Sum Modulation
l Front Panel:
l SCPI: SUM:INTernal:FUNCtion {SIN|SQU|RAMP|NRAM|TRI|NOIS|PRBS|ARB)
Modulating Waveform Frequency
The instrument accepts an internal or external modulation source.On a two-channel instrument you can modulate
one channel with the other.
l Modulating frequency (internal source): 1 µHz to 30 MHz, default 100 Hz.

Sum Amplitude
The Sum Amplitude represents the amplitude of the signal added to the carrier (in percent of carrier amplitude).
l Amplitude setting: 0 to 100% of carrier amplitude, 0.01% resolution.
l Sum Amplitude remains a constant fraction of carrier amplitude and tracks carrier amplitude changes.
