Advantest R3264 9kHz to 3.5GHz Spectrum Analyzer

The Advantest R3264 is a spectrum analyzer operating from 9 kHz to 3.5 GHz, engineered for signal analysis in laboratory and field environments. It delivers dynamic range of 70 dB or better and typical noise performance of -146 dBm/Hz at 2 GHz, making it suitable for EMC measurements, component testing, and communication system validation. The R3264 combines high-resolution analysis with practical measurement functions including ACP, occupied bandwidth, harmonics, and phase noise characterization.
