Table 2-35 Average Number for Chan Power Measurement
Parameter Description
Default 10
Range 1 to 1000
Unit N/A
Knob Step 1
Direction Key Step 1
2. Avg Mode
Set the average operation mode to “Exp” or “Repeat” and the default is “Exp”.
 When “Exp” is selected, the result is the exponential average of the
current N (N is specified in “Avg Num”) measurement results.
 When “Repeat” is selected, the result is the arithmetic average of the
current N (N is specified in “Avg Num”) measurement results.
3. Integ BW
Set the frequency width of the channel to be tested and the power of the
channel is the power integral within this bandwidth. You can use the numeric
keys, knob or direction keys to modify this parameter.
Table 2-36 Integration Bandwidth for Chan Power Measurement
Parameter Description
Default 2 MHz
Range 100 Hz to 7.5 GHz
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
4. CH Pwr 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.
