Agilent/Keysight M9377A

The Keysight M9377A is a PXIe direct access receiver module engineered as a single-port component within multiport Vector Network Analyzer systems. It integrates into the M9485A PXIe Multiport VNA and operates across 50 MHz to 9 GHz with 100 MHz modulation bandwidth. This two-slot PXIe module delivers dynamic accuracy of ±0.13 dB at -80 dBm (with 0 dB attenuator and -30 dBm reference) and achieves a noise floor of -145 dBm from 50 MHz to 6 GHz.

– Technical Specifications

• Frequency Range: 50 MHz to 9 GHz
• Modulation Bandwidth: 100 MHz
• Dynamic Accuracy: ±0.13 dB @ -80 dBm (Reference/Test Attenuator 0 dB, Reference = -30 dBm)
• Noise Floor: -145 dBm @ 50 MHz to 6 GHz
• Form Factor: PXIe (two-slot occupancy)

– Key Features

• Single-port receiver architecture for direct signal access
• Integrated PXIe module—no external instruments required for receiver function
• Low noise performance suitable for sensitive measurement applications
• Specified dynamic range enables detection of weak signals in presence of strong carriers

– Typical Applications

• Multi-port S-parameter characterization in modular VNA systems
• Component and device measurement requiring distributed receiver architecture
• Integrated receiver functionality within PXI-based test racks

– Compatibility & Integration

The M9377A functions as a core receiver module within the M9485A PXIe Multiport Vector Network Analyzer platform. It requires a PXIe chassis and operates within the M937xA product family, extending network analysis capability into modular instrumentation form factors.
