6. Adjust function generator FREQUENCY to place generator signal

near the center graticule on the analyzer display.

7. Adjust the AMPLITUDE VERNIER on the function generator until

the peak of the generator signal is at the reference level line on

the analyzer display.

8. Press LOG [ENTER

on the analyzer and key in 1

per

division.

9. Adjust function generator AMPLITUDE VERNIER to place peak of

generator signal 2

(2 divisions) down from the reference level.

Do not readjust AMPLITUDE VERNIER during test.

10. Adjust FREQUENCY on the function generator to position the

signal trace at the right edge of the analyzer display.,

11. Press TRACE A

(MAX].

Press MODULATION SWP on

the function generator. When function generator completes

one sweep, press TRACE A (VIEW). Trace should appear as in

Figure 2-15.
