Input signals as CSV

[patrick]

Hi,

I was wondering how to work best with sequences for input signals?

In the manual, there is written:

"“File upload”: It enables the upload of the arbitrary signal samples in the form of a CSV file (see Red Pitaya specification document)."

But an example sequence here would help.

Thanks!

Ok, this works great:

There is also an example on our wiki: http://wiki.redpitaya.com/index.php?tit ... pplication

Maybe obvious to others. But i'm confused at what frequency these samples is generated at.

Is it possible to send pulse train signals with the board?
I have to send pulses with pulse with from 25ns to 100µs and pulse break from 1µs to 3ms

for example:

100ns pulse
2.1µs break
125ns pulse
2.0µ break
300ns pulse
2.4µs break

start again with pulse one in a loop

Is this possible?

I dont know if I should buy this board. I need this pulse train function with 25ns (40MHz) minimum of pulse-lenght.

Me again,

on this side: http://wiki.redpitaya.com/index.php?tit ... ad_example
you see a file upload example.

in the csv is this
10
0
10
-5
"generate signal with a period 1/Frequency (1/1MHz=100us)"
but on the scope you see a signal with 25µs time step (40kHz) , so where can i change the frequency for the steps and what is the maximum frequency?

25ns pulses could be generated through FPGA GPIO pins available on extension connector.
Frequency can be changed through WEB application generator interface.

@Črt Valentinčič:

How can I generate the pulses over extension connector with the Web Interface?
I Only found the Signal Generator with FIle Upload and that don´t work with 25ns.

Thank you
