1450
The Tektronix 1450 is an NTSC television demodulator. It requires a TDC, TDC1 or TDC2 down converter plug-in. It can also be used with a TDC-10 tunable downconverter, then an 015-0649-00 interface module needs to be installed in the 1450.
Tekscope V10 N3 (1978) says,
Project Manager Chuck Barrows provided overall direction, with Charlie Rhodes challenging us with the seemingly impossible while providing many valuable inputs. Assisting in electrical design were Jim Zook, front-end design (including the ceramic core resonators); Keith Ericson, IF and synchronous detector; and Dan Nicholas, AGC and audio. Bill Drummond, Tek Labs, was responsible for the SAW filter designs; and Oscar Olson, Hybrid Circuits Engineering, worked with Jim Zook on the helical resonators. The front-end precision attenuators are the work of Jack Roberts, Frequency Domain Instrumentation. Paul Chadwick handled the mechanical design. Much credit is also due Ellis Workman for his circuit board layouts, and Bob Thacker in smoothing the transition to manufacturing. Prototype support technicians were Sherry Self and Kerry Montgomery.
