Tom,
I think one reason you might not appreciate Craig's comment and position is
twofold. First, is that I would guess that you're reading the posts via
email and so, I agree, it is very easy to delete, but I think we've all
been at the spot where we open an email thinking it is about one thing, and
it turns out to be about something different. The extreme of that is spam
advertising. Opening an email thinking it's about 7000 series stuff only to
find it doesn't have anything to do with the stated subject except in a
vague or oblique way, can be just as frustrating and would also fit the
definition of spam from a content point of view.

Second is that when searching on line and hoping to find an answer,
particularly with detail or troubleshooting, I personally find it more
pleasing to not have a lot of extraneous stuff in a topic/subject thread.
While it seems impossible to achieve these days, it's a laudable, and
apparently achievable goal.

Having said that, When I opened the thread, I didn't expect a 7000 only
post. In fact, the post pretty much fit what I expected, a story. In fact
the subject like practically advertised that there would be a story. I did
like the story as well :-) After all, it told of reasons why the 7000
series is useful and part of that is an incredibly necessary explanation of
how and why the writer came to that conclusion so that as readers we might
consider whether we agree with his premise that "7000 still hard to beat".
He seemed to tell a story that made that point well.

So, in my estimation of things, Craig's original premise (that the OP's
"subject" and contents were inconsistent and not appropriately descriptive)
wasn't reasonable, but his comments about keeping reply posts on topic or
at least highly pertinent to the original topic was (again IMHO) a good and
important point we should all endeavor to subscribe to.

Hi Craig-

I must be missing something....

If I click on a thread and see that it's veered off topic so that it's no
longer of interest to me, it only takes oh maybe 3 - 5 seconds to click on
another thread. That doesn't seem like a big deal to me, but am I missing
something? I genuinely don't understand the problem!

Have a great evening!

Frustratingly this happens all the time, and renders it difficult to

There is one list I'm a long standing member of
( ) where
if a thread strays off topic the mods simply delete the straying posts,

often

within minutes. And
don't even tell you if and why your post has vanished.

I'm not remotely suggesting that we go down that route - just a little

more

discipline in (a) using
an informative title for the thread and (b) if the thread changes to a
different topic to change the
working title to reflect that.

We agree about the politics entirely ;-)

Craig,

You are out of line here. You are my friend, but you are
wrong.

Peter opened this thread describing how his go to 2465B
fell short of his needs, forcing him to resort to a
combination of 7A22 and 7000 series scope to make his
measurement.

That was an obvious opening for both 2465B fans, and
7000 series fans to discuss the topic.

To add fuel to this fire, I calibrate lots of 2465 family
scopes, for group members, but my go to scope is a 7854
for the same reason that Peter went to his 7103/7A22 to
solve his difficult task.

I keep my 7854 stuffed with an assortment of plugins that
meet my daily needs in a way I just can't with the highly
capable, portable, but ultimately limited 2465B.

Discussions on this group are never fixed and ridged they
wiggle and squirm their way into different discussions...

But excepting for your tirade, this discussion has stuck
to its original course. It started as a discussion of
2465B's vs 7000 series versatility, and so it has remained.

Be glad that we haven't veered into politics.

-Chuck Harris

There is nothing more frustrating than keeping a message title and

digressing onto another topic.

Well that is a little rude Craig. The OP clearly states that a

2465B is

his main scope and he

only
pulled
out a R7103 and put in a 7A22 for greater sensitivity and

differential

input. My simple question

was
asking if there was an active probe with diff inputs that could

increase

his main scope, the

2465B.

OK, but come back if you miss the conversation.

Hi all



I've been thinking about this for quite a while. But I think after 18 years on Tekscopes it is
finally time to sign off. In part it is because I think I have said all there is that I can possibly
say on Tekscopes, and in part because I just figured out that I have posted over 4,600 times - an
exceptionally depressing number, even more so when it represents 14% of all posts to Tekscopes ever.
That is one in every seven posts, heaven help us all, that I reckon to be over 800 hours of typing,
not counting the thinking time.



So to the many people who are on this list who have helped me to figure out problems in my stable of
Tektronix gear - my heartfelt thanks. There have been notable assistance above and beyond the call -
as an example, while describing a particular fault in my 7854, one of the list members disconnected
the sampling bridge in his own unit to mimic the fault! And yes, my vertical sampling bridge was
indeed toast. You have all been an inspiration, and I hope that some of you think of me as a friend.
I also hope that over the years I have been able to contribute something to others.



Anyhow - cheers all



Signing off

The old silver mica caps were used in lots of antique AM broadcast radios (1930s -1960s),
particularly in
the IF stages. They were known to cause a phenomenon called "thunderstorming", which, even
when receiving a strong station, caused a random loud static that sounded exactly like a nearby
thunderstorm. This was caused by the silver deposits on the surfaces of the mica layers actually
migrating toward the edges of the mica slabs. The high voltages used in those old tube radios drew
the silver atoms toward the edges of the mica, and when enough silver migrated to the edges, there
was enough current leakage in the capacitor to cause the "static" noise.
Of course, the only solution was to replace the old micas with new ones and retune the IF stages.

I need to get a 2764DC EPROM copied to a text file in (preferably) BIN
Format.
It contains the Version 2.0 executable code for the 7000 series 021-0374-00
GPIB Decoder Plugin.
These GPIB Decoder plugins are extremely rare and it would be valuable to
have a copy of this version of the EPROM software for our archives.
They are used to control the 7xxxP programmable plugins in the 7912AD,
7912HB, and 7854.
Pictures of this plugin can be seen on TekWiki at:

The astounding 7104 is capable of displaying X/Y waveforms to over 1
GHz since the 3dB bandwidth of the internal 7104 horizontal amplifier is >400MHz.

Here's the thing Chuck - if the topic was called something like "2465B and 7000 series - a comparison"
