Level control — Adjusts the amount of compensation for  
amplitude losses caused by cable resistance.  
Max. rise/fall time ....................... 4 nS  
Polarity .......................................... RGBHV, RGBS ......... positive or negative  
(follows input)  
Peaking control — Adjusts frequency compensation. It is similar  
to the sharpness control on a television. It  
compensates for the effect of capacitance of  
long cables. Use the symbol at the left as a  
guide for adjusting the control.
