Table 2-36 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 2-37 Integration Bandwidth for Chan Power Measurement 
Parameter  Description 
Default  2 MHz 
Range  100 Hz to 7.5 GHz 
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.
