  1. When using the scope from the Waveforms IDE, I can't get a visual of Channel 2. (Channel 1 works fine) I've tried using multiple USB ports and other computers. When I run calibration for the oscilloscope I get the following error message: "Check the connections!! The measured voltage on Oscilloscope Channel 2 is between: 30.269009276 V and 30.275477712 V. But it should be around: 0 V. It might be that the Arbitrary Waveform Generator 1 Offset is not calibrated correctly." I don't think the waveform is the issue, it reads as expected on channel 1. I could use some help.
  2. Doing a simple lab for school. I am not able to read any measurements for voltage using the oscilloscope when the current is DC but when it's sin or another I can. Any help? nvm. figured it out
  3. Hello, I have a first generation Analog Discovery, S/N 210244626692. It recently stopped communicating with my computer. I have tried different USB ports, different cables, and tried a classmate's AD on my computer. The classmate's AD was recognized by Waveforms, but mine was not. Nothing shows up in the Device Manager when my AD is plugged in. -Nat
  4. Hello, I am trying to send oscilloscope data from the Analog Discovery 2 to the Arduino Uno. Would there be a way I could do this so that the Arduino could read it in live time? Miranda
  5. During device opening internal chips are enabled and configured. This results in consumption increases, specially when the 100 MHz clock (PLL) is started. The needed current increases from 100mA to 500mA. In case the USB can't provide enough current the voltage drops below the minimal required for the device to operate and communication fails. In case you get “Device configuration failed (PLL 1)" or "Communication with the device failed.” error message: The device needs at least 2W/400mA from USB cable. To satisfy this: - Try to use different USB cable and computer plug. - Use the USB plug on the back of the PC, not the one on the front panel. - Use short cable, do not use long cable or cable extender. - Use powered USB-hub, avoid un-powered hub. - Use USB-Y cable to load power from two plugs. Device not detected by WaveForms: Open Windows Device Manager then connect the device and wait up to one minute for a device to appear: - USB Serial Converter, with warning - Connect the device directly to the computer's USB plug without using external hub. - Restart the computer. - Reinstall WaveForms, including the Adept Runtime section. - USB Serial Converter, without warning - Restart the computer. - Reinstall WaveForms, including the Adept Runtime section. - Other application might have erased the USB controller EEPROM (FT_Prog, programming cable drivers...) Use the "My device is not listed" button in WaveForms application Device Manager to reprogram the EEPROM. - Unknown Device Check the Hardware IDs under device Properties, Details tab - USBVID_0403&PID_6014 The USB driver is not installed. - Restart the computer. - Reinstall WaveForms, including the Adept Runtime section. - USBVID_0000&PID_0000 Device not identified or malfunction. See "Nothing shows up". - Nothing shows up: - Connect the device directly to the computer's USB plug without using external hub. - Try to use different USB cable and computer plug. The device or its plug might be damaged.
  6. Analog oscilloscope and a digital oscilloscope - What is it and what else is there? Oscilloscopes have been established since the beginning of the 20th century for the measurement and analysis of a wide range of electrical signals - at that time still known as galvanometers. The word oscilloscope is composed of the ancient Greek skopein (to look at) and the Latin oscillare (to rock). High-frequency electrical signals from televisions, radios and computers are made easily visible with these devices and now the digital oscilloscopes have almost completely replaced the analog version of the market. Other types of oscilloscopes include CCD oscilloscope, mixed-signal oscilloscope, or the more specialized waveform monitor (WFM) in the field of video technology. Structure and mode of operation Analog oscilloscopes use a classic cathode ray tube, whereas digital devices use LDC technology. For digital oscilloscopes, it may, therefore, be the case that the display is larger or even colored. For modern digital oscilloscopes, such a representation is no longer a problem for the better differentiation of the channels. Since with an oscilloscope, especially the temporal voltage curve is of interest, both analog and digital devices, on the one hand, show the voltage signal, on the other hand, the electric current, the frequency, phase shifts, continuity characteristics or pulse diagrams. Digital storage oscilloscopes also feature pre-triggering, multi-value analysis software, averaging, mathematical functions, frequency spectra, statistics, and histograms. Furthermore, the digital storage oscilloscope (DSO) can easily enlarge the view. Scrolling is also possible. Advantages and disadvantages of the analog oscilloscope Due to the built-in cathode ray tube, the difficulty of an analog device quickly becomes apparent here: orthogonal errors, edge blur, pincushion errors and non-linearities are considered classic disadvantages. Added to this is the size of the invention. Advantages and disadvantages of the digital oscilloscope The digital storage oscilloscope (DSO for short) offers some more benefits. It is much smaller in size, no longer requires an inefficient cathode ray tube, but works with LCD technology in an energy-efficient manner, and the display of measured data is more accurate and better. Last but not least, faster processors convince with these devices. Also, modern digital oscilloscopes operate with more advanced signal analysis capabilities, making them unquestionably powerful. Analog or digital - For which purposes is which oscilloscope suitable? DSOs are ideal for high-frequency signals today. With these devices, more extensive functions, signals and frequencies can be recorded efficiently, stored and analyzed. An analog oscilloscope saves the image instead of the signal on the tube, which is far from the case with DSOs. Buy the best oscilloscope but before that read the reviews here in
  7. Hi, I guess I'm doing something wrong but... So using AWG1 connected to OSC1, I can test my board and I see my waveform generated. Done But if I connect AWG1 (solid yellow) to OSC2 (solid blue), it doesn't work, nothing happen when I push the Single button, it doesn't stop until I click on it again and nothing shown. Where is my mistake ? Thanks !
  8. Regarding the oscilloscope on the Analog Discovery 2, is there a maximum amperage the device can handle? I am looking for an oscilloscope capable of looking at the output of a motor driver. While the driver's output is lower voltage, the datasheet says it can be anythere from 0.5-7.5 A per phase of output. If I want to look at one phase, will this level of current damage the Analog Discovery 2 in any way? Or can this device handle the task at hand? Thanks
  9. I'm using the Analog Discovery 2. When I use the oscilloscope, I seem to only be getting a signal snapshot as my output. For example, I ran the oscilloscope for about 1 minute (by hitting "run" and then "stop." I went to the Logging panel and hit "save." I got the attached data as my output. The attached data only spans about 0.1 seconds and also starts at a negative time, even though in my oscilloscope settings I specify that I want time to start at 0 secs. Also, I've tried logging data for different amounts of time (10 seconds, 1 minute, 2 5 minutes) and all the outputs come out to 8192 samples - I would prefer it if I could obtain more samples with an increased length of time sampling. Attached is a screenshot of my oscilloscope settings and logging settings. How do I program the oscilloscope so that I can acquire data over a longer period of time? Thank you so much! acq0003.csv
  10. Hi, I am using the Waveforms APIs to process the raw waveform data from the oscilloscope of AD2 to a C++ code. My other requirement is to use the logic analyzer simultaneously to get the data bit stream of data as well. 1. I was able to do this on the Waveforms 2015 GUI but is it possible using the APIs? 2. There are analyzers (SPI, I2C, Serial, CAN etc.) present in the Waveforms GUI, but is there a preset to do the same in the API? (not just being able to read 0/1 but analyse the SPI/CAN bus) Thanks, Shabbir
  11. Hi, I recently purchased the Discovery 2 and the BNC adapter board (Pro kit). Could someone please clarify where the positive and negative connectors for the scope should be attached when monitoring an AC signal (+/- 12 V). Should the negative connector be attached to the negative rail? And when using the BNC adapter board should the negative connector be connected to ground (because the inputs are not differential)? I wanted to confirm the connections as I had a mishap and toasted my pcb's power supply whilst trying to use the waveform generator and the oscilloscope. Just trying to debug why that happened. I had the oscilloscope's negative connector connected to ground.
  12. Just "discovered" the AD2 and am very interested in it. There is a lot of features packed into a small package. One thing seems to be missing and I was wondering why. There is no external analog trigger. If I want to trigger on a specific voltage in a waveform, I have to use one of the two oscilloscope inputs. Why was this left out? Seems like it would be simple to add a comparator and use a DC voltage from the ADC to set the trigger level.
  13. Hello, i am a analog discovery user and i love the device very much but i am looking for more speed and function. ok now i am proposing a system that digilent should make,lets name it analog discovery 3. i really want more speed,better SDR and a JTAG port inbuilt instrument.
  14. Hello, I have the Waveforms3 beta running on my MacBook Pro almost perfectly fine. I have full functionality of the oscilloscope, wavegen, etc. However, the measurement tool in the oscilloscope on the windows version allows the user to select Channel 1- vertical/horizontal- min/max/peak2peak/avg/etc. On the Mac version, there is no option to choose between vertical and horizontal measurements. It is set default to vertical, so I am unable to measure frequency using a horizontal measurement. I am unsure if I am just unable to find the correct tool or if it is not yet a function in Waveforms3 beta. If that is the case, it would be very helpful if someone is able to write a function that I can input manually into the function to measure frequency. Thank you!
  15. Juergen Sauermann published a classic oscilloscope like application for Linux, based on Qt and WaveForms SDK. This project can be found on the following location:
  16. When I use the oscilloscope to capture a waveform, I need to be able to measure some small features on the waveform. Since the features are peculiar to this waveform, none of the automatic pre-defined measurements are relevant - nor could they be. What I need is the simplest digital feature, one that was first added to analogue scopes about 30 years ago... I would like to be able to manually place two cursors on the screen, and for Waveforms to indicate the equivalent voltage and time of both cursors, plus the time and voltage differences. Ideally Waveforms would also draw light horizontal/vertical lines through both cursors. The nearest I've found to this is that when positioning a zoom window, something similar appears on the display, but obviously that is not the same and isn't easy to use to measure a waveform. What's the best way to achieve my objectives? I'm sure I've missed something simple Thanks.
