The spectrum analyzer has the function of channel power measurement. You can measure the channel power of
the signal by setting relevant parameters in the functional menu and selecting the appropriate resolution bandwidth
and span. Refer to the channel power measurement requirements in the first section of this chapter for specific
operations.
· [Channel Power Off On]:
Press [Measure]→ [Channel Power]→
[Channel Power Off On] to enable or disable the channel power
measurement function.
· [Center frequency]:
Press [Measure]→ [Channel Power]→ [Center
Freq] and set the center frequency with number keys.
· [Channel BW]:
Press [Measure]→ [Channel Power]→ [Channel BW]
and set the channel bandwidth with number keys.
· [Span]:
Press [Measure]→ [Channel Power]→ [Span] and set the
channel span with number keys.
· [Special attention]: The channel power bandwidth refers to the
frequency width of the power displayed by the spectrum analyzer
within the bandwidth, while the channel power span refers to the
sweeping frequency range of the spectrum analyzer. The channel
power span should be more than or equal to the channel power
bandwidth. Otherwise, the channel power bandwidth will be
automatically set to be equal to the channel power span. The ratio of
the channel power span to channel power bandwidth is a constant. It
remains unchanged when the channel power span is changed. You
can change this ratio by changing the channel power bandwidth. For
example, when the channel power span is doubled, the channel
power bandwidth will be increased by the same times.
Results can be rapidly, clearly and accurately in occupied bandwidth measurement of the spectrum analyzer.
Depending on the modulation mode, two methods can be applied to calculate the occupied bandwidth: power
percentage and power drop XdB. The user can select the appropriate occupied bandwidth measurement method
according to the needs. Refer to the occupied bandwidth measurement requirements in the first section of this
chapter for specific operations.
