You asked me before, to measure the -3dB point of my 1 GHz MSOX3104A
Here are the pictures of the measurements
I am using my trusted 3.2 GHz Agilent 8648C for a sine wave output, 50 Ohm in 50 Ohm
My MSOX3104A has the -3dB point at 1.16 GHz

Incredible work. A huge boon for the hobbyist, and I doubt this will impact commercial sales one iota.

Seeing as how this has a BOM of only $200 retail, it really makes the market segmentation pricing seem absurd at this point.

Next generation entry point of the 3000 level scope should be at least 500Mhz, with a path to 2Ghz or higher.

Impressive mod! It probably won't impact commercial sales like you said, but it's a great pathway to 1 GHz for guts folks.

A 1 GHz scope price has as much to do with design and NRE as BOM, and that tech trickles down into the lower bandwidth models. So, if we dropped prices on the high bandwidth models, the entire line would stop being feasible. Designing a 200 MHz scope is much, much easier than designing a 1 GHz scope. And, as is made clear by the mod, the whole backend of the scope is capable to 1 GHz (or higher  >:D)

I wouldn't bank on a 3000 level scope starting at 500 MHz for a long, long time. I won't go into sales details, but for basically every line of scopes all the way up to the top, we sell a lot more of the lower bandwidth models than the higher bandwidth models.

Maybe because everyones hacking them. :-)    Probably because in all reality your average workshop/lab doe'snt need too many 1Ghz Scopes.   We have 4 100Mhz scope and 1 500Mhz Scope. The 100Mhz scopes are the workhorses and do 95% of the work..  They are cheap enough that you can leave them sitting on a bench, and not have to move them around.    the 1 500Mhz scope is on a trolley and gets moved to where its needed.    Not sure if this model scales out, but it works for us.

Bandwidth: if you need it, you really need it. If you don't? Well... save a bit of brass and maybe buy SPI/UART Decode and MSO  ;D
