C2009/C2010:
100:1 Attenuator compensation CH I
Do not adjust until the adjustment of item 15 has been made.
– Locate and identify trimmers C2009 and C2010 for CH I on
YP-Board.
– Set input coupling to DC.
– Set attenuator CH I to 0.5 V/div.
– Set amplitude calibrator output voltage to 5 V
pp
(2.5 V
pp
at
the 2:1 pre-attenuator output) terminated with 1MΩ (oscil-
loscope input impedance).
– Adjust C2009 for a fl at top.
– Adjust C2010 for a leading edge without overshoot.
– Repeat C2009 and C2010 adjustment until optimum is ob-
tained.
