BNC RTSA7500 Real Time Spectrum Analyzer Version 0.9

•

Time domain plot (right side): shows a trace for the In-phase (I data in green) and a trace for the quadrature (Q data in red, if available in the mode)

1. Open the View menu, and select I/Q Plots from the drop-down menu.

The I/Q plots appear below the main signal waveform display.

2. To hide the I/Q plots, open the View menu and deselect the I/Q Plots option.

Displaying the Spectrogram

You can view a spectrogram display of captured signal information. The spectrogram displays spectrum changes over time in a three-dimensional view. Time is displayed on the horizontal axis, and frequency on the vertical axis. The amplitude of the frequency components is expressed by color.

1. Open the View menu, and select Spectrogram from the drop-down menu.

The spectrogram plot appears below the main signal waveform display.

2. Optionally, you can enhance the display of the signal(s) of interest by sliding the triangles on the color palette (to the left of the display) to adjust the threshold at which the signal changes color. This allows the user to specify colors for each noise floor level.

3. To hide the Spectrogram plot, open the View menu and deselect the

Spectrogram Plot option.
