4.8 Noise Table

Noise Table can plot on the chart of tank spectrum.

[Note] When plotting Noise Table, it is necessary to retrieve the data by clicking

[READ] button in the menu of “6. Noise” prior to plotting the table.

(1) Plotting points

After retrieving data of Noise Table, the table will be shown by blue line as Fig. 4.8-1.

Fig. 4.8-1 Noise Table (No points)

In order to plot a point, right-click on the plotting point. Then, so right-click-menu will be

opened as Fig. 4.8-2, select “ADD” to plot a blue point.

These blue points can drag in the chart area by mouse operation.
