Free Tektronix 454 Scope (small fault) Manchester UK

[JimFranklin]

I have a Tektronix 454 Scope (dual trace) with a small fault on the timebase,
(see attached drawing of a squarewave)

It is useable for most tasks, but this is really annoying to see.

It is too good to just throw away, so anyone in or around Manchester, England
(Bolton/Wigan/Altrincham) who wants it just get in touch and I'll arrange to meet you
somewhere with it. (it's free)

Have you tried calibrating the scope probe?

oscilloscope Tutorials.
The image you're showing looks like classic overcompensation.

I had tried compensating the scope to no effect, but not one to ignore suggestions, I have just fired it up again and I have a different fault...

With all inputs set to GND i get the attached trace.

As I have a replacement scope (a tektronix 2445 4 channel 150MHz scope) I just want to give this a new home, if anyone wants it.

Hi Jim,

Thanks for your generous offer to the forum.

I might be interested in your offer, I have sent you a private message.

I've already got a couple of scopes, but if you're binning it I'd take it off your hands - I couldn't bear to see it binned.

But I'd rather you find a more deserving home - but I'm here as 'last resort'.

 

[JimFranklin]

I have sent a PM back to Leftfield as he answered first,
and I will let the Forum know what happens.

Jim,

I'd also like third dibs on the 'scope please, if Lefty or Nigel end up not having it.

Cheers.

P.S. PM sent.

Jim,

Not third, second - I only threw my name in the hat as a 'last resort' because I couldn't bear to see it binned
