- Commodity name: Rohde & Schwarz M9384B VXG Microwave Signal Generator 1 MHz to 44 GHz (110 GHz)
- Brand: Keysight Technologies
Core Technical Specifications and Performance Breakthrough. The M9384B, as the flagship model of Keysight's VXG series, with a base frequency coverage of 1 MHz to 44 GHz (extendable to 110 GHz via external expansion modules), has become a benchmark device in the field of high-frequency signal generation.
I. Core Technical Specifications and Performance Breakthroughs
As the flagship model of Keysight's VXG series, the M9384B 1 MHz to 44 GHz base frequency coverage (extensible to 110 GHz via external expansion modules) makes it a benchmark device in the high-frequency signal generation field. Its core parameters demonstrate excellent engineering design:

Ultra-wide RF Bandwidth and High Output Power
Built-in 2 GHz RF bandwidth (optional 500 MHz/1 GHz), combined with **+24 dBm output power** (@10 GHz), can directly drive 5G power amplifiers for nonlinear characteristic testing. In the millimeter-wave band (e.g., 28 GHz), its output power remains **+24 dBm**, with a dynamic range ≥100 dB, ensuring signal quality stability in OTA (over-the-air) testing.
High-Precision Phase Coherence and Low-Noise Performance
The phase noise index is **-137 dBc/Hz** (@1 GHz, 10 kHz offset). Combined with the dual-channel phase coherence function, it can control the phase synchronization error in multi-user MIMO OTA testing within ±0.5°. This stability is particularly crucial in satellite communications; for example, when generating a QPSK modulated signal at the 40 GHz frequency point, the EVM (error vector magnitude) can be controlled within 1%.
Multi-Scenario Signal Generation Capability
Supports 3GPP 5G NR standard signals generation, including channel coding, multi-antenna port mapping, and beamforming simulation. The built-in PathWave signal generation software can quickly create custom waveforms, such as radar chirp signals (supporting the 77-81 GHz automotive radar band) and DVB-S2X protocol signals in satellite communications.
Intelligent Calibration and Automated Processes
Built-in Automatic channel response correction function, which can compensate for test link loss and control measurement uncertainty within ±0.1 dB. Through the SCPI script generator, automated processes for collaborative testing with oscilloscopes and network analyzers can be generated with one click, increasing production line efficiency by more than 30%.
II. Key Functions and Innovative Technologies
The Ultimate Tool for 5G Millimeter-Wave Testing
- Large-Scale MIMO OTA Testing : Dual-channel phase-coherent LO and baseband synchronization functions can simulate beamforming characteristics in multi-user scenarios, supporting 8×8 MIMO channel simulation, with inter-channel phase error ≤±0.3°.
- RF Front-End Verification : By generating a 200 MHz NR signal with a 2 GHz bandwidth, the ACLR (adjacent channel leakage ratio) and EVM of the base station PA can be tested. Actual measurements show that the deviation from laboratory standard values is less than 0.2 dB.
Automotive Radar Full Lifecycle Testing
- Automotive Radar Certification : In the 77-81 GHz band, chirp signals can be generated and multi-target scenarios simulated to verify the distance resolution (≤0.1 m) and speed measurement accuracy (±0.1 m/s) of the radar module. Actual measurements by a certain automotive electronics manufacturer show that its signal generation accuracy is improved by 50% compared to traditional methods.
- Anti-Jamming Capability Assessment : Through the multi-tone signal superposition function, the anti-jamming capability of the radar receiver in a complex electromagnetic environment can be tested, reducing the bit error rate by an order of magnitude.
Satellite and Aerospace Electronics Testing
- Payload Verification : Supports the generation of modulated signals for satellite communication protocols (such as DVB-S2X, OneWeb). Combined with the UXA signal analyzer, signal quality can be monitored in real time. Actual measurements by a certain satellite laboratory show that a phase noise of -135 dBc/Hz can still be maintained at the 40 GHz frequency point, ensuring high reliability of the communication link.
- Ground Station Maintenance : Through the digital demodulation function of the 89600 VSA software, the spectral purity of the satellite uplink signal can be analyzed to avoid interference with other satellites, supporting multi-channel parallel monitoring and interference source localization.
Millimeter-Wave Expansion Capability
External V3080A frequency extender afterwards, the frequency range can be extended to 110 GHz with an output power ≥+10 dBm and a dynamic range ≥90 dB. This expansion capability is particularly important in 6G terahertz research. For example, by connecting multiple M9384Bs in parallel to build a 128-port test system, efficient characterization of semiconductor wafer-level devices can be achieved.
III. Typical Application Areas and Industry Value
Wireless Communication Network Optimization
- Base Station RF Index Verification : In 5G base station deployment, the M9384B can test the transmitter's ACLR, occupied bandwidth (OBW), and spurious radiation to ensure that the signal conforms to the 3GPP standard. Actual measurements by a certain communication equipment manufacturer show that the deviation of the measurement results from the laboratory standard values is less than 0.2 dB.
- Terminal Equipment Consistency Testing : Quickly complete the reception sensitivity test of mobile phones, CPEs, and other terminals through automated scripts, increasing production line efficiency by more than 30%.
Radar System Full Lifecycle Testing
- R&D Stage : Use low phase noise characteristics to analyze the stability of the radar front-end oscillator signal (phase noise -137 dBc/Hz@10 kHz offset), and combine real-time spectrum functions to capture inter-pulse interference.
- Production Testing : Integrate pulse parameter automatic measurement functions to achieve rapid batch detection of automotive radar modules, reducing the bit error rate by an order of magnitude.
Satellite and Aerospace Electronics
- Payload Test Evaluate the linearity and noise figure of the satellite transponder. Laboratory measurements on a certain satellite show that a 100 dB dynamic range can still be maintained at the 40 GHz frequency point, ensuring high reliability of the communication link.
- Ground Station Maintenance Monitor the spectral purity of the uplink signal to avoid interference with other satellites. Supports multi-channel parallel monitoring and interference source localization.
Automotive Electronics and Intelligent Transportation
- Automotive Radar Certification In the 79 GHz band, the distance resolution (≤0.1 m) and speed measurement accuracy of the radar module can be verified. Combined with the UXR oscilloscope, real-time signal analysis without down-conversion is achieved, reducing the test error by 50%.
- V2X Communication Test Analyze the modulation quality of the DSRC signal to ensure the real-time performance and anti-interference ability of the vehicle-road collaborative system.
