AD INSTRUMENTS S7200 TV Signal Analyzer Operation Manual
Curve mode
The curve mode is the standard default Spectrum Analysis mode
Solid mode
The solid mode fills the area below the signal with a solid color. (yellow) as per
Figure 6-143 below.
Spectrogram mode
The scrolling three-dimensional display is useful for its ability to track frequency
and power behavior over time, particularly intermittent signals. You can use the
spectrogram mode to analyze the stability of a signal over time, or to identify
intermittent interference signals. The X-axis (horizontal) represents frequency,
amplitude is represented by color, (red for a high level signal and blue for the noise
floor). The Y-axis (vertical) represents time, with the most recent trace acquisition
displayed at the bottom of the graph to the oldest acquisition at the top of the
graph. (upwards movement of acquisitions)
Figure 6-144 Snapshot: Spectrogram display mode
The Curve- Spectrogram mode provides simultaneous display of spectrum trace
and spectrogram. There is a definite advantage in using the combined mode from
