Then why did they release it?
Mine does crocheting a lot, but only if it is for charity. I thought that crocheting and knitting are almost the same thing but was taught otherwise. I share your hobbies except for writing software, that was never much fun for me.
So they opened a new business at the same location? Hopefully it'll do better than the old one. Now that Hameg is sold to Rohde&Schwarz there needs to be someone new who starts measurement tools in Germany.

Because it compiled. Writing code that compiles, takes 50%, writing code that works somehow takes 100%, making code that handles errors takes
150% and making fine code, that does all the before and that looks good, takes 200% of the time, you are paid for. Then you start writing the documentation ;-)...
Writing software means no burned finger tips, no ringing in the ears caused by a big capacitor, but you don't know what is really happening and it may cause mental diseases.

Not simple. I am not surprised, that the chinese are not stupid and will be on "our" level soon. Remember Japan, Korea, Taiwan...

This is quite interesting. An oscilloscope for which you can hack your own firmware... Except for using 4 ADCs per channel the concept of the design isn't bad.

Regierungsfeindlich? Das tut mir gern. ;)
My production of German stinks. I just read it with some modest understanding. So actually part of the reason is to get idioms and common preferences in speaking, too.
Hehe! ;) Natürlich.

The actual word(s) break out as Spiel (play) and wert (value or worth) and it made me think of something more gaming-like, such as "replay value" than "fun factor." But fun factor is much better. Would Spielwert also be used for the meaning of "replay value" in video games, for example? Or is there another term for that?
Jon
That's a major problem, writing documentation after the fact. I never do that. When a client wants a new design the first thing I open is the word processor. Always.

My DSO was engineered in Taiwan. And it's pretty darn good. Even speaks German if you want it to :-)

I've been away from Germany for too long but I believe "Spielwert" always had a meaning close to what "Fahrvergnuegen" is in our Volkswagen ads over here. I've never seen that word on a video game or arcade machine. "Spiel" on those machines means game, as in how many games you have left after inserting x amount of cash into the machine. "Freispiele" on a slot machine or pinball machine is the number of games (or pulls) you didn't pay for but won during a run.
Mostly "Spielwert" is (or at least was) used if something had the potential of being entertaining but not necessarily of being all that useful. Like that midlife-crisis sports car purchase :-)

Have you ever thought what it means in terms of cost when you go from four 250MHz/8bit ADCs to sixteen of them just to have full bore in 4ch mode? It's like saying that I want my car to race up that steep hill at
100km/h even when it tows the big trailer. Sure, you can get that, if you buy a Mercedes Benz S560. But does that make sense?-- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam. Use another domain or send PM.
Ah. Do NordDeutsch carry a stronger negative judgment about Spielwert als südDeutsch?

The "Russian Group" is using them as a cheap training platform for FPGA programming ;-)
They are trying different approaches to make a good DSO on this platform. But as they have a much longer way to go...

On a sunny day (Thu, 09 Jul 2009 22:30:26 GMT) it happened snipped-for-privacy@puntnl.niks (Nico Coesel) wrote in :
I think it is VERY bad. Look at the diagram of the channel amplifiers. All opamps. You may as well replace that by triangles with NOISE written in it. And that is most likely why the thing has 4 bits noise of the 8 bits ADC. I know this will piss of those who worked hard to improve that firmware ;-) But get real, long long time ago, tens of years, somebody at Tek published (long before there was anything like Internet or 'online') the diagram of a
*300MHz* analog Y amp for a CRT scope in a Dutch electronics magazine. It used discretes, BFY90, and could output tens of volts to the CRT. And of course it was not noisy. I build it, and used an East German CRT with similar bandwidth, that was my third scope... Many many years later I met the person who published that at Tek, he told me Tek was not too happy with him publishing that diagram, but in my view it sure made a good commercial for their scopes :-) So, anyways, with a couple of discretes you can make a much better amp in my opinion, probably cheaper too Why the guy used op-amps is perhaps the same reason the software guy used C++? No clue, and opamps are so easy???? Well now you can flame if you want. Although I am not sure that design will burn. LOL hehe
I figured a literal translation wouldn't cut it, already. So what work is used, then, for the case describing a game that retains its Spielwert very well even after playing it a few times? Or is it just that it is explained with more than one word?
Thanks, Jon
Sorry, I meant 'so what _word_..."
Jon
What's the ADC's input range? If it's something like 1V, that's 3.9mV/bit. which in a bandwidth of 100MHz 390nV/sqrt(Hz) -- a VERY noisy amplifier.
In other words... I do think one *could* readily design a 100MHz front-end with an op-amp these days and still achieve 8 bit resolution. Whether or not they did is another question, of course...
Probably so, but they probably figured it was already cheap enough and didn't have the skills to implement a discrete design.
Pretty much anything you get from Tek or Agilent these days is going to have plenty of C or C++ (or even .Net!) in it these days.

Sure, you've got the whole THS-series from Texas to do it with. Can be had for around five bucks a pop and great noise performance. I did it even in the 80's. Ok, the Harris amps back then were power-hungry and expensive but then, thanks to VCRs becoming ubiquitous, there was (and still is) this gem for under a buck:
Very common these days :-(
My horror was a scope with a Windows-OS on there. Could have been LeCroy, don't remember, because I instantly told the client we'd need a "real" scope. This often leads to a trip into their basements where there is a pile of Tektronix mainframes and stuff that nobody has used in years. Usually they still work just fine.

Yep, a THS4031 makes a pretty decent RF amplifier if you can tolerate the ~10dB noise figure.
It might be a good interview technique to take a potential employee past a bunch of that stuff and see whether or not his eyes light up appropriately when show them a 2465b. :-)
I like the THS4021 better, it's faster. The noise should be ok for a scope. For really low noise measurements I use a couple of HP lab amplifiers up front anyhow.
Oh yeah! One of the best every-day scopes ever built.
