We've just got some new analogue circuit boards. This post is about how we're testing them.
Analogue Boards V2.4

Three of our prototype new analogue amplifier boards

You can find the design files for them here. How to test a new hardware module? It's a good question. Here are the stages: 1) Visual inspection of the assembled PCB's (these were manufactured and assembled by Seeed studio using their Fusion service - you can find it here: A signal pulse from a single SiPM

One SiPM pulse measured on the oscilloscope. Note that the timebase is wrong, it should be 200ns
