High signal purity and low phase noise

The 9640A generates a pure sinusoidal signal with extremely low harmonics, spurious and residual modulations. This ensures that level accuracy will be maintained when you make measurements with wideband or narrow band detectors, or when the 9640A is intercomparing peak and RMS sensing instruments. You will avoid differences between the wideband/ narrow band and peak/RMS sensors, without requiring additional filters.
