WaveRider Operating Manual

Spectrogram Options Dialog Box

The Spectrogram Options Dialog Box provides the ability to change the appearance and

characteristics of the Spectrogram window.

Channels

Choose among the WaveRider channels (or among the saved channels, if an archive file is

being read); the chosen channels will be displayed in this Spectrogram window, one above

the other. Some of the channel checkboxes may be grayed, indicating channels that have a

different use category.

If multiple channels are displayed in one window, those channels become Linked; the ranges

of linked channels are always kept the same.

Timebase

Each of the vertical strips of color displayed in the Spectrogram window represents an

average of the frequencies over a selected number of seconds, ranging from a half second up

to 32 seconds. A longer timebase allows the Spectrogram window to display a record of the

frequencies over a longer period of time (up to several hours), while a shorter timebase

makes events such as a momentary burst of a certain frequency more visible.

Spacing

The default horizontal spacing uses one pixel per vertical strip. If x2 or x3 are selected, each

strip uses correspondingly more space in the window, making less data visible at one time.

Sample Color Bar

A sample is shown of the color range which is used to represent the frequencies. The

frequencies with the least amount of activity are depicted using the colors on the left end of

the sample, while frequencies with the greatest activity show as colors on the right end of the

sample. To select a different color scheme, choose the COLORS... command from the

OPTIONS menu.
