RE: [neonixie-l] Need advice on a new scope...

[theoldphart2]

I have in my basement an unbuilt Heathkit 5 MHz scope! (Flea market find!) 
Interested? 😊 (I was thinking of using it to build a scope clock, but the thing 
will be huge)

 

If you are not used to a digital scope, they do have a learning curve although 
the number of on-screen measurements and hold functions are awesome. Yet I 
still often go back to one of my analog scopes, especially when working with 
low frequency stuff. Whatever you do, try to fix the old scope, and keep it 
handy.

 

I have as my main scope a 300MHz Tektronix TDS3250 scope, now 13 years old. It 
died recently. Turns out is has a Dallas (Clock / ram) chip with integrated 
battery. The battery died, the Dallas chip is unobtanium, and is very 
efficiently soldered into the board. No parts to be had. I found a chip in 
China, but since it is old stock, I have no idea how long that one will last. 
(I got the old chip out with my Hakko desoldering rig, and put in a socket)

 

There is a lot to be said for the old scopes!

My Tek 2236 is nearly 30 moons old and no longer stays on for more than a few

What do you guys suggest for general use and of course clock fixing?

Re: [neonixie-l] Need advice on a new scope...

[Adrian Godwin]

I went though a series of digital scopes before I found one I was really
happy with. All were second-hand.

I had a 16500A, later upgraded to a 16500B. I didn't ever get the LAN
option. On the positive side, it's a proper logic analyser with loads of
inputs, clock and state triggering :  the mixed-signal scopes don't usually
have enough inputs to deal with an Z80/68000 era bus. But the scope part is
400MS/s, 6 bits and a bit clunky. The whole thing is huge and noisy.

I bought a cheap Owon with a TN screen. It was awful. Got rid of it.
I bought an early Rigol. Didn't like the very small screen. Sold it.

I bought an Agilent DSO7014A then upgraded it for free to MSO7054A spec
(mixed signal, 500MHz, 4GS/s). It's great and even though it's obsolete now
I will be using it for a long time. The 5000 and 6000 series are similar
(see reviews by Mike's Electric Stuff) and can have a VGA screen attached
for a larger display.

I also have a Hantek similar to the one Richard describes ut an MSO. It's
not in the class of the Agilent as you might expect at 1/10 the price, and
the digital inputs in particular are poor (no trigger) but it's useful as a
portable. My feeling is that of the chinese scopes, Siglent and Rigol are
the best of the bunch but I'm going mostly on hearsay - the one I owned is
not representative of current models.

I think it's worth making cheap mistakes  to learn what you want, and worth
spending a lot more if you use a scope every day as I do. And it took me 6
months to properly shift to using the Agilent from an analog Tek so do be
patient and don't assume it will be instantly familiar if you have a long
history with analog scopes.

The earliest ones in this list really just added one-off waveform capture.
But the Agilent tries hard to be 'as good' as an analog scope along with
all the digital bells and whistles. It's not an easy thing to do but
there's a reason the frontrunners eventually stopped making analog scopes
at all. However, the early ones don't match up so although I didn't buy
new, I did learn what would be disappointing and used only as an
alternative.

[martin martin]

Thanks all!
I am going to try to fix the old girl and also explore new scopes.  I have
read good things about Siglent and Hantek also!

Re: [neonixie-l] Need advice on a new scope...

[Richard Scales]

At the risk of being thrown out of the group - for all fixing and related 
activities I got a £140 dual channel 'Hantek' scope from Aliexpress and it 
has been rock solid for the 5 years I've had it.

The current equivalent would be something like 
this:

There have been occasions when I wished for just one more channel but I got 
over it!
