A
All Pulse Generators are EH 137 or equiv.
Pulse Generators 1 and 2:
PRF = 10 MHz
PW = 50% Duty Cycle
t + = t – = 2.0 ± 0.2 ns
Pulse Generator 3:
PRF = 2.0 MHz
PW = 50% Duty Cycle
t + = t – = 5.0 ± 0.5 ns
50
VEE = –3.0 V
All resistors are +1%.
All input and output cables to the scope are equal lengths of 50 coaxial cable.
The 1950 resistor at Pin 7 and the scope termination impedance constitute a 40 :1 attenuator probe.
CT = 15 pF = total parasitic capacitance which includes probe, wiring, and load capacitance.
Unused output connected to a 50 resistor to ground.
