Was wondering if anyone familiar with the Red Pitaya had successfully calibrated the DC offsets.

You should be able to acquire a "baseline" on any channel, calculate the negative average of the values and apply these to the DC offset values of the EEPROM vector using the calib -w command.

I have tried this it has no effect on the data received by the acquire command.

Thanks in advance.

  • Received an email from my local reseller of the RedPitaya and recommended to set DC offset using the calib -w command. Which is exactly what I was doing, but doesn't work. To get around it, I measured the baseline in my software took the average and applied the offset to signal. Not as elegant as I wished. If anyone has been able to get this to work, please comment. – ldiablo Mar 20 '15 at 00:55
  • I would expect this to get better attention at electronics.stackexchange.com. Perhaps try posting there? – Tullo_x86 Sep 25 '15 at 17:10
  • Thanks... that could be why. – ldiablo Oct 15 '15 at 00:43

A detail buried in the 2018 Red Pitaya Developers guide is that …

The signal from Red Pitaya can be acquired through the acquire command line utility. It will return raw samples from the ADC buffer to standard output, with no calibration compensation.
