A guy clearing out his deceased father-in-law's basement let me have an HP
1722A oscilloscope. It powers up, and responds to signals. I haven't
tested all the functions, but the basic stuff works. I'm thinking of
selling it. How much is a working 1722A worth?

Below is a link to a 1974 HP Journal that will give you the skinny on
the 1722A's far out capabilities. Catch you on the flip side.

I still have two functional 1725As. The problem is those old scopes have
hybrids in them. You need a spare scope to keep them going.

Actually I bought one working 1725A years ago. I found a cheap junker
for parts. My junker ended up supplying parts for someone elses 1725A.
[Gratis on my part because I'm just sooo nice.] So when the person
wanted to get rid of that 1725, I figured I better buy it since it had
all my parts in it anyway. Plus having a spare functional 1725A kept the
other scope scared shitless of being a parts scope, and then it never quit.

But I think I paid $100 15 years ago. Today you would be far better off
just putting the money into a Rigol than getting a 70's era HP scope.

I've turned down working Tek 7904s with all the plugins for $150. And
that was with the cart included. [You need the cart for those boat
anchors.]


But the 1722 is like the 1725 in that they are reasonably high
bandwidth. Sometimes it is nice to have an analog scope as a sanity check.

The delayed sweep is kind of funky on those old HP scopes. They weren't
particularly popular when they were new. The trigger was much maligned,
but I never found it to be as horrible as some stated.

High praise indeed!
Well, the Tek scopes of that era were a bit better on the trigger. But
the talk around the water cooler was the HP scopes didn't work at all,
and that wasn't the case.

The Tek 465 was basically the workhorse at the time. Or at least the 400
series. I may not have the exact timeline, but the 465 was a late 70's
scope.

I remember shirts like that.

1974 dress code. I also had white bellbottoms, wide belt with hippie engraving, and platform shoes.

Early 70s I think -- of course, they would've had more market share and
better prices by the latter end. My 475 for instance is dated 1973 or so
(465 of course predates it by a couple).

The last decent HP scope was the 130C.

To HP, "trigger" was a horse.

It has been downhill forever after.
