STEP SETTING
As in the case of frequency sett ing, the leve 1 s e t t ing can also be done by
changing the level in steps.
For the sett ing procedure, refer to the Sect ion "4-1-3 Step Sett ing".
instead of the FREQ (MHz) key ment ioned in the i n s t r u c t ions, the LEVEL (dB)
key shou 1 d be used and
