FM Modulation
The Bird Site Analyzer uses FM modulation to
improve its immunity to interfering signals. Under
certain circumstances, such as while making cable loss
or other high reflection measurements with long
cables, FM modulation may reduce signal quality. In
that case, the modulation should be turned off.
y FM modulation is on by default, and will be turned
back on whenever the unit is reset to defaults.
y FM modulation is automatically turned off while
the unit is in Cable Loss Mode and returned to its
previous state on exiting Cable Loss Mode.
y Saving a setup saves the status of the modulation.
