(1)Measure the amplitude of NFB V Ramp at Pin25, that is
"VNFB". (2)Measure the amplitude of NFB V Ramp at Pin25 for V-
Size 0/63, that is
VNFBMIN / VNFBMAX.
(3)Calculate; "
VVRAMPH"=(VNFBMAX-VNFB)/VNFB*100
"
VVRAMPL"=(VNFBMIN-VNFB)/VNFB*100

(1)For V Linearity 8, measure V1(from center to max.) and
V2(from center to min.) at Pin24 according to a follownig figure.
(2)For V Linearity 15/0, measure VLIN1+ / VLIN1- and VLIN2+ / VLIN2-.
(3)Calculate; "
