 The '''Tektronix 575''' is a curve tracer for transistors, [[introduced in 1957|introduced in March 1957]].
-It can be thought of as being composed of three modules:
-an X-Y display, a step source, and a collector sweep source.
+It can be thought of as being composed of three modules: an X-Y display, a step source, and a collector sweep source.
+Unlike later curve tracers, the 575 can optionally display base voltage on the vertical axis.

 ==History==
 [https://vintagetek.org/my-early-tektronix-days-by-john-kobbe-2/ John Kobbe says]:
 <blockquote>
-While I was working on the 540 series vertical amplifier, Virgil Briton, whose bench was next to me, had put together a vacuum tube curve tracer using stepping relays and other mechanical devices. I remember thinking that, that was a neat display even if it did a lot clicking and was slow. After putting the cross hatch generator together, I knew it would be very easy to do the curve tracer electronically,it started for in house use,but after putting a self-contained instrument together, Tek decided to call it 575 and sell it.
+When transistors started to become practical, Tek sent [[Bill Polits]] to Michigan, for a 2 week primer on transistors.
+He in turn communicated it to the rest of us who were interested. That called for a transistor curve tracer.
+It used a similar step generator as the tube curve tracer but otherwise needed mostly new circuits.
+I remember a day at the beach, I was trying to hide from the sun while everyone else was getting their sunburn.
+I dug the sand out from under our new 1954 Chevy, got comfortable and figured out the circuits for the curve tracer soon to become the 575.
+[[Deane Kidd]] did the hard part when he designed the switches.

 Early 575 versions used [[selenium rectifiers]].
 A kit for conversion to silicon diodes was available and is documented in the back of the manual.
-===CRT===
-The 575 uses the Tektronix [[T0520]] CRT.
-The 575 has a [[thermal cutoff]].
