  1. I launched a test panel in MAX and saw a signal from a 1.5V AAA battery. I saw the same signal from battery when I opened LabVIEW built-in example 'Voltage-Continuous Input.vi'. And after all that I launched this Main Selection Window and saw a 1.5V reading on it, so now I'm confused why I haven't seen a signal when I was trying to acquire a signal from a wall socket using high-voltage probes. Edit: When I launched built-in example 'Voltage-Continuous Input.vi', I have seen a signal from a wall socket, but I haven't seen it when I launched this Main Selection Window.
  2. I tested it, but it fails to give me accurate signal from the voltage probes. I just see some noise, not the real waveform of input signal. I guess I will have to edit part of Main Selection Window regarding DAQmx.
  3. Thanks for the info, I will try to test it sooner rather than later. If I want to add a high voltage probe ratios (voltage dividers) into account, I guess I should add a case structure in Main Selection Window.vi (lower section of the block diagram which encompasses DAQmx, more precisely inside the while loop)?
  4. Hello, I tried to test my VI in lab, you can see it attached to this post. Although it is executable with no errors, it doesn't work what it is supposed to do. It only works when one signal is being manipulated on DAQ card, but not if more of them. I guess it's because DAQmx can't handle more then one DAQmx Task at a time. Is there quick fix for this problem or I should do a completely new thing from scratch? Version1.rar
  5. Thank you very much for your help, now I get the better idea of how my front panel and block diagram should look like.
  6. When you say transparent tab, you mean Tab control in Controls Palette? How do you mean 'depending on what they selected at the start'? Which step is necessary to do selection at the start? If I am right, using subpanels can make this easier, and I can select what type of display do I want, and then simply get that view in a new Front Panel. But how does a single signal can be reentrant and spawn all the clones I need? I don't get it, in fact I am not sure if I understand what did you want to say. 8 separate VI's includes 8 VI's (first for one channel, second for two channels, third for three channels and so on...)? Do I have to select channels somewhere before, or just click on the button and VI is opening according to my selection?
  7. WHen you say decent amount of work, what exactly do you mean? How much is needed to make this Front Panel? Which one of these ways is the easiest one? I am thinking on thrid option mentioned, but I don't know if I am missing something...
  8. Hello everyone, I have a question about designing a customizable front panel for data acquisition cards. I already have 3 virtual instruments, one which will display waveform of input signal, one which will display numeric values of input signal (peak-to-peak, +peak, -peak, DC, RMS), and third one which shows numeric values and waveforms of input signal. Those three block diagrams are similar to examples which can be found in LabVIEW Help tab (Help->Find Examples...). But, the problem is next. Now I need to create a front panel which will ask me how many inputs do I have (it can vary from 1 to 8), then it should ask me what do I want to see (numeric values, waveforms, or both) for every single channel, and in the end it should show me my preferences in a new (or same) front panel. For example, I select four inputs, then I select waveforms for input 1 and 2 (because I want to see waveforms of signal on inputs 1 and 2), and numeric values for inputs 3 and 4, and then my front panel should be divided into four sections, on the left side there are waveforms for inputs 1 and 2, and on the right side there are numeric values for inputs 3 and 4 of my DAQ card. Any ideas how to achieve this? Thanks.
