SWEEPLESS SWEEP (Optional Purchase
Required)
The following topics explain the user functions available within the Reverse
Sweep mode.
Softkeys
Three softkeys on the SWEEPLESS SWEEP screen provide the following options:
FILE
Save Reference...
Saves the current measurement as a reference file.
Save File...
Saves the current measurement as a static measurement file. NOTE:
When a saved static measurement file is opened, the graph will be one
similar to the live measurement graph.
TIP: To assure exact measurement recording of current display, always
pause (SHIFT 8) measurement updates before saving or printing a measurement
file.
Load Reference...
Proceeds to a work folder associated with reverse sweep reference files.
Select a desired reference file. If the file selected is not compatible
with the current received sweep plan, a message will alert the user. NOTE: This feature allows you to display
the difference of the live data and the data stored in the file.
When a reference file has been chosen for display, the name of the reference
file appears in the subtitle bar in place of 'REF: NONE'.
The maximum length of the file name is 12 characters. When an additional
file is saved, the file name field in the "save a file" display
will contain the last label saved. This label may be appended, altered,
cleared or simply saved unchanged. If saved unchanged, an "overwrite?"
warning will be displayed that must be acknowledged.
NOTE: Since a reference file is essentially an average of the data
obtained from four previous sweeps, enough traces need to accumulate before
a file can be saved and used as a reference file. Thus, when the forward
sweep screen is accessed for the first time, the subtitle bar initially
displays a cross in place of the reference file name. Once enough traces
have accumulated "REF: NONE" or the current reference file
label is displayed.
Load File...
Loads a file as a static measurement file.
Clear Reference
Removes reference file from measurement and returns the subtitle bar to
"REF: NONE".
VIEW
Several viewing options are available to assist you with data assessment.
Press the VIEW softkey. Use the
arrow keys to choose the menu item you prefer and press ENTER
to make your selection.
Select Auto Reference to automatically
view measurement results in the best reference setting on the graph (Keystroke
shortcut: SHIFT 9). NOTE: For
best reference setting results you may have to select the Auto
Reference button more than once (up to three times).
Select 1 dB/div, 2 dB/div, 5 dB/div, or
10 dB/div to adjust the vertical resolution of the graph for the
best viewing.
Select (or deselect) Zoom to
turn on and off graph magnification. When selected, the Zoom feature produces
a display that has a frequency span that is defined by the position of
the markers in the original non-zoomed view.
Select Pause to suspend measurement
updates (Keystroke shortcut: SHIFT 8).
Use the arrow keys to select Marker A
or Marker B as the active marker,
then press ENTER. Use the Left and Right
Arrows to move the marker.
