ChatGPT has changed everything in the space of a month. 2023 will be the year of Conversational Search and computer code generation. And how MidJourney and DALL-E have rendered artists obsolete, or at least turned ANYONE into a great and capable artist. This video thumbnail was generated in seconds by Dave who has ZERO artistic skills. Why The Chaser is setting up a futile paywall to stop the AI invastion. https://chaser.com.au/uncategorized/why-the-chaser-is-going-to-put-up-a-paywall/
This video is a response to a forum question that asks if the RP2200 150MHz probe supplied with the DS1054Z is degrading the performance of the scope compared with the 350MHz RP3300 supplied with the DS2000.
Are there any performance differences between the two probes on a 100MHz bandwidth DS1054Z?

Les Thomaidis shows and explains the calibration rack at the Agilent Melbourne Standards Lab that is used to "calibrate the calibrators". This is where other calibration labs send their multimeter and oscilloscope calibrators to get calibrated.

A teardown of the front end PCB in the HP 35660A Dynamic Signal Analyser.
Dave does some preliminary investigation to see what opamps and FET's are unsed in the analog front end to see if they can be upgraded for better performance.
This is more for Dave's record than interesting info.

Eagle PCB CAD software, now owned by Autodesk have moved to a subscription model. No internet = No Eagle for you!
This is likely not going to end well for Eagle.
There is also a new pricing model.
CORRECTION: I didn't take into account the yearly pricing in the new model vs the one-off cost possible with the old perpetual license. I assumed everyone would continuously update and that's not always true.
