Why do you think there aren't more "good" USB oscilloscopes?
<< < (14/17) > >>
Infraviolet:
David Aurora, I know that picoscope USB oscilloscope software is available as a linux version.

As for why not more high quality ones made,  perhaps it is a mattter of the analog parts of the scope being the priciest, and so all the computer stuff built in to modrn scopes is cheap by comparison. To make a profit they might have to still sell a USB scope for just as much as a full scope, and that might well put off a lot of buyers?

This.  Most professional users want a bench scope (I have never seen a USB scope at work), and when a USB scope is in order there are already enough 'good' options available.  There is a pretty big barrier to entry in this market: need to have good hardware, good software, and to chip business away from Picotech need to have either a significantly lower price or some better specs or additional features that people care about. 

There are companies that are trying to do this, for example TiePie

but if you are going to spend that much, do you go with the 'unknown' brand or just go with Pico?

Well, TiePie has been around for at least 3 decades. So this isn't some kind of unknown new brand. To be honest, I'm surprised they are still around; in my mind I was thinking they are somehow relatted to Picoscope but it seems they are not. Anyway, I have used one of their earlier devices a very, very long time ago. At least 30 years ago.

I used Picoscope years ago and really liked it.

I obviously had no idea they have been around that long.   I see that they only have one US distributor, and it is not exactly a well-known vendor.  That may be why they were unknown to me until i was in the market last year.

As others pointed out before my reply, the display is a histogram produced from multiple acquisitions.

Although I wonder now whether the size of the display record has any effect on the processing required since every sample is processed once no matter what the size of the display record is.  It could matter if the acquisition record is decimated because of lack of processing power.
