SW59, SW60 and SW61 = B
Assume the output amplitude at LPF high 5.5
TP43 when SIG1 (0dB, 100kHz)
is input to (A) as 0dB.
Vary the frequency of the input
signal to obtain the frequency
with an output amplitude of –3dB. LPF Low 4.0

SW59, SW60 and SW61 = B
Input SIG4 (VL = 0mV) to (A) and adjust
serial bus register BRIGHT so that the
output at TP43 is 9Vp-p (black-black).
