All resistors are +1%.
All input and output cables to the scope are equal lengths of 50 Ω coaxial cable.
The 1950 Ω resistor at Pin 7 and the scope termination impedance constitute a 40 :1 attenuator probe.
C T = 15 pF = total parasitic capacitance which includes probe, wiring, and load capacitance.
Unused output connected to a 50 Ω resistor to ground.
