5
step in the sweep.
Select the Number of steps field and enter a value (the default is 201 and the maximum is 2000). As the source
6
sweeps the power or frequency range, it divides the range by this number, resulting in the number of individual
instrument settings that the instrument makes when progressing through the sweep range.
Select the Dwell Time field and enter a value (the default is 0 seconds). This is the time the instrument stays at
