The beatnote frequency is set by the relative frequency difference between the
two sources. If you have two very accurate sources set at the same frequency,
the resulting beatnote will be very close to 0 Hz.
Searching for the beatnote will require that you adjust the center frequency of
one of the sources above and below the frequency of the other source until the
beatnote appears on the oscilloscope’s display.
If incrementing the frequency of one of the sources does not produce a
beatnote, you will need to verify the presence of an output signal from each
source before proceeding.
NOTE
If the center frequencies of the sources are not close enough to create a beatnote within
the capture range, the system will not be able to complete its measurement.
