Sweep Time
Key access:
[BW/SWP] > {Sweep Time}
Selects the sweep time for the analyzer to tune across
the displayed frequency span (or, in zero span, the time
the analyzer take to sweep the full screen).Inputs may be
made using the knob, the arrow keys, or numeric
keypad.
In non-zero spans
When the sweep time is auto-coupled, the analyzer
selects the optimum (shortest) sweep time ranging from
10 ms to 1000 s. The auto selection is determined by
three measurement settings:
• Frequency Span
• The selected Resolution Bandwidth
• The selected Video Bandwidth
Note that changing one of the three factors above will
change the sweep time. The sweep time is in direct ratio
to frequency span and is in reverse ratio to the selected
resolution bandwidth and video bandwidth when
auto-coupled.
In zero span
Auto-coupled does not function when in a zero span.
The sweep time can only be set manually. The sweep
time is selectable from 6 s to 200 s in zero span.
NOTE
Reducing the sweep time increases the sweep rate.
CAU-
CAUTION
With sweep time set to a value less than the minimum
auto-coupled value, an annotation “Data out of range”
appears in the active function block and the sweep time is
automatically converted to the minimum auto-coupled value.
