Because the signals are implemented digitally using the internal baseband generator,

relative tone spacing, relative tone power, and initial tone phase can now be controlled

with digital precision. Using the Agilent vector solution, these parameters are easily and

precisely set from the instrument front panel or remotely using the GPIB or LAN interface.

This technique even provides the ability to select fixed or random phase initialization

when configuring the test signal. This feature, combined with the internal baseband

generator sequencing capability, enables efficient testing with a series of random

phase sets. Figure 9 shows the vector test setup to perform a two-tone or multitone

IMD measurement.
