Dear All,

i'm asking about if there is a "quick and dirty" way to acquire signal from the scope and write their values over a txt file (so i can share and the other people could analyze data using matlab, geant, origin, o wharewere they want). The signal are "almost" square signal with a frequency of 100 kHz and duty cycle between 50% and 10% (so signal "on" for 1us to 5 us). Looking at the redpitaya (i have in lab a 125-14) adc seems capable to do it with a quite high sampling frequency (at least i need 10 MHz sampling frequency). In normal times i would have spend time to figure out by myself how to do it, but i'm quite out of time (and in hurry).
It could be great if there is also a way to set the number of event/trigger acquire (i.e. acquire waveform for 1M of event/trigger).

Data storage could be in the SD card or read directly from lan by a pc.

So some of you could suggest to me if there is some app, code, or guide in order to perform this simple task?

Thanks!

I have a small C program that is essentially a multi-channel analyzer (MCA). It takes input from IN1/IN2 and determines the pulse height (has to be 0-10V), and the pulse height is binned over 1024 channels. So it doesn't save the pulse, but keeps count of how many pulses of height X occurred. The output is stored in a text file in whatever directory is specified, and looks something like this:
There are 1024 rows in the output, with each row corresponding roughly to 10/1024 = 10 mV. When plotted counts vs bin, it produces a spectrum for analysis. Let me know if this is something that could help.
