Sweep/Trig
Set parameters about the Sweep and Trigger functions, including sweep time, auto
sweep time, sweep mode, number of sweep, trigger type, etc.
Sweep Time
Set the time needed for the spectrum analyzer to finish a sweep within the span
range. The sweep time can be set in "Auto" or "Manual" mode and the default is
"Auto".
Key Points:
In non-zero span, the analyzer selects the shortest sweep time on the basis of
the current RBW and VBW settings if Auto is selected.
Decreasing the sweep time would speed the measurement. However, an error
may be caused if the specified sweep time is less than the minimum sweep
time in Auto coupling; at this point, "UNCAL" is shown in the status bar on the
screen.
You can use the numeric keys, the knob, or the arrow keys to modify the
parameter. For more details, please refer to "
".
