3D Cursor Reader

The Waterfall Plot and the Spectrogram have different 3D cursor readers.

3D Cursor Reader for Waterfall Plot

The cursor reader will be shown when you left click anywhere within the plot area of the bottom plane (X-T). The contour of the spectral profile with a time stamp nearest to the point of mouse click will be highlighted (thus T is determined). This profile will also be projected onto the front plane (X-Y) so that it can be easily viewed against the X and Y scales. Within this profile, the cursor reader will point to the measurement point with a frequency nearest to the point of mouse click (thus X is determined). With T and X determined, Y is thus determined from the measurement results. The cursor reader always appears as a pair, one for each channel. The cursor’s (X, Y, T) readings for both channels are displayed on the top the graph. Their difference in Y is also shown.

3D Cursor Reader for Spectrogram

The cursor reader will be shown when you left click anywhere within the Spectrogram (X-T). The spectral profile with a time stamp nearest to the point of mouse click will be extracted and displayed at the bottom of the Spectrogram (thus T is determined). Within this profile, the cursor reader will point to the measurement point with a frequency nearest to the point of mouse click (thus X is determined). With T and X determined, Y is thus determined from the measurement results. The cursor reader always appears as a pair, one for each channel. The cursor’s (X, Y, T) readings for both channels are displayed on the top the graph. Their difference in Y is also shown.

Time Stamp

The time stamp of the latest spectral profile is displayed at the bottom of the 3D graph, and the time stamp of the oldest spectral profile is displayed on the top the 3D graph.
