There’s a lot of test gear out there – each piece of gear comes with its own set of capabilities, form factors, and complexities. There’s so much variance out there that it’s hard to sort out what’s what, even for someone like me who spends all day every day working with it. But, it doesn’t have to be that complicated. Today we’re going to look at a method that I believe will give you a framework for grasping every single piece of test gear out there – a “test gear family tree” if you will. Is that to good to be true? Today we’re going to through a method that will let you classify every single piece of test gear out there, which will give you a good baseline to start from next time you find yourself in front of an instrument you’ve never used before. I also asked folks on the EEVBlog forum to stump me with the weirdest test gear they’ve come across to see if the system can be broken – at the end of this video we’ll look at those and see if this system holds up. This video is also part of the team trees YouTuber initiative to plant 20 million trees by 2020 – every $1 donated at teamtrees.org plants a tree in collaboration with the Arbor Day Foundation, so check that link out in the description as well! Finally, we’re toying with the idea of a scope giveaway at 100k subscribers, so hit like if you think that’s a good idea and get subscribed if you aren’t already! All right, let’s get started. Every piece of test gear falls into one of two categories, they are either an input-based device, meaning they take in information and do something with it, or an output-based device, meaning they take a user input and source out something. – and yes there are blends, but we’ll get to that later. These input and output devices also come in two flavors The first flavor is time-domain test gear – which, as you can probably guess, functions with respect to time, they usually work with parametric systems – like a DMM or function generator, or they work digital signals, for example a protocol analyzer. The other flavor is frequency domain test gear, often thought of as RF and microwave test gear – and thes ... https://www.youtube.com/watch?v=I2-LO8v43BY
