A frequency synthesizer and pulse/function generator are used
to input pulses to the spectrum analyzer. The amplitude of the
pulses is measured, and the impulse bandwidths are calculated for
each impulse bandwidth from 3 MHz to 1
kHz.
The 6
dB
resolution
bandwidths are then measured using the spectrum analyzer
(JiiKK]
function. The CAL OUTPUT signal is used as a stable signal source to
measure the 6
dB
resolution bandwidths.
