Advantest R4131D – 10kHz to 3.5GHz Spectrum Analyzer
Advantest R4131D – 10kHz to 3.5GHz Spectrum Analyzer,High-resolution spectrum analyzer covering a wide frequency range for RF signal analysis in communication and broadcasting.
The Advantest R4131D is a high-resolution spectrum analyzer covering 10 kHz to 3.5 GHz, engineered for RF signal characterization in communications, broadcasting, and R&D applications. It delivers precise amplitude and frequency measurements with ±1.0 dB accuracy across the -60 dBm to +20 dBm signal range, supported by a typical noise floor of -147 dBm (RBW 10 Hz) and greater than 70 dB dynamic range. The instrument features continuously variable frequency span, selectable resolution bandwidth from 10 Hz to 1 MHz, and video bandwidth control down to 1 Hz.
Multiple triggering modes - internal, line, external, and video - enable flexible measurement synchronization. Spurious response remains below -70 dBc for weak signals, while third-order intermodulation distortion is -70 dBc or better. Manual sweep times range from 10 ms to 1000 s with automatic sweep optimization.
The R4131D accepts 50 Ω RF input via Type N female connector and supports external triggering through BNC. Logarithmic and linear display modes with 1 dB step reference level adjustment (−70 dBm to +30 dBm) accommodate diverse measurement scenarios. Operating from 100 V to 240 V AC (50/60 Hz), the unit consumes approximately 70 VA and weighs 18 kg in a compact 428 × 195 × 485 mm footprint.
