Re: Tektronix 570 Vacuum Tube Curve Tracer on eBay


Hi Eric,
Now that you mention it Tek had something like this. It is in the 1994 catalog on pages 414 and 415. It is called the Semiconductor Workbench. I just came across it for the first time and read the description last night. It seems like a very odd way to do things but who am I to say. I don't think it was in the catalogs for a very long time (just a guess). That would suggest there was little demand for it.

Since you mentioned Fluke did this too maybe Tek OEM'd the Fluke unit and put their name on it. Tek has bought other things from Fluke. They both have excellent engineering teams. They would both become even closer in 2007 when Danaher buys them both.

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

Anyway, one guy brought a 370 to be auctioned. As he wheeled it in on

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
