Re: TDS360 -- any good?


"Sergey Kubushin

This is all for my hobby that is mostly tube audio stuff. And I have my
reasons to suspect that my wife would call those guys with long-sleeved
shirts (which usualy weared with skeeves tied at one's back) handy if I
start fitting a camera to my scope :))


** How silly.

A regular 35mm film camera can be used as a scope camera provided you
have a
lens fitted ( or close up rings) that will allow the scope's screen to
fill the frame. A 50mm or 100 mm macro lens is perfect - since the
in-focus field is a flat plane.

All you need is the camera mounted on tripod, lined up square on the
scope
with a cable release for the shutter - use some 400 ASA colour film
and
have the room lights very dim. The lens should be set wide open ( F 2.8
or
F4) to allow even single shot events to be captured.

The local fast processing lab will have your photos ready in a hour or
so.

Yep, that's not rocket science. But there is one big BUT -- why bother?


** You will get a top quality, *real* screen image.

Not the grainy, dotty abortion that comes from a typical DSO.



I AM
old-fashioned too, I do believe in matches and kerosene and do not believe
in electricity, I do listen to vinyl records that I have several
thousands,
I do watch LDs that I still have almost a thousand, but I'm not THAT
old-fashioned :))


** What you really are is a old fashioned, arrogant pig.


I do NOT make oscilloscope photos for living, I'm just a unix kernel
developer doing tube audio stuff for mere fun of of it... And man, I DO
know
how to talk to all those funny GPIB toys from Linux... So I'd better buy a
digital scope instead of 35-mm camera, tripod, fitted lens etc. And I
would
probably feel much better pushing a button in Linux than making all those
awkward moves and pushups around the scope with a camera... And the best
part of it is that a screenshot would go right in my occasional article I
need it for without a need to pull my lower part outta a chair, bring it
to
a lab and then scan the photos...


** Shame it will have no detail, look fake and crappy.


Just FYI: I DO know what camera is.


** But you have neve done scope screen shots like I have.

Plus the info is on a public forum for ALL to see.

Not just ONE arrogant, mad Ruskie ***.



And I did own not just a cheap 35-mm toy
but a genuine Hasselblad.


** *** off.


And I did NOT ask anybody for a "How to make a
photo of an oscilloscope screen for dummies", I asked if Tektronix TDS360
is
any good or crap...


** Been answered in other posts.

Try reading them, and cut out the SMARTARSE CRAP !
