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.
