Tektronix 2445 Oscilloscope

Yes.

It's the best portable analog scope(the 2445/65 series) TEK ever made,BUT; it's out of production,ICs and many other parts not available except by cannabalizing other 2400 scopes.Most of the major ICs were TEK-made,same for attenuator substrates and some passive components.

Tek no longer makes or stocks any of them.

So no way of repairing it should it fail. I am buying from ebay. Cheers Ray

please?

You might want to pick up another one (non-op) to cannibalize.

Yes,I just wantedmake sure that you knew the downside to buying a TEK 2400 scope,not to turn you off from buying one. Some folks may not have the desire to repair by cannabalizing other scopes,or not have the repair skills and equipment to recal them after the repair.

I understand what you are saying Jim and appreciate your advise. I am not into repairing or fiddling with scopes, do not really understand all the functions some of these scopes have. I am looking at a Agilent 54622D mixed signal oscilloscope but no sure if I would use all it's functions. The data side looks nice as I am playing with PIC microcontrollers.

Even second hand these things are expensive so want one that will last a bit and have a chance of being repaired. But do these sort of things 'break'? Trying to get the best for my money but its giving me a bit of an head ache.

Regards Ray

PS: also looking at a Schlumberger 5224 oscilloscope.

PPS and an HP Digitizing Oscilloscope 54111D.

hi,

seems russ is looking for al the oldtimers to get a scope.

So to speak simple: If you buy used & old equipment, it CAN always fail and be hard to get repaired. But of course it is NOT PREDICTED that it fails.

So go for the scope you like and can afford. with most of the premier brands (Tek, HP, LeCroy) you are well fed. Of course, you have to pay for the quality.

just my 2cts., hth

In response to what tekamn posted in news: snipped-for-privacy@g43g2000cwa.googlegroups.com:

I bought a 15-year-old Tektronix 545 in 1982, it's still working. Pushes out 1/2kW to warm the workshop, too!

JUNK is stuff that you keep for 20 years,
then throw away a week before you need it.

Cheers all.

My use would be occasional so theory being it should last me what ever I get.

Also I intend to use with spectrum analyser adaptor.

Still looking lots to choose from.

Regards Ray

First, decide whether you want an analog or digital 'scope. They are

*not* the same animal, and the things you can do with one, you cannot necessarily do with the other. If you are used to analog instruments, you'll probably find a digital 'scope has behavior that you will not find intuitive, perhaps even find irritating.

I *could* go on to say that if you've only known digitizing 'scopes, you'll not know any better ;-)

Jim's right, the 24XX series are among the best analog 'scopes ever made.

I use a couple of 2467Bs, in addition to various mainframe instruments. My only reservation is that some of the controls operate through DACs, and have a bit of a lag on things like brightness and readout intensity. Damn nice instruments.

I am looking at a Tek TDS 1012 Digital scope, also.

Hi,

Is it easy to say which is best analog or digital?

My main use would be checking PIC microcontroller circuits and with an adaptor RF spectrums. These may be to very different applications or would one suit both. I am only a hobbyist so I would like the best I can afford to suit both worlds. However, I like to get as many functions and features I can afford, this way I may expand my use and hobby.

cheers.

Well, after reading all these posts:

You should go for a Tektronix 453. This covers well your needs & your budget.

just my 2 cts, hth

Hi, will look it up. Cheers.

If you're doing any digital work at all, and/or you don't want to maintain your own scope, stick with that TDS 1012.

The 453s are all getting long in the tooth, and while they are among the best portable analog scopes ever made, you're likely to be better off with a digital scope of some sort.
