integral within this bandwidth. You can use the numeric keys, knob or direction keys to modify this
parameter.
Table 2-32 Integration BW
Parameter
Explanation
Default
2 MHz
Range
100 Hz ~ Span
Unit
GHz, MHz, kHz, Hz
Knob Step
Integration BW/100, the minimum is 1 Hz
Direction Key Step
In 1-1.5-2-3-5-7.5 sequence
3. Span
Set the frequency range of the channel. This span which is the same with the span of the analyzer
is the frequency range of the sweep. Modifying this parameter will change the span of the
analyzer.
The channel power span is related to the integration bandwidth and the range available is
from integration bandwidth to integration bandwidth×20.
You can use the numeric keys, knob or direction keys to modify this parameter.
