Signal Studio for Enhanced Multitone

There is optional software for the E8267C PSG vector signal generator to improve the signal

quality of two-tone and multitone test signals. Signal Studio for enhanced multitone,

Option 408 for the E8267C, significantly improves the IMD suppression, RF flatness,

image suppression, and carrier feed through performance of multitone test signals

generated by the PSG. The improved signal quality is achieved by applying pre-distortion

to the I/Q waveform based on an iterative correction algorithm. Refer to the Signal Studio

for Enhanced Multitone Technical Overview (publication number 5988-5639EN) for

additional information on this application.
