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
If calibrating model E4407B stop here and proceed to
paragraph 12. For all other models complete steps (13)
through (19) below.

(b) [Factory Preset] (if it is displayed).
(c) Sweep, [Points 401].
(d) FREQUENCY, 1, [GHz].
(e) SPAN, 1, [MHz].
(f) AMPLITUDE, [Ref Level], 9, [dBm].
(g) [Scale/Div], 2, [dB].
(h) Peak Search (or Search).
(i) SPAN, [Span Zoom], 5, [kHz]. Wait for the SPAN 5 kHz message to appear.
(j) BW/Avg, [Res BW], 1, 0, [Hz] (Man).
(k) SPAN, 1, 0, 0, [Hz].
(l) Peak Search (or Search), Marker , [ Marker Ref Level], Marker, [Off].
(m) Single. Wait for sweep to finish.
(n) Peak Search (or Search).
(o) [Meas Tools], [Delta].
(14) Adjust TI RPG knob ccw until the Mkr1 amplitude indicates within -9.7 and -10.3 dB.
(15) Press TI keys as listed in (a) through (g) below:
(a)
Marker, [Normal].
