Note
The Scope channel A and B input attenuator top shieldings are provided with a
plate spring. The spring end is provided with heat conducting tape; it contacts
the C-ASIC’s N1000 and N1200, and transports the heat from the C-ASIC to the
shielding.
Do not bend the springs, keep the tape on the spring end free of dust, and put the
shielding on the correct position.
