Signal Generator Overview
Modes of Operation
Digital Modulation (Vector Models with Option 65x Only)
In this mode, the signal generator modulates a CW signal with an arbitrary I/Q waveform. I/Q
modulation is only available on vector models. An internal baseband generator (Option 65x) adds
the following digital modulation formats:
— Custom Arb Waveform Generator mode can produce a single–modulated carrier or multiple–
modulated carriers. Each modulated carrier waveform must be calculated and generated before
it can be output; this signal generation occurs on the internal baseband generator. Once a
waveform has been created, it can be stored and recalled, which enables repeatable playback of
test signals. To learn more, refer to “Using the Arbitrary Waveform Generator” on page 379 .
— Custom Real-Time Waveform Generator mode can produce a single–modulated carrier or
multiple–modulated carriers. Each modulated carrier waveform must be calculated and
generated before it can be output; this signal generation occurs on the internal baseband
generator. Once a waveform has been created, it can be stored and recalled, which enables
repeatable playback of test signals. To learn more, refer to “Using the Arbitrary Waveform
Generator” on page 379 .
— Multitone mode produces up to 64 continuous wave signals (or tones). Like the Two Tone mode,
the frequency spacing between the signals and the amplitudes are adjustable. To learn more,
refer to “Creating a Custom Multitone Waveform” on page 412 .
— Two–tone mode produces two separate continuous wave signals (or tones). The frequency
spacing between the signals and the amplitudes are adjustable. To learn more, refer to Chapter
17, “Multitone and Two-Tone Waveforms (Option 430).” .
— Dual ARB mode is used to control the playback sequence of waveform segments that have been
written into the ARB memory located on the internal baseband generator. These waveforms can
be generated by the internal baseband generator using the Custom Arb Waveform Generator
mode, or downloaded through a remote interface into the ARB memory. To learn more, refer to
“Dual ARB Player” on page 187 .
