MOTOROLA RF/IF DEVICE DATA

–

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

All resistors are + 1%.

All input and output cables to the scope are equal lengths of 50–ohm coaxial cable.

The 1950–ohm 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–ohm resistor to ground.
