toggles the power slope function on or off. With slope on,
the output power increases with frequency, starting at the
selected power level.
defines a sloping limit line segment that is linear with
frequency or other stimulus value, and is continuous to the
next stimulus value and limit. If a sloping line is the final
segment it becomes a flat line terminated at the stop
stimulus. A sloping line segment is indicated as SL on the
displayed table of limits.
displays a Smith chart format. This is used in reflection
measurements to provide a readout of the data in terms of
impedance. It provides information such as the reflection
coefficient and input/output impedance of the DUT

lets you change the value of the smoothing aperture as a
percent of the span. When smoothing aperture is the
active function, its value in stimulus units is displayed
below its percent value in the active entry area.
Smoothing aperture is also used to set the aperture for
group delay measurements. Note that the displayed
smoothing aperture is not the group delay aperture unless
smoothing is on.
turns the smoothing function on or off for the active
channel. When smoothing is on, the annotation "Smo" is
displayed in the status notations area.
turns the source power on or off. Use this key to restore
power after a power trip has occurred. (See the
key description.)
