Calculation #3
Set an ampli tude sweep from -10 dBm to - 21 dBrn wi th 100 amplit IIde steps.
Calculate the required sweep time setting for the 100 amplitude steps using
calculation #
3:
Maximum number of steps is equal to:
1-10 dBm -
(-21
dBm)
I
0.1 dB
=
110
Minimum number of steps is equal to a minimum of:
5
or
1-10 dBm - (-21, dBm)
I
0.1 dB
110
Since 5 is less than 110, the minimum number of steps is 5.
Therefore, It should be possible to select 100 steps since that value is between the
minimum value (5) and maximum value (I 10).
To get 100 amplitllde steps, you can set the sweep time between the results of the
following calculatiol\S
