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.
