The 1777 slope control adjusts the level at the highest frequency with respect to the lowest frequency displayed on the screen. The adjustment is easily made by observing the relationship between the high pilot level and the sweep points. As in the gain adjustment, you can measure the absolute level of the high pilot carrier and the sweep point next to it and adjust the slope until a difference of 10 dB is achieved.
