I've configured the two PDA's to the Red Pitaya. I put a 50 ohm resistor connector to each red pitaya input port. This was because the oscilloscope showed that the voltage reading from the P polarization PDA was almost at 1V, which was the limit of the red pitaya. Once both S and P polarization PDA's were connected, I opened the red pitaya's oscilloscope. A screenshot of the voltage readings is shared below. Channel 1 (Yellow) is for S polarization. Channel 2 (Green) is for P polarization. It would seem that there is a significant amount of polarization in the P direction as opposed to the S direction. I then tried running the template time series measurement within the python notebook from channel 1 only. The python notebook graph is shown below. I have not figured out what are the units of time on the x axis, and I have not figured out how to change the amount of time that the red pitaya takes data. A plot of the time series measurement is shown below.
