Notes: List price for MSO56 includes digital probes to make it equivalent. 10GSa/s rate for HD6104A is interpolated, actual rate appears to be 2.5. Other options are available, I've just listed the ones I'm interested in. Keysight cliam measured ENOB for LeCroy is < 8. E&OE. Corrections welcome
Probably between the Tek and Agilent for me at the moment. Tek looks pretty good apart from the noise figures and the eye watering cost of some of the extras. The passive probes sound good. The Agilent seems to have better performance and more extensive s/w options. I'd be interested to hear more from people who say it isn't necessarily the best as a general purpose scope and why?
If anyone has an MSOS104A, I'd like to know what the noise floor is when the BW is limited to 20MHz at 1mV/div.
