Rohde & Schwarz FSPN Phase Noise Analyzer: A Benchmark Device for High-Frequency Signal Quality Analysis
I. Product Positioning and Core Value
- Ultra-wide Frequency Coverage The basic model FSPN26 supports 1 MHz to 26.5 GHz, and the extended model FSPN50 reaches 50 GHz, covering 5G millimeter wave (28 GHz/39 GHz), automotive radar (77 GHz/79 GHz), and terahertz bands (above 100 GHz), meeting the needs of 6G pre-research, satellite communication, and industrial testing.
- Ultra-high Sensitivity Measurement Using real-time cross-correlation technology, the typical phase noise value at 1 GHz carrier @10 kHz offset is -172 dBc/Hz This is a 10-20 dB improvement over traditional methods, allowing for precise characterization of the phase stability of low-noise oscillators (such as OCXO, DRO).
- Integrated Testing Capability Built-in ultra-low noise DC source (3 independent outputs), supports automatic testing of VCO characteristics (frequency/power/current changes with voltage), and can simultaneously measure amplitude noise (AM Noise), simplifying the testing process.
II. Core Technological Breakthroughs
- Sensitivity Improvement Through dual-channel independent down-conversion and hardware cross-correlation engine, random noise interference is eliminated. At 26.5 GHz, the phase noise sensitivity is improved by more than 10 dB compared to competitors. For example, at 10 GHz carrier @10 kHz offset, the typical phase noise value of FSPN26 is -153 dBc/Hz which is superior to Keysight E5052B's -148 dBc/Hz 。
- Measurement Speed Optimization In production scenarios, only 2-3 cross-correlations are needed to complete high-quality VCO testing. In R&D scenarios, by increasing the number of cross-correlations (up to 100 times), femtosecond-level jitter analysis can be achieved, balancing efficiency and accuracy.
- Transient Measurement Simultaneously monitors changes in frequency, phase, and power over time, supporting microsecond-level resolution, and can capture nonlinear distortion of radar chirp signals or burst interference in satellite communications.
- Pulse Signal Analysis One-click measurement of the phase noise of pulse sources, supporting precise characterization of pulse width, duty cycle, and rise/fall time, suitable for military radar and industrial pulsed laser testing.
- VCO Characteristic Automation Built-in 3-channel ultra-low noise DC source (0-20 V, ±10 mA), automatically scans the tuning voltage and generates VCO characteristic curves (such as frequency sensitivity, power fluctuation), reducing manual operation errors.
- Graphical User Interface The 12.1-inch touchscreen supports multi-window display, allowing simultaneous viewing of phase noise, jitter, and spectrum data, and one-click generation of test reports conforming to 3GPP and IEEE standards.
- Software-Defined Functionality Activate higher frequency ranges (such as FSPN50 extended to 50 GHz) or upgrade jitter analysis software through options to flexibly adapt to different testing needs.
- Automated Integration Supports SCPI commands and LAN remote control, and can be seamlessly integrated into ATE systems to improve production line testing efficiency.
III. Typical Application Scenarios
- Millimeter-wave PA Verification Measures the phase noise and EVM (error vector magnitude) of 28 GHz/39 GHz 5G NR signals, verifies the linearity of base station power amplifiers, and supports the 3GPP TS 38.141 standard.
- 6G Terahertz R&D Extends to 110 GHz through the 11970 series harmonic mixer to analyze the phase noise and modulation accuracy of terahertz band signals, assisting in the pre-research of 6G ultra-high-speed communication systems.
- 77 GHz FMCW Signal Analysis Measures the linearity and phase noise of automotive radar to ensure the target recognition accuracy of ADAS systems and meet the ISO 26262 functional safety requirements.
- Terahertz Non-destructive Testing In conjunction with a terahertz mixer, analyzes defects in the hot-melt joints of polyethylene pipes to improve the efficiency and accuracy of industrial testing.
- Ka-band Signal Verification Tests the phase noise and frequency stability of satellite communication equipment to ensure the reliability of the satellite-ground link and support high-throughput satellite (HTS) services.
- Radar Anti-jamming Optimization Real-time monitoring of the spectral purity of radar signals, suppressing the influence of stray signals on the navigation system, and improving the anti-jamming capability of military radar.
