Analog Modulation Waveforms
The signal generator can modulate the RF carrier with four types of analog modulation:
• amplitude,
• frequency,
•phase, and
•pulse.
Available internal waveforms include:
Sine sine wave with adjustable amplitude and frequency
Dual-Sine dual-sine waves with individually adjustable frequencies and a percent-of-
peak-amplitude setting for the second tone (available from function generator only)
Swept-Sine swept-sine wave with adjustable start and stop frequencies, sweep rate, and sweep
trigger settings (available from function generator only)
Triangle triangle wave with adjustable amplitude and frequency
Ramp ramp with adjustable amplitude and frequency
Square square wave with adjustable amplitude and frequency
Noise noise with adjustable amplitude generated as a peak-to-peak value (RMS value is
approximately 80% of the displayed value)
