Note
When the source is set to EXT (external) the
carrier waveform is modulated by an external
signal. The frequency deviation is controlled by
the ±5V signal that is input into the MOD input
port. The ±5V input signal directly corresponds
to the set frequency deviation. +5V increases the
frequency by the set deviation frequency and -5V
reduces the frequency to below the carrier
frequency by the amount set by the deviation
frequency. For example: if the deviation
frequency is set to 1kHz, an input voltage of +5V
will increase the frequency to 1kHz, whilst an
input voltage of -5V will reduce the frequency
below that of the carrier by 1kHz.
