Analog Modulation Waveforms
Analog Modulation Waveforms
The signal generator can modulate the RF carrier with four types of analog modulation: amplitude,
frequency, phase, and pulse. For pulse modulation information, refer to
Modulation (Options UNW and 320)”, on page 169
Available internal waveforms include:
Sine
sine wave with adjustable amplitude and frequency
Triangle
triangle wave with adjustable amplitude and frequency
Square
square wave with adjustable amplitude and frequency
Pos Ramp
positive going ramp with adjustable amplitude and frequency
Neg Ramp
negative going ramp with adjustable amplitude and frequency
Analog Modulation Sources
The signal generator provides the following internal and external modulation input sources. Internal
modulation sources generate the five waveforms listed above unless noted otherwise.
Ext1 & Ext2
an externally applied signal is used as the modulation input. Connect the signal to
the EXT 1 or EXT 2 connector on the rear panel of the instrument.
Func Gen 1
sine wave from the internal function generator. Instruments with Option 303 have
additional waveform choices listed above.
Func Gen 2
Func Gen 2 has the same capability as Func Gen 1. Available on instruments with
Option 303.
Dual Func Gen dual waveforms with individually adjustable frequencies and a percent-of-
peak-amplitude setting for the second tone. Available on instruments with Option
303.
Swept Func Gen swept waveforms with adjustable start and stop frequencies, sweep time, and
sweep trigger settings. Available on instruments with Option 303.
Noise Gen 1 & 2 noise with adjustable amplitude generated as a peak-to-peak value (RMS value is
approximately 80% of the displayed value). Uniform and Gaussian distribution is
available. Available on instruments with Option 303.
