Introduction
The Spur List function provides a listing of the frequency and amplitude
of up to 100 spurs. The HP 3048A marks all detected spurs with a dotted
line.
The criteria for marking spurs is a function of the measurement BW
and the amount the spur projects out of the noise. For offset frequencies
less than or equal to 100 kHz, the amount the spur must project above the
noise level to be marked as a spur is a function of the number of averages
taken. All marked spurs are displayed at their true level. Only the marked
spurs will be listed in the Spur List. Table 4-4 shows the amount spurs
must project out of the noise to be marked.
