Adjusting Sweep Time
1. Press
Sweep/List.
This opens a menu of sweep control softkeys and displays a status screen summarizing all the
current sweep settings.
2. Press
Configure Ramp/Step Sweep.
Since ramp is the current sweep type, softkeys in this menu specifically control ramp sweep
settings. When step is the selected sweep type, the softkeys control step sweep settings. Notice
that the
Freq Start and Freq Stop softkeys appear in this menu in addition to the Frequency hardkey
menu.
3. Press
Sweep Time to Manual > 5 > sec.
In auto mode, the sweep time automatically sets to the fastest allowable value. In manual mode,
you can select any sweep time slower than the fastest allowable. The fastest allowable sweep time
is dependent on the number of trace points and channels being used on the 8757D and the
frequency span.
