Sweep Time
The fastest possible sweep time is always used as the default setting. Use the
Min Swp Time setting to slow the sweep time when measuring long lengths of
cable. Learn more at the FieldFox Supplemental Online Help:
http://na.support.keysight.com/fieldfox/help/SupHelp/FieldFox.htm
The actual sweep time is shown on the FieldFox screen. See the Screen Tour
on “Screen Tour” on page 33. To increase the sweep time, enter a value that is
higher than the actual sweep time. The increase will not be exactly the amount
that you enter, as the actual sweep time is the composite of many factors.
How to set Sweep Time

.
—Then Min Swp Time

— Enter a value using the numeric keypad.

external TTL signal at the Ref In/Trig In connector on the FieldFox top
panel.
——When the FieldFox is armed for an external trigger signal, Wait
is annotated on the display.
Measurement speed specifications do NOT apply in Temperature Control
