Point Limit: Press this soft key to select a single limit point or an entire limit
line. Changes in limit frequency or amplitude affect the limit point or limit line
that is selected by this soft key. The selected feature is underlined on the key.
Limit X: Press this soft key to change the frequency setting of the limit point

The current frequency setting is shown on the soft key face.

Amplitude: Press this soft key to change the amplitude setting of the limit

point or limit line, as determined by the underlined selection on the Move soft
key. The amplitude of each limit point can be individually set. By default, when
Limit X
a new point is added, it takes on the amplitude that is on the limit line at the
# kHz
frequency where the point was added. Use the number keypad, the arrow
keys, or the rotary knob to move the point to the desired value. When using
Amplitude
the number keypad, use the +/– key for entering a minus sign. The unit of the
#
amplitude limit is the same as the current vertical amplitude unit. Refer to the
Add Point soft key description for more details. The current amplitude setting
is shown on the soft key face.

Point
Add Point: Press this soft key to add a limit point. The precise behavior of
this soft key depends upon which limit point is active at the time that the key is
pressed. If the active limit point is somewhere in the middle of a

multi-segment limit line, then a new limit point will be added halfway between
the currently active point and the point immediately to its right. The amplitude

of the point will be such that it falls on the limit line. For example, if a limit point

is at 2.0 GHz with an amplitude of –30 dBm, and if the next point to its right is

3.0 GHz with an amplitude of –50 dBm, then the added point will be at
2.5 GHz with an amplitude of –40 dBm. The frequency and amplitude values

of the new point can be adjusted as needed with the Frequency (Limit X) and

Amplitude soft keys.
If the last (furthest right) limit point is active (assuming that it is not at the right
edge of the display), then the new limit point will be placed at the right edge of

the display at the same amplitude as the point immediately to its left.
Points may not be added beyond the current sweep limits of the instrument.
Delete Point: Press this soft key to delete the active (selected) limit point.
The active point becomes the point immediately to the left of the deleted point.
Next Point Left: Press this soft key to select the limit point immediately to
the left of the active point, making this point active for editing or deletion. With
each key press, the indicator (of which point is active) moves one limit point to
the left until it reaches the left edge of the sweep window.
Next Point Right: Press this soft key to select the limit point immediately to
the right of the active point, making this point active for editing or deletion.
With each key press, the indicator (of which point is active) moves one limit
point to the right until it reaches the right edge of the sweep window.
Back: Press this soft key to return to the
