A saint once sang a song for me, like this: Leaving this world when you go away Nobody will accompany you on that day.

He also mentioned you come in this world empty handed and you leave this world empty handed.

My view on this, as a 'technical' person is: Your efficiency in percent = 100 X (days_happy / days_lived). Or in Larkin speak: 100 x (femto_seconds_happy / femto_seconds_lived).

tick tick tick tick no storage will keep it.

I have had several articles published in at least five different electronic magazines around the world over the years, how do you stand up ?

Is that what you have done ?

I don't know who you think said that DSOs have no purpose, or are you into strawmen today?

that?

Before you show what an asshole you are, again, do note the quotes around "before".

No articles. I've designed over a thousand circuit boards, net sales around $200e6 so far.

Aren't you the guy who claims that gravity travels faster than light?

Among other things, yes.

Takes a bit more effort to write a good article, but you are probably up to it. Perhaps you should try, nobody reads your name on a pcb.

No, you and others seem to be confusing me with someone else.

I derive deep satisfaction from seeing my name on purchase orders and checks.

Well, we aren't confusing you with someone who talks about electronics.

John

Me, neither.

I always preferred the HP storage tubes over the Tek ones.

They all appear to use scan converter tubes, effectively a small CRT coupled to a CCD with LCD raster display.

If they're anything like the 400MHz, LeCroy-badged one that I had on demo for a few weeks, some years ago, the trace will be unacceptably thick. We sent that one back.

I'd happily pay $28K plus for something the ilk of a 7104.

The original Tek storage scopes didn't have a grating. They used secondary emission off the surface of the phosphor, a trick that had been around for a while [1]. They had a light trace on a paler illuminated bachground, the illumination coming from the flood gun.

Some of the later Tek scopes used the HP-style mesh storage effect. They looked great compared to the older washed-out secondary-emission things, bright trace on black background, nice variable persistance, good tube life, but the writing rate wasn't as good.

I think Tek and HP had a blanket cross-license on oscilloscope technology. The story is in Lee's book on the history of Tek, as I recall. There was an argument over whether some license fee would be donated to the Stanford or Portland football teams.

[1] I think it was Whirlwind that used secondary-emission CRTs as RAM.

7103s and 7104s appear on ebay for around the cost of shipping. Our 7104 is the only analog scope I ever use.
