(d) FREQUENCY, [Center Freq], 1, [GHz].
(e) SPAN, 1, [MHz].
(f) AMPLITUDE, [Ref Level], 9, [dBm].
(g) [Scale/Div], 2, [dB].
(h) BW/Avg, [Res BW], 1, [kHz].
(i) Peak Search (or Search)
(j) SPAN, [Span Zoom], 5, [kHz]. Wait for the SPAN 5 kHz message to appear.
(k) Peak Search (or Search), Marker →, [ Marker →Ref Lvl], Marker, [Off].
(l) Single. Wait for sweep to finish.
(m) Peak Search (or Search).
(n) [Meas Tools], [Delta].
(4) Adjust TI RPG knob ccw until the Mkr1 ∆ amplitude indicates between -7.7 and
-8.3 dB and press [Delta] key.
(5) Adjust TI RPG knob ccw for a Mkr1 ∆ indication between -3.7 and -4.3 dB.
(6) Divide Mkr1 ∆ frequency (in Hz) by Mkr1 ∆ amplitude (in dB) to obtain slope of
resolution bandwidth filter and record result.
EXAMPLE: If Mkr1 ∆ frequency is 380 Hz and Mkr1 ∆ amplitude is 3.92 dB
then slope would be: 380 Hz 3.92 dB = 96.94 Hz/dB
