SUM modulation
Sum modulation adds a modulating signal to a carrier wave.
Typically, sum modulation is used to add noise to a carrier wave.
The modulating signal is added as a percentage of the carrier
amplitude.
If SUM is enabled, any other modulation mode will be disabled.
Likewise, burst and sweep modes cannot be used with SUM and
will be disabled when SUM is enabled.
