Measurement Results: emission bandwidth, namely the bandwidth between
two points on a signal which are X dB below the highest point within the span.
During the measurement, the analyzer first determines the frequency (f
0
) of the
maximum amplitude point within the span and then finds the two frequency points
(f
1
and f
2
) at each side of f
0
at which the signal amplitude is X dB below the
maximum amplitude. The emission bandwidth is f
2
-f
1
.
Measurement Parameters: average number, average mode, max hold, span
and X dB.
1. Avg Num
Specify the number of averages used when calculating the measurement
result and the default is “Off”. You can use the numeric keys, knob or direction
keys to modify this parameter.
