Re: Tektronix 570 Vacuum Tube Curve Tracer on eBay


SMU is source measure unit. From the KB i saw from Keithley there is a way to do curve tracing with the 2461 and the 2471. It requires 2 units at $9,600 each an interconnecting cable cat 5 on each out to a computer which has the Keithley lab suite software. I think the setup is one SMU for collector voltage and the other controls base current. The units sweep some set points then the software plots and excel style graph from the measured points. There was a KB that Keithley put out on how to set everything up I will see if i can dig it up.

Is there a modern version of these curve tracers? From what I have seen
the 300 series seems to be about the top end. I know you can get the
same functionality today but you need 2 X $10,000 SMU's, and a computer,
and software so call it a $25,000 setup though given the catalog price
of the 576 and the 300's doesn't sound so bad now that I say it.

A long time ago in the early 80's the Massachusetts hams ran an auction
at Honeywell Inc
in Billerica. You could bring your old electronic stuff and they would
auction it off. It was
great fun and always well attended.

Anyway, one guy brought a 370 to be auctioned. As he wheeled it in on
a cart the crowd
chuckled. When it went up for auction it sold for $1 and the
auctioneer had a hard time
getting even that! Between then and now, what a great return on that
