The Simulator’s Signal Editor provides tools to modify the base signal. The signal the simulator returns is always the base signal, plus noise, plus the interferer if turned on. This is true for all frequencies and spans. The trace signal does not vary when changing frequencies or RSMs.
The base signal can be modified as described in Edit the Base Signal. This is useful for testing drone tracking, where you need to change the base signal and insert a spurious signal and see how it is handled. The Signal Editor provides a trace view of the probes background sweep as shown in Figure: Signal Editor Trace Viewer.
Signal Editor Trace Viewer
Along the left edge of the signal editor are several buttons.
Auto-save
Automatically saves the trace.
Save
Save an edited trace internally and start using. Save the trace as Custom 1, Custom 2, etc. If not saved, the configuration will be lost when the simulator exits.
Add
Add current trace to signal list.
Remove
Remove the current trace from the list.
Restore
Restore to previous values.
Reset
Reset to factory default.
Capture
Capture trace signal from RSM.
Close
Close the Signal Editor.
Signal Editor Trace Display
The Signal Editor trace display shown in Figure: Signal Editor Trace Viewer provides signal information as determined from the signal list. When the mouse pointer is moved across the display, a green marker tracks the mouse pointer. Positioning the marker in the trace view display will show the frequency of the sweep at that point. The top left corner of the display provides the frequency at the peak region of the signal as shown.
Edit the Base Signal
Create a custom base signal that noise and the interferer are added to:
• Push the signal up and down with the mouse at each frequency point.
• Roll the mouse wheel to add or remove a Gaussian peak at the current mouse location.
• Roll the mouse wheel up or down to adjust amplitude at the current mouse coordinates.
• Right-click and drag the mouse to move the signal to the level of the mouse over the path.
