CuriousMarc | Vintage HP Function Generators: HP 3300A, HP 3310A and HP 3312A @CuriousMarc | Uploaded 2 years ago | Updated 3 days ago
We have fun with HP 3300-series function generators, starting with the original 3300A in 1965, the cute and practical 3310A from 1970, and the full-featured 3312A from 1975. A decade of solid-state analog awesomeness, if you ask me. And many thanks to Keysight for providing the modern-day (and very digital) EDU33212, the current heir of the series.
