accesses the softkey menu of functions that can be coupled. (Coupled
functions are functions that are linked: if one function is changed, the other
function is changed.) The functions that can be auto-coupled are listed below:
Video bandwidth couples to resolution bandwidth when the spectrum
n
analyzer has a video-bandwidth to resolution-bandwidth ratio of 0.3.
Sweep time couples to span, resolution bandwidth, and video bandwidth.
n
RF attenuation couples to reference level.
n
During normal operation, the sweep time, resolution bandwidth, and video
bandwidth are coupled to yield optimum performance. If any of these
functions becomes uncoupled (that is, is manually set), a "#" will appear next
to the screen annotation representing the function on the screen.
If one or more functions are manually set so that the amplitude or frequency
becomes uncalibrated,
Recouple a single function by pressing the function label (to activate the
function), and pressing the function again so that AUTO is underlined.
