Sweep Time
Sweep Time
The
SWEEP TIME [ ]
or manual mode is active. The following explains the difference between automatic and manual sweep time:
• Manual sweep time. As long as the selected sweep speed is within the capability of the instrument, it
will remain fixed, regardless of changes to other measurement parameters. If you change measurement
parameters such that the instrument can no longer maintain the selected sweep time, the analyzer will
change to the fastest sweep time possible.
• Auto sweep time. Auto sweep time continuously maintains the fastest sweep speed possible with the
selected measurement parameters.
Sweep time refers only to the time that the instrument is sweeping and taking data, and does not include the
time required for internal processing of the data, retrace time, or band switching time. A sweep speed
indicator is displayed on the trace for sweep times longer than 1.0 second. For sweep times equal to or
faster than 1.0 second, the indicator appears in the status notations area at the left of the analyzer's
display.
Manual Sweep Time Mode
When this mode is active, the softkey label reads
whenever you enter a sweep time greater than zero. This mode allows you to select a fixed sweep time. If
you change the measurement parameters such that the current sweep time is no longer possible, the
analyzer will automatically increase to the next fastest sweep time possible. If the measurement parameters
are changed such that a faster sweep time is possible, the analyzer will not alter the sweep time while in
this mode.
Auto Sweep Time Mode
When this mode is active, the softkey label reads

time possible with the selected measurement parameters.
Minimum Sweep Time
The minimum sweep time is dependent on the following measurement parameters:
• the number of points selected
• IF bandwidth
• sweep-to-sweep averaging in dual channel display mode
• error-correction
• type of sweep
7- 12
softkey selects sweep time as the active entry and shows whether the automatic
