Thank you very much for the reply @Fausto, Just to be sure about how to handle the data update from the python script (always referring to the uldaq-1.2.3/examples/a_out_scan.py example): Let's say I have in the buffer A*sin(omega*t) for one second, then after 0.5 s I receive an input and I have to update the signal to A_2*sin(omega*t) does the output instantaneously switches to the second waveform or it waits the end of the previously set 1 s interval to change? Thanks again, Apl

Hi, I anticipate that I am new to DAQ devices. I'm looking for a product that meets the following requirements: 1) Work on a Linux machine 2) Have a Python API 3) Be able to acquire voltages at a sufficiently high rate (>=100kS/s) 4) Be able to generate an output signal of a desired waveform (sinusoidal, sawtooth, etc..) 5) Be able to change some parameters of the generated signal (e.g. amplitude or frequency) from a Python script, as some specific inputs are detected. In this list https://files.digilent.com/manuals%2FLinux-hw.pdf I saw products like USB-1608GX-2AO which seem to do what I need. However, it is not clear to me how this type of device can be used as a signal generator controlled by the Python API (https://github.com/mccdaq/uldaq). I have seen the 'uldaq-1.2.3/examples/a_out_scan.py' example for generating a waveform and it is promising, but I was wondering if there is a way to simply output a given waveform and then update (for example) its amplitude as I would do with a knob, without having to generate the data each time I need to update. Do you have any suggestions? Thanks in advance Apl

Hello, Just subscribed to the forum. Hope to have interesting discussions about MCC DAQ products. I'm a post-doc in physics working in a large laboratory in the Paris region. Together with some colleagues, we are looking for new solutions for our experimental setups. Apl
