MOTOROLA RF/IF DEVICE DATA
Figure 1. AC Tests
NOTES:
1 All input and output cables to the scope are equal lengths of 50
coaxial cable.
2 Unused input and outputs are connected to a 50
resistor to
ground.
3 The device under test must be preconditioned before performing
the ac tests. Preconditioning may be accomplished by applying
pulse generator 1 for a minimum of two pulses prior to pulse gen-
erator 2. The device must be preconditioned again when inputs to
pins 6 and 9 are interchanged. The same technique applies.
