Fig. 3. Video system (input impedance)

Signal applied and measured from pins, 2, 4, 6, 8, 14, 16, 18, 20, 22, 24, 62, 64

Notes) 1. All +9V supplies de-coupled close to supply pins, 25, 47, 58 with 10nF ceramic capacitor.

2. Voltage measurements carried out with a high input impedance DVM. Typically 10GΩ.
