I got this Schaffner NSG 200E Interference Simulator mainframe with an NSG 223A module a while back to test a device featured in a previous video. That was quite a while ago, but I finally got around to taking a look at it.
In this video we’ll check out the device’s internals and power it on for the first time in years. Then test some USB power supplies for interference (spike) pass-through.
The USB PSUs were the cheapest I could find for fast delivery from Amazon, at about 4 bucks each. I wanted them to be of questionable quality, but they seemed surprisingly well-made. Though I’m not an expert, I am a fan of @DiodeGoneWild and would love to send these over to him for a more thorough analysis if he’d be interested. (Pre-opened and pre-abused, of course.)
