Note
If the modulation source is set to external, the phase
deviation is controlled by the ±5V MOD INPUT terminal
on the rear panel. For example, if the modulation voltage
is +5V, then the phase deviation is equal to the phase
deviation setting. If the modulation voltage is less than
+5V, then the phase deviation will be less than the phase
deviation setting.
