Anritsu developed the MG3641A Synthesized Signal Generators to meet the need for higher signal purity at higher frequencies. The MG3641A covers the frequency range of 125 kHz to 1040 MHz with non-harmonic spurious of only 100 dBc. A full lineup of easy-to-use versatile functions in a compact cabinet makes the MG3641A an essential tool for high-frequency measurement. Anritsu synthesizer technology permits frequencies to be set with a resolution of 0.01 Hz across the full frequency range. A unique low-noise YIG oscillator produces a high-purity signal with SSB phase noise of better than -130 dBc/Hz (1 GHz, 20 kHz offset) making this signal generator excellent for radio receiver interference testing and as sources for reference signals.
