577

Manuals – Specifications – Links – Pictures

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.
