The generator output lead should be terminated with its characteristic impedance, usually 50 ohms. Use only enough sweep generator output to provide a usable pattern on scope. Connect a variable bias supply between TP-3 and chassis. The required bias will range from -1.5 to +3 volts. During alignment set bias to -K 2 volts unless otherwise stated. Adjust Al and A2 so that top of inner core is flush with top of outer core. SWEEP GENERATOR COUPLING Unplug IF cable from tuner and connect gener- ator across cable plug. Across antenna input jack.
