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.
