Sweep
In HP8903B mode, the source frequency is logarithmically swept. The number of frequency
points in a sweep is determined by the sweep width (ratio of the stop and start frequencies)
and the selected sweep resolution. The maximum number of points allowable in a sweep is
255. The frequency points in a sweep can be computed by using the following formulas:
Where n is the frequency point number (0 is the start frequency) and k is the number of
points per decade. Refer to the HP8903B special function codes, 17.0 to 17.9 as listed in
Table 8-6. The frequency point formula for reverse sweep is as follows:
Select Sweep in the HP8903B menu page to configure the HP8903B sweep settings.
