Re: OT - Any interest in starting a Tektronix Logic Analyzer Group? (with added bonus question!)

Hi Harvey; I don't follow... a common (and relatively cheap) protocol analyzer, such as a Beagle ( https://www.totalphase.com/products/beagle-i2cspi/ ), shows protocol details/data, and timing, with a little USB dongle. I have the I2C/SPI version, and the USB version. Works great for those specific serial buses.
Am I missing your point?
Application example: A few years ago at HP, working on a storage controller that included a large SoC chip that included I2C for controlling power regulators in a startup sequence. Vendors docs were not detailed enough, and my power system design was a little different from their Reference Design, so there were issues. I used a Beagle to see and capture exactly what it was doing on power-up...
Simpler example, which I've needed multiple times: A CPU is trying to talk to something, but the I2C address is wrong. A Beagle immediately tells me what it's trying to do.
