Lab update 2: RIGOL DHO924S, G-EDM pulseboard testing, transimpedance amplifier and more!

A lot of stuff happened in the last week! We got the RIGOL DHO924S after our Analog Discovery 2 burnt up. We also assembled a G-EDM pulseboard, and even got PCBs for the unreleased evo4 version sent to us by the creator. We then spent a while testing and analyzing it, and then developing fixes in the analog feedback path, getting deep into the weeds of transimpedance amplifiers in the process. We work for free on open source, but you can hire us for your project: https://phos.systems G-EDM: https://github.com/G-EDM https://discord.gg/vWSmpkzVrj #rigol #oscilloscope #electronics #engineering
