Amplitude Sweep (cont'd)
Example for Calculation # 3
Set an amplitude sweep from -1 0 dBm to -21 dBm with 1 00 amplitude steps.
Calculate the required sweep time setting for the 100 amplitude steps using
calculation # 3 :
Maximum number of steps is equal to:
| - 1 0 dBm - (-21 dBm)\
0.1 dB
Minimum number of steps is equal to a minimum of:
5
110
or
| - 1 0 dBm - (-21 dBm)\
110
0.1 dB
Since 5 is less than 1 10, the minimum number of steps is 5.
Therefore, it should be possible to select 1 00 steps since that value is between the
minimum value (S) and maximum value (1 10).
To get 100 amplitude steps, you can set the sweep time between the results of the
following calculations:
(100 + 1) X 3 ms = 303 ms
(100 + 2) X 3 ms = 306 ms
