Take #2 for the front-end calibration

Looks like there is a new SD card image available in the Red Pitaya site (thanks to Dashpi for pointing that out).



The new version should have an automatic calibration included in the oscilloscope app.

The image file can be downloaded from the Red Pitaya dropbox:



Let’s download the zip-archive and extract it to an empty SD-card.


Then let’s plug in the SD-card, connect the ethernet cable and the USB-power cord.  And see that happens.

First,  the syslog from the linux mint box tell’s me that it has allocated an IP address to redpitaya. Looks good.

Now I should be able to start firefox and go to address


Yes, seems to work fine so far.

Let’s try to run the oscilloscope (50 Ohm terminators used in the input ports).


Nice. The DC-offset seems to be automatically compensated. So no need to run the calibration scripts anymore.
