We just got a new Tek TPS2024 scope. It's a 4-channel, 200 MHz color

you can use regular 1:1 or 10:1 probes for off-ground measurements at
millivolt sensitivity. Slick.

The 50:1 attenuation of the P5205 turns low-level stuff to mush.


Yeah, another thing I'd like is something with less attenuation.

Those isolated input scopes are really nice. Too bad they didn't put in at least a bit more sample memory. The TDS3000 series is really looking pale compared to Agilent's 6000 series. But both now have lower priced scopes. They seem to be not bothering to compete at the low end with record depth, but just color, screen res., and speed. Not that those aren't yummy on their own! It's really awesome what's available compared to a decade ago.

I just hope something like the MSO6014A will be about half the price in about 5 years.

John, why didn't Tek publish CMRR figures for that scope? Have you done any tests?


Good day!
