The USB means you can easily transfer waveforms to a PC. The screen resolution is not great, but since its 8 bit A/D anyway, its not a screen problem. Easy to use, and very good triggering and measurement capability. You do need to do a fair bit of button pushing to change X/T/Trigger setups. -- Regards, Adrian Jansen adrianjansen at internode dot on dot net Note reply address is invalid, convert address above to machine form.

I love my old Trio, it is only 10 MHz, but has lasted 30 years without problems, does not have any noise on low signals, has great sync, external and TV too, 2 ch, Bit heavy to carry around, so I put it on the ground next to the desk, no software problems. Got a nice new probe for it some weeks ago: ftp://panteltje.com/pub/scope_probe_img_1845.jpg And you can watch video on it too: http://panteltje.com/panteltje/scope_tv/index.html Perhaps, as CRTs go extinct, the value of analog scopes will increase many fold in the future. So as investment it would not be bad. There are good half analog / digital Teks too, do not remember the number, but 1 G/s and 100 MHz bandwidth was one I worked with.

The storage, the cursors, signal averaging, FFTs, all those things blow away analog scopes. The only analog scope we use any more is our 7104, the 1 GHz microchannel thing. >I love my old Trio, it is only 10 MHz, but has lasted 30 years without problems, >does not have any noise on low signals, has great sync, external and TV too, 2 ch, >Bit heavy to carry around, so I put it on the ground next to the desk, >no software problems. >Got a nice new probe for it some weeks ago: > ftp://panteltje.com/pub/scope_probe_img_1845.jpg > >And you can watch video on it too: > http://panteltje.com/panteltje/scope_tv/index.html > >Perhaps, as CRTs go extinct, the value of analog scopes will increase many fold in the future. So far the trend has been monotonic in the opposite direction. There are a *lot* of old analog scopes out there. I ordered the Rigol. I'll report anything interesting. John
