Comment on Refurbishing a Tektronix TDS7104 Oscilloscopeparent

Comments

As I wrote: the TDS7104 is now sitting on a shelf in the garage, next to an Agilent 54831 and some other boat anchors. My daily drivers are a Siglent scope and a puny TDS220, which is about to be replaced by a TDS3052 that I'm bringing back to life. Hobbyists rarely need more than 100 MHz BW.

I hope you're able to thoroughly test that DSA91304a before dropping $44k on it!

I hope you're aware of the TekWiki:

Mine is a TDS224. Cheap, but I only use it for keeping my Eurorack synth going. 100MHz is overkill for audio. Although some modules use STM32 microcontrollers, so maybe the speed will come in handy.

TekWiki is great!

100MHz is overkill for most hobbyists use cases, and definitely repairing test equipment: it's always the power supply.

TDS220

Cute little thing. The reality is you hope that's all you need.
