The M9389A is a PXIe Vector Network Analyzer Source module designed exclusively as a component within the Keysight M9485A PXIe multiport vector network analyzer system. This discontinued but supported product delivers RF signal generation from 1 MHz to 6 GHz at +19 dBm output power, functioning as the signal source for multiport VNA measurements. The M9389A comprises two integrated PXIe modules—the M9310A source output and M9309A synthesizer—and operates under control of the M9485A software front panel.
Technical Specifications
• Frequency Range: 1 MHz to 6 GHz

• Operating Temperature (Controlled): Module ≤ 55 °C at 20–30 °C ambient
• Operating Temperature (Full Range): Module ≤ 75 °C at 0–55 °C ambient
• Thermal Stabilization: 45-minute warm-up required after 2-hour minimum storage within full temperature range
– Key Features
• Amplitude repeatability maintained across the 1 MHz–6 GHz frequency range
• Output power normalized response performance data documented
• Dual-module architecture integrating source and synthesizer functions
• Operates within M9485A multiport measurement framework supporting up to 24 ports across dual chassis
• Temperature-controlled operation optimized for phase coherence in multi-channel configurations
– Typical Applications
• Multiport network analysis and characterization
• Multi-channel phase-coherent RF measurements
• System-level VNA testing within PXIe platforms
– Compatibility & Integration
The M9389A is not a standalone instrument; it functions exclusively as a source module within the M9485A VNA system. Integration requires proper chassis thermal management: deploy slot blockers and EMC filler panels in empty slots, and set chassis fan to high speed when ambient temperature exceeds 45 °C. Associated modules include the M9310A (source output) and M9309A (synthesizer).
