The Advantest R3561L is a CDMA test source unit engineered for signal generation and verification of CDMA mobile communication devices, base stations, and mobile units operating in cellular and PCS frequency bands. It operates in conjunction with Advantest R3465 or R3463 Modulation Spectrum Analyzers—requiring optional CDMA Test Control (OPT. 09)—and delivers precise, standards-compliant waveforms essential for performance and compliance validation.

– Compatibility & Integration
Primary operation requires Advantest R3465 or R3463 Modulation Spectrum Analyzers with CDMA Test Control Option (OPT. 09) installed for integrated control. Can also interface with the R3267 Spectrum Analyzer. Horizontal orientation required during operation and storage; maintain 10 centimeters minimum clearance around air vents.
