True analog scopes
« on: December 12, 2022, 08:49:59 pm »
Do true analog scopes still get produced? is there a market for them or specialized applications for which a digital scops is not suitable? I suppose too that a true analog scope couldn't really use a digital display unless the resolution of the screen was huge and that in turn implies there'd need to be some kind of A/D conversion involved, so it wouldn't be true analog scope...

B&K still lists one.
Probably a rebrand like many of their products.

If you must there's 14 of these outdated things here:

Well, there's zero quantization noise, so I was wandering if some applications find that important?

Myself, I prefer analog stuff. Simple, easy to use.
I do have a digital frequency generator that is a pita to use. Wading through menus and pushing six different buttons to get something to do what I want is not my idea of fun

have Tektronix scopes since 1970, in Paris Hameg

Paid €5, 25 in Paris at fleas

Look for local Ham radio Fleas, or estate sales, or silent key.

They are easy to fix and made in USA or EU not China

They are, but not for the amateur.

Few even have meters that are capable of measuring EHT and there is always the requirement for a second scope just to fix your main scope.
Stuff that, been there done that and it robbed so much of my hobby time instead of getting on with the enjoyment of it.
Now I sell reliable instruments to those that want to pursue their hobby with a minimum of headaches.
You from another age would do well to take a modern instrument under your wing and actually realise how far the Chinese have come.

Well I'm going to try a Siglent you might be interested to know - a Siglent SDS1104X-U. Let's see what the experience brings. Will let you know.  :)

Please do.
Those are an entry level 4ch with just a basic feature set and I thought we'd sell more of them than we do however the 4ch X-E are still #1 for us as buyers seem happier to spend a little more for the somewhat better feature set.
YMMV

We have used many fine digital scopes available from USA, EU, Japan,
tektronix, HP, Yokogawa, Le Roy.

The OP asked about analog scopes.

I am unaware of any Chinese made CRT scopes.

Ask the Chinese if the Taiwanese CRO's I linked earlier are not made in China.  >:D

Maybe you need ask Mr Google:

Says he whom owns a modern DSO to use as a sanity check of his ancient CRO's.  :P

How are you buddy, is that probe I sent you still working OK on that mini Tek you have ?

Of course I embrace new tech where it makes sense. But don't discount the old stuff.  ;D

That probe works a treat. Thanks.  :-+

For a brief, shining moment, when the $A was above parity with the $US, a new DSO was affordable for those of us on a restricted budget, but these days, we are confronted with things like a SDS-1102DL+ for $A598.00 plus GST.

or a DS1052E for $A429.00 plus GST. at EMONA

Even a Digitech/El Crappo from Jaycar is $A549.00 GST included.
They do have a 25MHz toy for a more affordable $A239.20 GST incl.

On ebay there are some Hantek, Owon, & FNIRSI things at around $A300.00, but I'm dubious about them.
Rigols & Siglents are not much different than buying locally.

Even ancient TDS210s & 220s are around $A300.00 & upwards.

I guess I will have to fix my Tek 7613!

Wow, Wavecom are really taking the piss !  :P
$100 + GST cheaper for the same 100 MHz 2ch model at the Oz master importers Trio:

oo weally? can you differentiate white noise vs black noise? analog vs digital noise? english noise vs asia noise? have you heard about sinc(x)?

There's 12 bit DSO's available too.
Guess which kicks arse.  ;)

There are 14bit DSOs available too, but not from your supplier.

One also includes a spectrum analyser (where the extra resolution is visible), network analyser, impedance analyser, bode plots, AWG, pattern generator, logic analyser, protocol analyser, curve tracer. Plus you can create extra instruments via scripting.

Is it general purpose? Yes in some ways, no in others. Specify the job and use cases, then choose the tool.
There are lies, damned lies, statistics - and ADC/DAC specs.

Yes, really. Didn't you know? if you convert an analog voltage to a digital representation of that voltage, you'll introduce quantization noise. If you actually watch that video, you'll see he's not talking about quantization noise.
