Recommendation on selecting a used oscilloscope?

(1/5) > >>

nathankwan:
Hi guys, I must admit I am kind of obsessed with good scopes... So please try to focus less on the actual need (I'm working below 100MHz so a TDS220 should be enough in that case, but I just want as much performance as possible as long as the price is acceptable) :palm:

I would like to have an affordable used scope, with relatively good performance and endurance. I've done some digging and got this list:

> TDS3000B series, or more precisely TDS3014B, with easy upgrade through ethernet.
> Lecroy wavesurfer 44Xs (or similar), would also like to upgrade sample rate but just don't know how (I've seen someone succeeded).
> TDS784D/794D, just like its color CRT...

But I also have concerns about each one above:

> TDS3000 series have shallow memory depth and crazy-low waveform refresh rate, but their price are around $500 in where I am.
> I love Lecroy's enclosure size and Windows OS, wfm refresh rate is high, but expensive (around $1500, old 7300A are cheaper, but so heavy).
> CRT attracts me, memory depth and wfm refresh are fair, but too heavy, and only 1GS/s when all channels on, etc...

I came here to see if anyone can share some other models that I'm not farmiliar with, like Agilent/Keysight, R&D, Siglent(I don't really like), RIGOL(I don't like either),  YOKOGAWA etc...

You and me both.

Please tell why ?  :-//

My first DSO was a Tek TDS2102B (now busted) and later had my hands on TDS210 and TDS10**B I don't remember which model, 60 MHz IIRC but they were both busted and then repaired and sold.

The earliest Siglents we had 11 yrs ago were easily as good DSO's as the Tek's and in my experience have proven to be more reliable.
You should take a long hard look at SDS804X HD ......

The new 12-bit Rigols/Siglents are far better than anything you'll find second hand for the same price.

Having owned a bunch of different "hobbyist" oscilloscopes over the years: I agree completely that you will probably get a lot more bang for your buck just buying a new hobbyist scope versus buying a used scope.  Even scopes I bought new 10 years ago look pretty ... sad ... compared to what I could buy today for the same money.

Huge difference between buying a 20 year old multimeter and a 20 year old oscilloscope :)
