Signal Generator Overview

Modes of Operation

Modes of Operation

All PSG signal generator models can be used in CW mode:

•CW mode produces a single carrier signal.

—If you have an E8247C PSG CW signal generator, you can produce a CW single carrier signal without modulation.

—If you have an E8257C PSG analog signal generator, you can produce a CW single carrier signal without modulation, or you can add AM, FM, Φ M, or Pulse modulation to produce a single carrier

modulated signal; some of these modulations can be used together.

—If you have an E8267C PSG vector signal generator, you can produce a CW single carrier signal without modulation, or you can add AM, FM, Φ M, Pulse, or I/Q modulation to produce a single

carrier modulated signal; some of these modulations can be used together.

In addition to CW and analog mode, all of the following modes are also available to the E8267C PSG vector signal generator:

•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 (Option 002/602). Once a waveform has been created, it can be stored and recalled which enables repeatable playback of test signals. To learn more, refer to “Custom Arb Waveform Generator” on page 119.

•Custom Real Time I/Q Baseband mode produces a single carrier, but it can be modulated with real time data that allows real time control over all of the parameters that affect the signal. The single carrier signal that is produced can be modified by applying various data patterns, filters, symbol rates, modulation types, and burst shapes. To learn more, refer to “Custom Real Time I/Q Baseband” on page 145.

•Two Tone mode produces two separate carrier signals without any kind of modulation; the frequency spacing between the two carrier signals is adjustable as well as the amplitude of both carriers. To learn more, refer to “Two-Tone Waveform Generator” on page 179.

•Multitone mode produces any number of carrier signals without any kind of modulation; like Two Tone mode, the frequency spacing between all carrier signals is adjustable as well as the amplitude of all carriers. To learn more, refer to “Multitone Waveform Generator” on page 169.

•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 (Option 002/602). These waveforms can be generated using the internal baseband generator, in Custom Arb Waveform Generator mode, or downloaded through a remote interface into the ARB memory. To learn more, refer to “Dual Arbitrary Waveform Generator” on page 87.
