'[OT]: budget oscilloscope?'
2004\07\19@182330 by Michael O'Donnell

Lots of talk about really nice oscilloscopes on the list, but they are all
out of my range.   I'd like to get a very basic scope to use for fairly
simple electronics projects, perhaps something in the ~$100 price (on
eBay)...

Scopes sell for that price, but I'm sure that there were some great scopes
as well as a few dogs built back in the 80s.

Without intending to set off a religious battle, what are some of the
classic scopes that might be going for low prices now?  There seem to be
lots of Tektronix out there, but are other brands (Hitachi?) good?  What
about well-regarded model numbers?  I'd like to have a few models to search
for and then just look until I find a good one.

Any thoughts or considerations would be greatly appreciated.

cheers,
mike

The late model Tek 453's are supposed to be pretty decent scopes. 50MHz,
two-channel, built throughout the 70's. All solid state - no tubes
except the display tube (watch out for some early models - they had
tubes). I just got one off of Ebay, recently calibrated (2001), one
probe, lots of accessories, works fine, decent cosmetic shape, seems to
work fine, for $80. It seems like the 453's come up on Ebay pretty often
for really cheap. Just watch out for dogs/lemons.

TTYL!

I too am after a budget 'scope...

How long do solid state 'scopes tend to hold their calibration? (I know;
leading question). If, say, one was calibrated in the past five years, is
it likely to be okay for hobbyist use?

Tek 465 is excellent.

I have an HP 1220A two channel 20MHz and it works great for me. I paid
about $60 on eBay.

I was a calibration and repair (component level) tech for 20-30 years.
Tektronix for high frequency (>10 Mhz), HP for low frequency (audio,
<10Mhz); are the best.  Tek and HP had better mechanical construction,
better switches, and better triggering circuits.  They tend to stay in
spec unless abused.  Most also have minimal amplitude and timebase
calibrators built in.  Frequency response is more difficult (expensive)
to check/adjust.  Other brands were often unreliable (switches noisy,
triggers difficult to adjust, etc).  For general troubleshooting, 10-20
Mhz is OK.  For digital circuits, 100 Mhz or more; is needed.

It is important to remember; test equipment that cannot be trusted to
give accurate and reliable information, will cost more time and
frustration than not having test equipment at all.

So is its big brother, the Tektronix 466 Analogue Storage Scope.

Later.

I have a 468, which is the digital storage big brother of the 466.  I paid about $150 for mine in mint condition.  Works great for me.  I'm considering getting the new pocket bitscope because I need a logic analyzer, and the price is more attractive than the full blown bitscope.

Regards,
Bob

Is Pocket Bitscope any good? That might be an option for me as a primary
scope/analyzer/function generator....hmmmm...

I'm also thinking of buying a scope. Has anyone got something to say about the Tek 2445B? I found it for 100$US, looks reasonable, but I'm not an expert in scopes.

Thanks,
csb

I was wondering the same thing.  I hear lots of opinions that PC-based
scopes are a wasted of money, but this thing is attractive to me at
least because of the openness of the project.
