Figure 2-59 Frequency of the Combined Signals of the Radios
Using the time-gate capability and an external trigger signal, you can
see the separate spectrum of radio number one (or radio number 2 if
you wish) and identify it as the source of the spurious signal shown as
in Figure 2-60 and Figure 2-61.
