  Give it a month and the acquisition ASICs will blow up and the caps will eat through the board traces. Can’t stand these scopes.

  Flebay has some used ones around $1.5k. I wonder how much this model MSRP brand new? Either way, $300 is a steal!

    I think they sold for $60k back in the early 2000s.

  The TDS500, 600 and 700 series can expand memory by removing zero ohm resistors.

    My TDS754D is waiting for the resistor and capacitor mod that converts it from a 500MHz/2Gsps scope into a TDS784D with 1 GHz/4Gsps.

    Still, entering an easy to generate license key is less intrusive than removing a resistor.

  Love this. I knew nothing about oscilloscopes until just a few months ago, when reasearched and bought one from a science lab. It wasfor a personal side project. I gutted it out and installed a mini PC inside, and now i run AI models into it. It's like my personal AI assistance. Hooked up to OpenAI realtime voice, grok bot, claude code, etc so I can command it to do stuff even when my main computer is off.

  I just mainly love the retro-moder look of it. Here's a link to how it looks, for those curious:

  I had now idea there was such a huge second-hand market for those. It was such a great opportunity to learn about this tech.
