Hi,
I am new to this RP environment and I am trying out some basic stuff to get to know about the board. My doubt is over the jumper positions for the analog inputs.
Should I change the jumper positions to plus or minus 20V option to enable to RP to measure input signals having Vpp > 1 Volts?

Re: Analog Input Jumper Positions
Hello Hariharan
I too am a Newbie just starting out with a RedPitaya
I too am hoping for an answer to this question. Possibly like you, I dont want to 'fry' my new Christmas Present by making stupid mistakes right at the outset.
I would like to hope there is some 'over-voltage' protection on the inputs. BUT until I find it in writing I do want to take a chance!
Happy New Year

Re: Analog Input Jumper Positions
Hello,
as stated here : https://redpitaya.readthedocs.io/en/lat ... %20jumpers
important bits being: Absolute maximum input voltage rating: 30 V (S) (1500 V ESD- electrostatic discharge) and if you click the previous link and scroll a bit you will find explicit pictures explaining how the jumpers work.
I am also a electronic hobbyist and my rule is to keep any kind of instrument on the biggest range, in this case is the +-20V option, just to be safe, and I will use the 1V path only when I already know for sure that my signal is under 1V and I actually need the extra resolution and accuracy that this range provides.
Hope this helps!
