[TriEmbed] MSO may grow on you Re: Budget minded oscilloscope

[Pete Soper]

I have an MSO2072A and it has all the options except this one they just 
started advertising. But it may not actually boost bandwidth from 70 to 
300MHz, I may have read that into their web site blurb. Waiting to hear 
from them. Not holding my breath. Sometimes you get unlucky with 
marketing changes. When I bought the scope I was told I could upgrade to 
300MHz, but then the truth changed. I don't blame RIGOL and certainly 
not Tequipment (bought a LOT of stuff from them and like them a lot). 
But the notion of being able to watch the the RP2040 at full tilt got me 
excited. :-)

But this model is old as the hills. Bought it in 2015. It appears the 
current equivalent might be the MSO0572.

I can honestly say in almost six years I've never been in a situation 
where I said to myself "I'm so totally hosed because I don't have a 
third analog channel". But had I not had the digital signal capability I 
would have been hosed a lot, and even with four analog channels.
