Tektronix 465m vs 465

Does anyone know what the differences are between these two models of scopes (if any)?

if memory serves, the M is a higher BW unit.

no,the 465M was a "ruggedized" scope,closer to a 455A2B2 than a regular

465;not ANYthing like a 465 WRT circuitry.No common parts. (dunno about the CRT) They both were 100Mhz scopes.

And it really wasn't more rugged,IMO. I'd rather have a 465 than a 465M.

465M is the Military version. It's functionally about the same, but it looks different.

CRT has a different part number but it's compatible. I have a 465M CRT in my

465B and it works fine.

as are all scopes.... ;-)

electrically,it's totally different;the 465M has one hybrid (TEK-made)IC that is the entire vertical preamp. the 465 pre-amp is discrete.

I also disliked the flex of the 465M plastic case.

Touché :)

What I was getting at is the performance specs are about the same. I wasn't aware of the hybrid chips, that's as good a reason as any to avoid it. I hate scrapping an otherwise fine piece of equipment because of bad custom parts made of unobtanium.

The 465 still has TEK-made ICs in it;the 155-0049-0x sweep logic IC,a couple of trigger amp ICs(155-0032-xx)and some have a vertical output amp IC. IIRC,the 465 was the top selling scope of all time.

But there are SO many other TEK scopes that use those same ICs,they are still obtainable.
