Selecting a window
The traces recorded by a sensor in the Scope mode can be displayed in an expanded or a half-height
window. The most important thing is that the sensor that has been switched to the Scope mode is en-
tered in the
Primary Channel
of this window (
Functions and their use, p. 4.34).
The window should be expanded so that the additional control elements of the Scope mode display can
be used. As usual, the functions in the
Windows
menu are used to switch between the expanded
Expand
(p. 4.29) and half-height window

(p. 4.29).

Trigger settings
To obtain a stable image, the trigger parameters must be set in the Trigger and Trigger (Adv.) dialog
boxes so that they correspond to the signal (
Trigger settings and Trigger sequence control, p. 4.24).
Filter settings
Like any other result of a power measurement, the displayed trace can also be smoothed using the
averaging filter. For this purpose, a number of sweeps are recorded, and the corresponding points of
each sweep are averaged. For configuring the filter
Filter / averaging, p. 4.19. To prevent the meas-
urement result from being corrupted by unstable trigger conditions (non-correlating points of different
sweeps are averaged), a test should first be run in the Realtime mode to determine whether stable trig-
ger conditions exist (
Realtime, p. 4.42).
