NOTE
If displayed trace is not approximately 5 divisions below the
reference level, press Sweep, Sweep (Cont) keys and then
FREQUENCY key. Adjust the RPG knob to place displayed
trace approximately 5 divisions below reference level. Press
Single.
(10) Press Peak Search (or Search) key then [Pk-Pk Search] key.
(11) Record absolute value of Mkr1 amplitude indication.
(12) Multiply value recorded in (6) above by value recorded in (11) above. Result will
be ≤ 150 Hz for model E4407B and ≤ 100 Hz for all other models.
NOTE
