6-15.8 Display Settings
The spectrum analysis function offers 4 display modes: curve, solid, spectrogram, curve/spectrogram, and
inverted (print) mode. Tap Display to enter the menu, then select from the following modes.
Curve mode
Curve is the standard Spectrum Analysis display mode.
Solid mode
The solid mode fills the area below the signal with solid
yellow, shown left.
Spectrogram mode
The scrolling three-dimensional display is useful for tracking
frequency and power over time. Use Spectrogram mode to
verify a signal's stability over time, or to identify intermittent
interference signals. The X-axis (horizontal) shows frequency,
the Y-axis time (with new data scrolling bottom-to-top), and
amplitude is represented by color (red for a high level signal
and blue for the noise floor).
Curve+Spectrogram mode
The best setting for many scenarios, the simultaneous
spectrum trace and scrolling three-dimensional display
provides a definite advantage in using the combined mode
from a visual stand-point. (It will be much easier to visualize
signal variations, such as a hopping frequency signal.)
Print Mode
New to the S7200 is Print mode. By inverting the screen
colors from dark background and a light trace color to a
light background and a dark trace color, printing hard
copies of saved traces is more cost-efficient. This mode also
makes traces easier to see in strong sunlight.
