Tektronix 465 vs 2236 Scope

(1/2) > >>

Hi EEVblog! I watched Dave's buy a analog scope plz video and decided to do that instead of jumping into a DSO right away.

I have found to possibilities that I am considering.

First up is the Tektronix 465 scope. It appears that it cost around $110-120. It comes with 2 new 100MHz 10x probes and has been professionally calibrated.

Next up is the Tektronix 2236 scope. It will cost $180. It has supposedly been used by an electronics specialist and is said to work perfectly. It comes with 2 new 10x 250MHz probes and has the integrated DVM frequency/timer included.

Both are used. I plan to use this scope with Arduino and the Make Controller development along with other micro stuff. This will be my first scope so I would like to get something reasonable which will keep me busy for a while before moving DSO.

What do you think?

DJPhil:
Both are excellent scopes, and those look like pretty good deals. Assuming the 2236 is in good shape that's probably the one I'd go with, though some might disagree. The quick and easy parameter readout is easy to get used to and easy to miss, and would be worth more to me than a fresh calibration assuming it was at least close.

If you're going to be working primarily with micros as opposed to lots of analog stuff I'd have to say it might be worth saving up for a Rigol or Instek. Analog scopes are great to learn on and have their own useful niche, but the lack of single shot capability is a real drawback for a lot of digital work. I picked up a 465B on craigslist a while back as a first scope, and I can honestly say that while I've learned a lot I'd have a much more comprehensive tool if I'd have saved for the Rigol. If money's not really a problem then go for it, nothing wrong with having an analog and a digital scope!

Hope that helps. :)

I'd get the 2236. It's a better scope in every way. I have one and I love it, but then again, I dont have experience with the 4xx series. The 2xxx series might be slightly more difficult to service.

The counter is handy if you don't have a dedicated unit for that.

edit: Although, consider what DJPhil said. A DSO might just be a better investment for the future...

thakidd:
Hrm...I think I am with both of you on investing with the future as my primary goals surround micros and repairing digital type stuff.

One question though...If I go with the Rigol DS1052E in Dave's videos, is it still hackable?

EEVblog:
I'd get the 2236, it's a much more modern scope, so stands a better chance of surviving much longer.

For micro work though you'll find a DSO much more useful. But of course it's more than double the price.
But a nice analog scope will never go to waste in the lab.

Dave.
