1. The IFR2026 synthesizer generates a two-tone signal (F1 = 180 kHz, F2 = 280 kHz), each tone having the same

amplitude. The HP3585 spectrum analyzer measures the intermodulation products as a function of the output voltage. The

generator and the spectrum analyzer are phase locked for better accuracy.
