  1. Hi @brandonhill7 The average and oversampling needs stable and repetitive trigger. The acquisition will stop if there are no more trigger events and the trigger is set to normal. To prevent the FFT phase alignment to be used, reduce the number of samples to have less than 8 periods, like for 158kHz signal ~4ki samples, or set the hidden option Scope.Trigger.Phase.text = "Xing" for alignment based on trigger crossing interpolation.
  2. Hi @Mike4354 Here the Logic Analyzer detector is set to trigger on DIO 24 falling edge and Pattern Generator outputs a 100ns low pulse on DIO 25 with 200ns (20 cycles @ 100MHz) + Wait time delay. You could adjust the system frequency to change the delay, 250ns (20 @ 80MHz) + With ROM logic the delay is lower, 80ns at 100MHz (DIO 26 is used as state bit) Reducing the ROM frequency will result in delay uncertainty, but delay could be achieved with further state bits.
  3. Hi @SpinWizard 1. Adjust the format, channels and frequency according your hardware specs or requirements. The autodetection of this is not working due to the software abstraction layers. 2. Higher voltage rating would require different protection, certification, costs.... 10x probe increases the voltage range but above 50V with 1x can damage the device. 3. I'm not sure I understand what you are asking for. Do you need digital multimeter with USB and software support ?
  4. Hi @fr.bernardo You can change the CS in SPI/Custom, but make sure to have pullup on these keep the unused ones idle, or you can control from Script tool the SPI and StaticIO. You could also have common CS/CLK and separate MISO, supported only by SPI/Spy. In SPI/Custom separate calls are needed like with different CS, eventually calling ReadQuad for 4 sensors and unpacking the bits.

    Hi,Attila.

    I have learned that VB-8012 has been discontinued and will be replaced with 5250 in the future. Our lab will continue to purchase 5250, but my students have been using virtualbench software before. My question is: Will digilent use ADP5250 in Virtualbench software in the future?The reason for raising this question is that students are more accustomed and comfortable using Virtualbench software

  6. Hi @linc With the 50 V range, the resolution decreases, so a larger hysteresis may be required to reject noise. Use the easier to use acqmodeSingle. The record is only required for streaming for captures longer than the device's buffer size. Use newer software version which provides simple capture up to 128M samples for ADP3X50
  7. In Network Analyzer you can set Source: External and control the sweep from Wavegen or external equipment. The NA will look for peak in the spectrum and consider this the signal frequency. Under Options menu you can adjust the External Threshold, the minimum peak magnitude. Depending or number of Steps, set the sweep time to seconds or minutes, for wide logarithmic scales you can adjust the sweep frequencies manually. When all the step points are captured it will draw a line, until this only dots.
  8. Hi @Andreas Schröck This is currently not possible. Do you need a fixed offset between the two frequencies?
  9. Hi @gcb As you can see in the changelog, beta versions are frequent updates that add new features and fix bugs. The release version comes out about twice a year, usually in sync with a product release, and is tested a bit more. These are useful in class so that everyone uses the version over the course of a semester.
  10. Hi @AlexMark6 You can use the Sweep mode or Amplitude Modulation or a custom waveform but this later one would be limited in resolution.
  11. Hi @AndyMessier See the following: ramp_test2.py
  12. Hi @woldes It shouldn't be that complicated, in Logic select Mode: Record, press the first Config button, adjust the Samples, Rate, Total Time, Trigger positions as needed In Protocol UART tab, use 'Send & Receive' if you are looking only at one uart channel, or Spy for 2 or more, and press Receive.
  13. Hi @gcb You can use the Script tool to automate things or custom app using WaveForms SDK, see DigitalDiscovery_Play Record... examples. and use the latest sw version:
  14. Hi @mat There is no VI for this purpose, but you can use the VI's 'instrument handle' to call the C API
