Ebook: Spectrum Analyzer Circuits

In the 60's and 70's, Tektronix was known for the superb precision and high-frequency circuit design. To learn about circuit design, students of engineering would study the designs coming out of Tektronix for clues about how to achieve such remarkable performance. I recall using a Tektronics 7904 1GHz analog 'scope in the 80's and just being astonished by the clarity and precision of the displays.

The Tektronix engineers wrote a series of texts about the problem of measurement in general, and how to design the circuits to reveal the secrets of the domains being measures.

Manuals issued during this most productive time, even today's engineers can learn a great deal by studying the designs in these books.
