Hi there, I hope that you are doing well. Currently, our application uses python code to save the acquisition file (parquet file) on raspberry pi. The problem is that this procedure takes a lot of time (some ten seconds). Therefore, we wonder that there is any solution that can save directly the file on DDR3 using Python? Thank you in advance for your advice. Best regards.

Hello, Hope that all are doing well. I wonder where I can find the BOM of Digital Discovery. Thank you in advance for your reply. Best regards.

Hi @zygot, This means that I can modify the amplitude of each harmonic. Thank you in advance for your reply. Best regards.

Hi, Happy new year. I would like ask if it is possible to generate a 50Hz signal with adjustable harmonics (3, 5, 7, 9, 11) with Wavegen in Waveforms software? I use Eclypse Z7 with Zmod AWG 1411. Thank you in advance for your reply. Best regards.

Hi, Wishing you a prosperous New Year. I'm intrigued by the capabilities of the Eclypse Z7 with Zmod AWG and have a technical query regarding its potential in generating a 50Hz signal with adjustable harmonics (3, 5, 7, 9, 11). I'm curious to explore whether this is feasible and, if so, would greatly appreciate guidance on the steps to achieve this functionality. Thank you for your anticipated assistance. Warm regards,

Hi @attila, Thank you so much for your advice. The system runs very well with your solution. I would like to ask how I can implement the interpret the data according the clock with the normal capture mode using WaveForms SDK? Which function should I use? Thank you in advance for your reply. Best regards.

Hi @attila, Thank for your answer. I have tried and received something like in the photo below. I have one question. You said that the difference is the crystal oscillators tolerance. So the PPS period that I got is 1.00000385 s and not exactly 1s is because of the crystal oscillator of the digital discovery and not because of the GPS precision? That is it? Thank you in advance for your reply. Best regards.

Hi, I hope that you are doing well. I would like to ask if it is possible to make a counter to count between two pulses in Digital Discovery? I want to use PPS (pulse per sesond) from GPS to trigger the acquisition. And I want to use a counter to be sure that the duration between 2 PPS is exactly 1 second (with 10ns precision or less). Thank you in advance for your reply. Best regards.

Hi, Thank you so much for your reply. Do you have another DAQ that can accept 100MHz eternal clock or can create a 100Mhz clock? Thank you in advance for your advice. Best regards.

Hi attila, Thank you for your answer. If I use extenal clock for the ADC and take digital data to DAQ, do I need to sync the clock between ADC and DAQ? Because when I use the 50Mhz clock from Digital Discovery to supply for the ADC. Everything is fine. However when I use extenal 100Mhz clock for the ADC and I show some errors like this. Is it because the clock is not stable or because that I have not synchonized the clock between ADC and DAQ? Thank you in advance for your reply. Best regards. P/s: I use ADC https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/dc782a-t.html Clock https://www.mikroe.com/clock-gen-click Bit 15 is the clock signal.

Hi, I hope that you are all doing well. I would like to ask that if it is possible to sync the sampling clock of the Digital Discovery with an external clock? Thank you in advance for your reply. Best regards.

Hi, I hope that you all are doing well. I would like to ask if it is possible to output 100Mhz clock from Digital Discovery or not? Thank you in advance for your reply. Best regards.

Hi community, I hope that you are all doing well. I have a question that I would like to ask for your advices. Is it possible to + sync the acquisition starting point of 2 Digital Digilents + timestamps the data received using signals directly received from the GPS modules? Or will we need an additional microcontroller to process the signal from the GPS modules? Thank you.
