Agilent M9381A-F06 PXIe Vector Signal Generator
The M9381A-F06 from Agilent is a PXIe Vector Signal Generator for RF test. It covers a continuous frequency range from 1 MHz to 6 GHz for wideband applications and integrates four PXIe modules that operate as a single coherent RF generation platform. This unit uses peer to peer PXIe backplane triggering for deterministic synchronization within supported chassis groups. The M9300A supplies 10 MHz and 100 MHz signals to the M9381A-F06 system. It accepts external reference inputs from 1 MHz to 110 MHz across an input power range. The module distributes 100 MHz outputs that exceed 12 dBm for stable reference distribution, additional 10 MHz and OCXO outputs provide precise time-base signals for industrial automation tasks.
The synthesizer in the M9381A-F06 configuration generates local oscillator frequencies to 6 GHz. Its RF LO outputs span from 187.5 MHz to 6 GHz with power from minus ten dBm. The synthesizer locks to the 100 MHz reference and delivers low phase noise at key offsets. External trigger inputs and list end outputs support programmed frequency switching during automated test sequences. The M9311A PXIe digital modulator processes baseband IQ data for the M9381A-F06 architecture. It accepts an LO input from the synthesizer between 187.5 MHz and 6 GHz at modest power levels. The modulator produces a vector modulated RF output from 187.5 MHz to 6 GHz for up-conversion. Trigger connections manage pulse RF blanking and synchronization to downstream RF stages during time critical testing. Its source output module provides the final RF output path and accepts RF from the modulator between 100 MHz and 6 GHz at controlled drive levels. Its RF output frequency range extends from 1 MHz to 6 GHz with fine amplitude resolution.
The standard output power of the device spans -120 dBm to 10 dBm for stimulus generation. The unit’s Integrated 100 MHz reference routing between modules maintains phase coherent operation throughout the M9381A-F06 system. Its dedicated trigger and synchronization connectors use 3.3 V logic into 50-ohm terminations. Modules share 10 MHz reference connections so external instruments can lock to the same time-base. The M9381A-F06 module’s robust mechanical design supports continuous operation with slot blockers that maintain airflow around each module. Its system level initialization through the soft front panel verifies hardware status and executes internal self-tests.
