There's a lot of nitpicking about the details going on in this thread, and it's very interesting to read.

But I think the gist of the post is that the hardware cost of a high end ultrasound unit is rapidly decreasing due to advances in ADC technology and the general trend of moving more and more functionality into DSP that used to require specialized analog circuitry.

For example, I recently bought a 20MHz spectrum analyzer and oscilloscope with built-in tracking generator for $145. Gear of similar quality would have cost tens of thousands of dollars just a decade ago.

That's really nifty, I've got a Serious Business(DSOX-3014A) scope but could never justify a spectrum analyzer. I've got the signal gen so I've though about rigging up their API to do a simple sweep but never got around to it.

For filter work that'd be near perfect.


How's the UX on that? I kind of prefer having physical knobs and buttons, but I can imagine having better analysis and capture outweighs it.

Maybe I should get one of those and a USB DJ controller for input.


The UX is pretty good. The utilities seem to have originally been created for the Chinese speaking market but there are English language versions of the software that are very easy to use.

Good idea about mapping some knobs to the UI.

I've used it to measure harmonics when testing some low pass filters, and the readings match some other gear I own.

Nice. Does it work under Linux too?


I'm not sure. I resorted to buying a copy of Windows 10 to use with certain software and utilities that seem primarily supported on Windows.

The windows software seems to be under active development and I was able to skype chat with one of the engineers before I bought it to ask a few questions.
