You know, I bought an R&amp;S 50MHz mixed-signal scope that had the ability to software upgrade to 100MHz. It&#x27;s more expensive than the Rigol, but the UI is miles ahead of Rigol as well.<p>Anyway, I was pretty happy with it and used it at 50MHz until one day I needed the extra speed to debug a higher speed glitch. Quick call to my distributor, pay a couple hundred bucks, and I instantly have a faster scope on my bench.<p>Part of me is grouchy that it was just a product key to type in, but honestly, I have a great tool at a reasonable price point and I didn&#x27;t have to pay for the extras until I needed them.<p>Could I have just hacked it? Probably. But I&#x27;m making money using the thing, it&#x27;s a tax writeoff, and I don&#x27;t mind paying for well-made equipment.
