A 60 ps TDR wouldn't be terribly hard, either. The worst part
would be
the Windows software.
I didn't go below 200psec and mainly because the medium to be probed
doesn't support any lower. Haven't tried it out in real life yet
because
the boards aren't back but this kind of stuff usually comes out as
simulated, or pretty close.
The thing about doing a TDR is competing with Tek 11801s on ebay. But
there IS a market that I think would work.
I am not so sure about the market. I've helped a lot of start-up
clients
equip their labs initially. Rarely did they ever truly need even as
much
as a 200MHz BW scope. Most of the time a 50-100MHz budget deal was all
it took.
There is a market. I just haven't had time to work on it.
For TDR (which is fairly easy) there are markets but I really don't see
one for regular sampling scopes like what the Tek 11801 was. Else they
wouldn't pawn them off for around $1k like here:
http://www.ebay.com/itm/Tektronix-11801B-Digital-Sampling-Oscilloscope-with-Module-SD-26-/191018227396?pt=BI_Oscilloscopes&hash=item2c7992d6c4
Because not all companies buy on eBay? Because it's just as much work
to buy a $30K scope as it is a $300 scope (well, the only TDR I've
seen recently is more like $100K)? Because the keepers of the capital
equipment inventory lists, instrumentation, and calibration will never
sign off on such things?
Even for engineering use?
Yes. We don't do manufacturing (here). Processes are processes.
ISO9K, and all that rot.
Nah.

Quote "Many companies don't calibrate rarely used engineering/service
equipment because of the cost. As long as the equipment is not used for
validation and the equipment is controlled, it is OK".
*THEY* don't. So?
I went through ISO training sessions galore. It means it's legit as long
as you have proper procedures set up.
I've done more than my share of ISO training (was the first one to go
through the full-banana ISO audit at IBM P'ok). The issue is the
process. If the process says that thou shalt shit in your hat...
Think about it: Who writes the procedure for the process?
That doesn't matter, at all. ...
Sure it does.
... The fact is that the procedure is there
and it's "worked" for a couple of decades ...
It has most likely resulted in lots of wasted Dollars.
... - long before I showed up
(and when it was a manufacturing location with *very* little
engineering). I certainly wouldn't have written the procedure.
For some gear you even have to because there are no calibration services
for those or support has been discontinued. Just ran into yet another
case of that this morning.
Can't have that gear, obviously.
Sure. I'll just have to see if I can return this machine (or donate it)
and buy another one of same type that has the feature we need enabled.
The problem was that they threw out all activation codes for firmware
options. I had my credit card ready, they could have made a nice sale
right there, with a bare minimum of investment on their part (about 60
seconds of their time). Beats me why large corporations shoot themselves
in the foot so often.
Because those who profit aren't those who do the work. There is good
reason for bonuses based on the bottom line. The problem is that
they're so often bogus in a large corporation.
We were always nicely rewarded for achieving good results with very
modest engineering budgets. That was made possible, among other things,
by resorting to vintage equipment where that made sense. And it made
sense a lot of times.
