Sweep
Segmented Sweep Editor
When the editor is entered (
Sweep, Segmented, Modify, Edit), the
segmented sweep mode is turned on, and a dual-display appears. The
upper window shows the trace, displayed as described above. The lower
window shows the editor data in tabular form: one segment per row
with segment number and parameter values occupying the seven
columns. The paramenters that can be set are:
•Center Freq
•Span
•Resolution BW
•Video BW
•Points
•Sweep Time (Zero Span only)
The trace is updated after each segment has a complete row of data
entered. Although thirty-two segments are possible, only 8 rows of data
are shown in the table at a time.
Use the softkey menu to navigate the editor. When defining a new
segment, use the numeric keypad to set values. Pressing Enter places
the value in the table and highlights the next parameter available for
modification.
NOTE The order of the segments may change when you enter center frequency
or span because the sequence is based upon increasing start frequency.
Various parameters are coupled to ensure accurate measurements. You
will not be able to enter a value that would result in a measurement
that is uncalibrated.
Amplitude parameters are common to all segments and are defined via
the amplitude softkey menu. Refer to page 6-8 for more information.
The data in the segmented sweep table is retained through a power
cycle. Table values can only be deleted by the
Delete keys described
below.
To exit the editor press any key except Print, Help, and the viewing angle
adjustments.
NOTE Exiting the editor does not turn off segmented sweep. Segmented (Off)
must be selected.
