Turn your Rigol DS1052E Oscilloscope into a 100MHz DS1102E

[Nico Coesel]

The Tek 2465 has not been made for many years, the only ones available=20
are used. And guess what, they are a damn sight less than $12000. My=20
current use is more like (kind of well off) expert hobbyist. Guess=20
which one fits my needs best.

A second hand SS-7847A (Lecroy LA314H) is likely to be newer, better
and cheaper than a Tek 2465. Just check Ebay.

Do you know anything about electronics?

Yes i do, it was my first career choice, then I realized the big money
was not going to come your way if you called yourself an engineer.
Sad but true...

 

[fritz]

You can continue playing with your dick as well, I don't give a shit what
wankers like
you want to call me. You might choose to respond in an intelligent manner
one day.

 

[fritz]

So what do you call yourself now?

Financial Controller,
Try it, you will make a lot more bucks...

 

[fritz]

So, are you enjoying the big money?

John

Yes, I sold my soul but.

Name calling. In capital letters to boot!

I call a spade a fucking shovel, sorry if you are such a wimp and
have never met a real Aussie.

Yeah, we have. Phyllis has been around here for years. Yes, there is a
similarity. He's an asshole too but actually knows something.

I see your argument style.

It's simple - rattle the cage when it is necessary to point out that you are
unable to respond to the points raised.
You have not defended censorship at all, was that your intention ?

We've proven that you're a liar. That's all that matters, here.

I still cannot figure out if DC is that dense or if he is just really
into trolling.

He wouldn't constantly start the same thread if he weren't a troll. He would
design some electronics but he's too dense.

 

[Rich Grise]

Yeah, imagine being a lawyer or a banker and dying rich. What's the
point?

Yeah - he who dies with the most toys wins, right? ;-)

Cheers!
Rich

No, you are wrong again. I have never heard of DimBulb.

Funny, you're dim enough.

Yes my ignorant friend, but you are seeking to distort the right to freedom
of information
with the right to privacy.

You believe there is a right to publish *anything*, even that which is
private. You've said so.

Hear, hear!

Agreed. There are very few things I can think of where you can make
decent money and stay creative for a decent percentage of your time.
I can not imagine being a doctor and seeing 20 people a day - yuk.

I was thinking about that very thing the last time I sat in an "immediate
care" (a.k.a. "Doc in a Box") facility waiting to see a doctor. The poor
slobs must see forty or fifty people a day, every day. Yuck! A surgeon seems
more challenging, but still on the order of a technician.

Delay lines can't store milliseconds of pre-trigger data. The best
they do is let you see a few ns of pre-trigger waveform.

John

You clearly have forgotten how delayed sweep works. The sweep is not
even on the same trigger cycle. Say alternate trace, just like is
typical for multichannel analog scopes (dual gun scopes excepted).

 

[JosephKK]

It's hard to store much information in an electromagnetic delay line.
The losses kill you.

It would be an interesting calculation to see how many bits you could
store in any preferred length of, say, RG58.

Fiber is a different story. You can stuff gigabits per second into a
hundred kilometers of single-mode fiber and recover it perfectly.

Really? How much does it cost to do that? If you could back off to say
20 kilometers i would not have much reason to find fault. Fiber still
does have attenuation and EDFA can only do so much.

But RAM is a more sensible way to store information.

Sometimes at least, depends on how much and how fast it is coming in
or going out.

[fritz]

Yeah, we have. Phyllis has been around here for years. Yes, there is a

We ???
Are you in some kind of circle-jerk-off group ? Looks like it...

 

[fritz]

If you said anything sensible about electronics, properly bottom
posted, I would
John

I have had several articles published in at least five different electronic
magazines around the world over the years, how do you stand up ?

 

[fritz]

You can make pretty-big money designing electronics, and have fun all
the while.

But the real secret to success and happiness is to marry a beautiful
woman who has a good job.

John

Is that what you have done ?

 

[[email protected]]

We ???

Yes. There are more than two, hence "we". You can thank me for your English
lesson for today.

Are you in some kind of circle-jerk-off group ? Looks like it...

No, I don't belong to your club. You're not my type.

One case where a DSO comes in handy:
http://myweb.msoe.edu/williamstm/Images/Induction1203.jpg
something was clicking erratically, possibly a gate drive, I'm guessing it
stuck on for at most a few cycles. Bad sign, and the clicking means
magnetics, or worse yet, sheer amperes, are causing audible movement of
wires or capacitors. You can see a number of cycles on this exposure, where
current (bottom, triggered) is going wild, and you can see some voltage
steps where the coupling capacitor got charged by this action. But without
a pretrigger on the order of microseconds, I can't very well see when it's
misbehaving.

I don't know who you think said that DSOs have no purpose, or are you into
strawmen today?

Please explain how a delaying timebase could allow one to see events before (and
I mean much more than a delay line's worth of "before") the trigger event if the
trigger event is a one-shot event; no periodic waveforms involved.

Before you show what an asshole you are, again, do note the quotes around
"before".

 

[fritz]

No articles. I've designed over a thousand circuit boards, net sales
around $200e6 so far.

Takes a bit more effort to write a good article, but you are probably
up to it. Perhaps you should try, nobody reads your name on a pcb.

Aren't you the guy who claims that gravity travels faster than light?

John

No, you and others seem to be confusing me with someone else.
