Two-tone personality

Two-tone signals are the most widely used for analyzing nonlinear distortion. The PSG

two-tone personality provides a streamlined user interface to quickly generate two tones

with equal power and equal phase initialization, Figure 10. The signal parameters that can

be adjusted in this application are a subset of those found in the multitone personality. The

minimized feature set is intended to simplify the generation of basic two-tone

signals so that common measurements can be made efficiently. The wide RF modulation

bandwidth of the internal baseband generator allows tone spacing up to 80 MHz.

A. Set carrier frequency

• 250 kHz to 20 GHz

B. Set the amplitude of the PSG signal

• power is divided equally into each tone

C. Set relative tone spacing

• 100 Hz to 80 MHz

D. Place tones symmetrically around carrier frequency

or offset to mask carrier feed through
