Averaging Measurements

Averaging Measurements

When the averaging function is enabled on the IQS-1700 High Performance 
Power Meter, the most recent measurement samples, for which you can 
set the number, are used to compute an unweighted average. This average 
is displayed as the measured value. The 

AVG

 marker will also be displayed 

to the right of the value for the matching channel, indicating that averaging 
is enabled.

Averaging can be done on a minimum of 2 and a maximum of 1000 points 
(you can enter 1 as a value, but the averaging will be performed only on 
that value and will be rather useless). The calculation uses watt as unit, but 
the result will be converted into the unit you have selected for your 
acquisition (W, W/W, dBm or dB) afterwards.

The formulas used to calculate measurement averaging depend on the 
number of the current acquisition.

If n 



M, then

Where

n

 is the number of the current acquisition

M

 is the number of points to average (value you set)

x[n]

 is the current sample in watts

y[n]

 is the result of the present average in watts

y[n-1]

 is the value before the average in watts
