Maybe after 10 year from now agilent will copy rigol and do funky equipment

I do agree the other stuff (scope etc look very nice, excellent in fact). But that power supply is like a pizza that won't stay down.

next up after colour lcds on psus: touch screen psus.

I am actually surprised we haven't seen many cheap rubbish touchscreen-only (no knobs) instruments until now. There are these nano DSOs, but that's about it. Smart phones and tablets made touchscreens a cheap consumer technology. Stuff like this http://www.ebay.com/itm/360500650084 (1080P 4GB 4.3" touchscreen video player) can be had for for $30. But for some reason the technology doesn't appeal to the cost-obsessed junk instrument manufacturers.

And it's quite amazing if you think about it, B@W. Rotary encoders are more or less expensive mechanical parts and these resistive touch screens can be had for the price of a single encoder.

Oh, I prefer buttons to touchscreens... My DSOX2002A is so intuitive that you can use it even without looking at the button panel. You use only your sense of touch.
There are scopes with touchscreen, but they still have knobs.
Amazing machines. https://www.youtube.com/user/denha (It is not me...)

So do I. E.g. I hate USB oscilloscopes. One reason for that is that they don't have knobs.

But the point was that junk instrument manufacturers are cost-saving crazy, and don't care much about ergonomics. So it is a bit surprising that there is no wave of touchscreen-only instruments from these manufacturers.

Yes, I know, e.g. from R&S. But they have "everything", touchscreen, traditional knobs and allow to connect a keyboard and mouse.

They probably don't like to innovate all that much... "since the western scopes (Agilent, Tek, LeCroy, etc.) all have knobs, ours should too".

Although pinch-to-zoom to adjust the timebase and V/div scales might not be all that bad for the iPad-using crowd... no, I'd still want knobs for everything else.

One may consider that e.g. for Android tablets, designers are looking at housing a generally generic PC that can run the OS, so most R&D is in ergonomics, size and power reduction; they can easily contract subsystems for bluetooth, wifi, USB etc.,. already used by other makers that in economies of scale, can make them affordable to include.  But in T&M, a good fraction of a design budget is in fundamental measuring capabilities, say as a DSO, plus regulatory approvals are far more taxing to pass if not more numerous.  Add to it, the T&M market is smaller, the device service life longer, and the actual experienced device designers for that type of gear, much less numerous.

second - in my opinion rigol is not chinese , rigol is the US presentersin china  :clap: ( Kiethely yokogowa and Yamaha are good chinese companies which in my opinion are high end and some good value per $$ )

rigol is some good company - they are good competitors and high value in my opinion


Umm Keithley is an American company and I'm pretty sure Yokogowa and Yamaha are Japanese...

Except that in reality it is a 720p video player, with the collection of characters "1080p" thrown in there. You know, make some more money from people thinking they get a real 1080p player. It says it "supports 1080p". I guess they forgot to add it also "supports 4k UHD". Now it may choke on that bitrate, but hey it supports it. Still, $30 for a random 720p player isn't bad...
