(5) Adjust synthesizer/level generator amplitude to position the signal for a marker
amplitude reading of -5 dBm +/- 0.2 dB.
(7) Set synthesizer/level generator AMPTD INCR to 3 dB.
(8) Press TI Peak Search (or Search), Marker, [Delta].
(9) Press synthesizer/level generator AMPLITUDE key then INCR ⇑ key.
(10) Press TI Marker key, then lower the marker frequency by adjusting the RPG
knob (ccw) until the marker delta amplitude is 0 +/- 0.05 dB.
(11) Record the marker frequency readout as the lower 3 db frequency in table 17.
(12) Raise the TI marker frequency by adjusting the RPG knob (cw) until the marker
delta amplitude is 0 +/- 0.05 dB.
(13) Record the marker frequency readout as the upper 3 db frequency in table 17.
(14) Subtract the lower 3 dB frequency recorded in (11) above from the upper 3 dB
frequency recorded in (13) above. The result will be within the limits specified in table 17.
(15) Press synthesizer/level generator AMPLITUDE key.
(16) Press synthesizer/level generator INCR ⇓ key.
(17) Press TI Marker, [Normal] keys.
(18) Repeat technique of (4) through (17) above for the TI BW and SPAN settings

(19) Set synthesizer/level generator AMPLITUDE to -7 dBm.
(20) Press TI keys and enter values as listed in (a) and (b) below:
(a) BW/Avg, 120, [kHz].
(b) SPAN, 180, [kHz].
(21) Press TI Peak Search (or Search), [Meas Tools], [Mkr → CF].
(22) Adjust synthesizer/level generator amplitude to position the signal for a marker
amplitude reading of -7 dBm +/- 0.2 dB.
