Rigol DS 1052E CRO

"JERD"

But you cannot call it a CRO.

Cos it ain't one.

Yep, that's the guy we bought from. No problems with him whatsoever. Fast ship with tracking, original box and accesories etc, even an aussie power cord.

For the price, it exceeded my expectations.

None. Nor would you expect to, Rigol have a very good rep.

Dave.

Thanks for that feedback.

I am from the old school and 'bad habbits die hard' ( Nearly 70) as Phil reminded me, its not a CRO!

JERD

Indeed. But you still wouldn't be laughed out of the lab by asking for the Rigol CRO!

Speaking of the term CRO, does anyone know the history of the acronym CRO? It's pretty self explanatory of course, but haven't oscilloscopes always used cathode ray tubes for the display? If so it makes the "CR" part very much redundant I'd think, and I'm now rather curious as to how and where the term CRO came into general use. i.e. Did some of the early manufacturers market them as a "Cathode Ray Oscilloscope" or just plain "Oscilloscope"? I know that CRO is very much an Aussie favoured term, with the yanks and many others prefering just "scope" as the abbreviated name. Would be interesting to know the history behind this if anyone has any ideas?

Dave (who lags behind JERD by a good 30 years or so!)

Maybe to distinguish them from the old oscillographs that were used in the power industry to capture transients. They used fast reponse styluses with a voltage on them, writing on electrostatically sensitive paper that you then (IIRC) had to develop.

Indeed the yanks have interesting speak. Scope is certainly one. If you asked someone to grab a scope here, you'd end up with a soldering iron! (Are they still made?) Say the word CRO to a yank and they look at you strange!

Another is Zee-80 as opposed to Zed-80

Sorry, I'm also (sort of) showing my age!

Dunno, I've always called a CRO a scope. Scope soldering irons were only ever good for lighting cigarettes.

Yankspeak, in my experience, mainly consists of dropping letters from words like solder becomes sodder, error becomes err etc.

Very happy with it. Fast delivery (about a week) direct from China, all the accessories, ready to go.

There was only one strange problem, was using it while developing software on a microcontroller with it,

At a certain sweep frequency, it refused to show a square wave that was actually there !

(note, circuit worked, and waveform could be seen on my old Tek Anlaog CRO.)

If you changed the sweep frequency 1 step up or down, it appeared perfectly.

Unfortunately I can't remember the details of the frequency etc.

Honest, hard working and never tell lies.

Tip; make sure it doesn't come by DHL. My last package from china sat in Sydney for five days.

This was OK, was EMS - came through the post office.

I get DHL from China regularly, no problems at all.

Dave.

That was what had me head scratching this time. Last time was Aust Post.
