I have a Siglent SSA3021X spectrum analyzer. I like it a lot, and it’s been used for some other posts here. For example looking at LORA signals.
I’ve long wished it had a web interface for screen captures. So I spent some time to develop one, and got it working.
It works pretty well. It’s a bit slow (takes a few seconds to create the images) but I really like it. Much more convenient than fiddling with USB sticks.
All the files and details can be found on my github page here:
