9. Repeat steps 4 through 9 for
all
remaining (CENTER FREQUENCY]

Table
2-20. Steps 4 through 8
need only be done once for each (CENTER FREQUENCY) setting.
10. Set the synthesized sweeper for an output CW frequency of
5700.000 MHz.

amplitude of the multiples for a given signal frequency, set the
input signal amplitude by the procedure of steps 11 through 14.
