Frequency span readout accuracy
Using the setup shown in the figure below, set the frequencies corresponding the 1st and 9th division from the
left side of the screen scale with the SG. The frequency difference between the peak levels at the 1st and 9th
divisions is equal to the frequency span×0.8.
(1) Specifications
