    PYNQ-Z1 Capabilities

    Hi all, My group and I are brand new to FPGAs, none of us have any expertise whatsoever. As such, we have a few questions about the capabilities of the PYNQ-Z1 board that some of you seasoned experts can help us out with. First: we will have a TTL (3.3 V) pulse sent to the board which is about ~10 ns long. Can the board detect such a pulse from something like a rising or falling edge? We hope to send this pulse via BNC connection - where could we input this on the board? Second: We also need to output a pulse via BNC connection. Where would this pulse be outputted from? Third: Given the first two questions, should we invest in the following two items? i. https://store.digilentinc.com/pmod-cable-kit-6-pin/ ii. https://store.digilentinc.com/bnc-adapter-for-analog-discovery/ Sorry if these questions seem hopelessly basic. We are new to this type of hardware and would greatly appreciate any help you all could send our way.
  2. I work for an Electrical Engineering Program at a University and we are considering using the USB scopes from Digilent in one or more of our labs. However, we need to know if they can do the following things: Please note that I am not an Engineer, more of a procurement specialist. I have done as much research as I can understand and have posted my findings, but I am not qualified to pull 100% reliable answers from the documentation, so any help is greatly appreciated. 1. The ability to display and capture (for lab reports) analog waveforms in the audio frequencies (22kHz+ up to 100KHz). From the sales data sheet it appears that this is possible: Analog inputs go to 5MHZ: Two fully di­erential channels; 14-bit converters; 100 MSPS real-time sample rate • 500uV to 5V/division; 1MΩ, 24pF inputs with 5MHz analog bandwidth 2. The ability to display and capture (for lab reports) spectral plots in the same band as above. Again from the sales sheet, this appears to be possible: Real-time FFTs, XY plots, Histograms and other functions always available 3. The ability to average several spectral plots of the same signal to reduce noise in the plots. 4. The ability to generate white noise. I have been unable to find anything concerning these last two needs from documentation I have been able to find on digilent.com If anyone knows about these capabilities, I really appreciate the help.
