1. Note on intermodulation products:
The IFR2026 synthesizer generates a two tone signal (F1 = 180 kHz, F2 = 280 kHz); each tone has the same amplitude
level.
The HP3585 spectrum analyzer measures the intermodulation products function of the output voltage. The generator and
the spectrum analyzer are phase locked for precision considerations.
