2.2 Auto Couple

Coupled functions are functions that are linked/dependent on other functions. Pressing
displays some of the most important coupled analyzer functions.
Auto Couple
An example of a coupled function is Res BW (resolution bandwidth). When Res BW is set to
auto, the Res BW is automatically set based on the span setting.
Coupled functions are affected depending on how they are coupled. For example, Video BW
is coupled to Res BW, so changing Res BW affects Video BW, but changing Video BW does
not affect Res BW. Changing Video BW puts it in manual (instead of auto-coupled). When
Video BW is set to

Coupled functions are functions that are linked. When

these auto settings give the most accurate measurements and optimum dynamic range.
When a function is coupled, it is in the
