To Display a Math Trace:
1. From the Main Menu, select Traces or press F2.
2. From the Traces Sub-Menu, select Math or press F4.
3. Select the Math icon. Note: If a math trace has already been set up once during your current
session, you will need to use the Edit icon to change the math trace.
4. From the drop-down menus in the Edit Math Trace dialog box, select traces for Trace A and
Trace Band select OK. The math trace will open in a tabbed window below the spectral display.
The example below shows a comparison between the peak trace and real time trace.
Several other tasks related to the math trace can be performed from the Traces|Math Sub-Menu.
• Math – Once a math trace has been set up, pressing the Math icon again will hide the math
trace. Each subsequent press of the Math icon will toggle the display of the math trace. Only
one math trace can be displayed at a time.
• Mask – Compares the realtime trace to a stored mask trace and adds a signal to the signal list
when the difference exceeds a user defined threshold. This comparison is done on a sweep by
sweep basis. If the real time signal remains above the threshold then there is only one event
added to the list. If the realtime signal drops below the threshold and then exceeds the
threshold again, another event will be added to the signal list. The signal list table includes
frequency, power, bandwidth, timestamp, last seen timestamp and count information.
