The Tektronix 577 is a curve tracer, introduced in November 1972, that uses plug-in test fixtures. The 177 is the standard fixture, which is intended for testing discrete devices like transistors. Also available is the 178, which is for linear ICs (voltage regulators and opamps).

The 577/D1 is the storage model, the 577/D2 the non-storage.

Tekscope Nov 1972 says:

Jack Millay headed up the very able team which designed the 577 Curve Tracer Measurement System. Working on the electrical design were Jim Knapton, Bob Herb, Bob Verrinder, Om Agrawal, Dave Rule, and Gary Davis. Tom Saucy did the mechanical design while Darrell Barrett and Gil Stephens provided evaluation support. Lena Mcintosh and Iona MacKay built the prototype instruments. And there were many others who helped in both large and small ways to make this project a success.
