Tektronix CFG 280 Function Generator The CFG280 is capable of generating triangle, sine, or square waves. The frequency of the output is variable from approximately l Hz to 100 MHz. The frequency and amplitude controls are shown on the graph. The output of the function generator is taken from the BNC jack labeled “MAIN OUT" or “SYNC OUT”. The cable attached to BNC connectors will have two tips, the black tip which should be grounded and the red tip which serves as the source of the output wave. The “SYNC OUT” outlet produces a square wave of the amplitude of about 5V. Signal frequency can be read on the display. For signals generated internally by CFG280 the SOURCE button (pointed to by the yellow arrow in the figure above) must be pushed out. The frequency of the wave is adjusted by the coarse “MULTIPLIER” buttons and the fine “FREQUENCY” dial. The left “MULTIPLIER” button raises the frequency by the factor of 10 each time it is pressed. The right “MULTIPLIER” button lowers the frequency by the
