R3465

The Advantest R3465 is a modulation spectrum analyzer designed for evaluating digital mobile communication systems. Operating across a frequency range from 9 kHz to 8 GHz, it integrates standard spectrum analyzer capabilities with digital transmission test functions, including modulation accuracy and transmission speed measurements. Utilizing Direct Digital Synthesizer (DDS) technology and a high-speed settling synthesizer, it supports standard preset modes for PHS, PDC, and NADC systems, alongside optional analysis for GSM, DECT, and CDMA.
