Analog Discovery 2 be recalibrated? 2) Can devices be sent to Digilent for recalibration, or can Digilent recommend a calibration lab? Thanks in advance! Chris
  5. Just a note after struggling with a failed calibration. If the red LED goes out after 4 seconds into the calibration, it might be a bad USB cable.
  6. Hi Digilent Im currently working on my finals in electronics development, including a hardware setup and a custom-made C++ application for my Analog Discovery 2. However it seems that the calibration data made with WaveForms does not apply to the hardware when using custom C++ applications. I've been looking through the manual and haven't encountered any examples of how it is done. I hope you can help me Kind regards Rasmus Pforr-Weiss, Brüel & Kjær SV
  7. I recently went to use my Analog Discovery 1 and I found that it was giving me all sorts of strange results that I did not expect. I figured that the calibration must have drifted since I hadn't used the device in a year or so, but when I performed a calibration it was still significantly off. Here's a link to an album showing comparisons between the AD1's readings versus a multimeter: https://drive.google.com/open?id=0B2q6FpLmYUaVb1dQSFpIQVJYWXc . I don't really know what to do at this point, but perhaps someone here has run into this issue before and can recommend a fix. Thanks! Edit: F
