The '''Tektronix 1405 TV Sideband Adapter''' is a signal generator used with a spectrum analyzer such as the [[7L12]] or [[7L13]] to analyze the sideband response of a television transmitter or other video circuitry. | |||
The 1405 generates a composite video signal, the picture portion of which is a constant-amplitude sine wave signal that sweeps from 15-0-15 MHz. | |||
This signal is used to modulate the TV transmitter. The sideband response of the transmitter will be displayed on the spectrum analyzer. | |||
