  1. actually i have been working on remote lab since last 9 months and i succed a lot inorder to minimise the setup of mine remot elab i am trying to connect mine analog discovery kit 2 with raspberry pi and i have installed the debian file of wave form setup its not working properly the issue what i am getting is the since analog discovery kit 2 is usb based oscilloscope and wave form generator so when it is plugged in with pc it is properly getting the required amount of current from the pc to usb but the same analog discovery kit 2 i am connecting with raspberry pi the current delivered from the raspberry pi is not appropriate enough to runt the analog discovery kit so how can i resolve this issue please help i could able to resolve this that i will be more efficient setup for for me to work on mine remote lab , and same thing i developing mine project on labview using the labview connection with arduino.please help.what error coming while connecting raspberry pi with analog discovery kit is inappropriate current rating PLL stop working.
  2. Hello, I'm a bit confused as to how the Waveforms manages its buffer. I'm using the Waveforms SDK (via LabVIEW) to both generate a pulse and act as a scope using the Analog Discovery Kit 2. I am generating a 50 ms, 5V pulse with a frequency of 230 kHz. This is connected to a hardware device. I then want to use the scope function to record the output form this device. I can get the scope to read, but I don't really understand why it works the way that it does. As it stands, the only way that I can consistently get a waveform is as follows (AnalogIn): AutoTimeout: 0.5 Sample Frequency: 160 kHz AcquisitionMode: Record RecordLength: 2 seconds I also have a 2.5 second wait on my analog out. If any of these settings change, my waveform will not show up. If perhaps I want a 200ms pulse, I need to change the sample frequency to 40 kHz. Attached is a screenshot of what the waveform looks like. There are two problems with this. The waveform is pushed far to the right. I want the waveform to take up the entire buffer. Second, if I'm sweeping frequencies, the waveform will show up at slightly different spots between frequencies. My ideal situation is that the ADK2 outputs a pulse, and when the pulse starts it immediately begins to record, filling the buffer after 50 ms. This buffer is emptied into an excel document, and then awaits use again. I've searched and read through the SDK reference manual but I can't seem to get a grasp on how to fix this. I feel like it's a lack of understanding of how the buffer is managed, but any help would be appreciated. Thanks EDIT: Follow-up/related question: How would these settings translate into SDK functions?
  3. Hello, I am creating a program in LabVIEW that is supposed to accomplish 2 goals: Generate a 50ms pulse using the Analog Discovery Kit 2. The pulse being generated is a 0-5 V square wave with frequencies ranging from ~220 kHz - 230kHz. This component works reliably and I have this completed. Then, use the ADK2 oscilloscope to read and save the data to file. The scope will be attached to secondary hardware which is generating an output. However, I am running into an issue with getting data using the AnalogIn components of the Waveforms SDK. Simply put, it's not working. I want to record for the 50ms that the pulse is being generated, perhaps with a bit of buffer before and after, like 2 ms. That's not necessary though. Even after the data is recorded in labview, what would be the best way to output this to Excel? I think you're supposed to read off the AnalogInStatusData function?Any help would be appreciated. Thanks.
