Key Reference
Sweep
Sweep
Accesses the Sweep softkeys for selection of the sweep mode
and trigger mode of the analyzer. The softkey menu
selections are defined as follows:
Sweep Time
Auto Man
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.
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.
