Auto Couple
Accesses the menus to couple functions in your analyzer. Coupled
functions are functions that are linked.
Auto All
Auto-couples all coupled functions. If
Auto All
is pressed all coupled
functions are set to
Auto
.
NOTE
This function is not available when the segmented sweep function is set
to On, (
Segmented (On)
).
Coupled functions are functions that are linked. If one function is
changed, the coupled function is changed. During normal operation, the
sweep time, resolution bandwidth, video bandwidth, and center
frequency step are coupled to span; the input attenuation is coupled to
the reference level.
If any of these functions become uncoupled (is set to manual), a # sign
appears 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 “Meas Uncal” appears on the top
right side of the graticule.
To recouple the analyzer functions, the uncoupled function(s) must be
individually set back to Auto. Or, you can press
Auto All
to return all of
the functions to their default auto state. Pressing
Auto All
will couple
the following functions:
• Sweep time will couple to the span, detector mode, resolution
bandwidth, and video bandwidth.
•
Detector (Auto)
is set.
•
Avg Type (Auto)
is set.
•
PHNoise Opt (Auto)
is set.
• RF attenuation couples to reference level.
• Center frequency step size will couple to 10% of span.
• Sweep coupling (SR/SA) will couple back to SA mode.
• Source attenuation couples to source amplitude.
• Source power step couples to one vertical scale division.
