Functions
Electronic circuit module for high-performance signal processing in RF spectrum analyzers. Performs analog-to-digital conversion of intermediate frequency (IF) signals, digital filtering, decimation, and complex signal processing. Enables precise frequency analysis, phase measurements, and digital demodulation. Incorporates FPGA/DSP architecture for real-time signal processing, frequency synthesis, and digital down-conversion. Interfaces with RF front-end components and main processor board via high-speed digital buses. Used in spectrum analysis, signal intelligence, communications testing, and radar systems verification applications.
Platforms
A board-level assembly designed for internal installation within PSA Series Spectrum Analyzers (e.g., E4440A, E4443A). It interfaces with the instrument's main backplane, RF front-end, and DSP modules via board-to-board connectors. The assembly's primary function is the high-speed digitization of the final analog Intermediate Frequency (IF) signal using an ADC, followed by digital down-conversion and filtering. It is a core component enabling the host instrument's advanced RF signal analysis, spectral measurement, and digital demodulation applications.
Applications
High-frequency signal processing and conditioning in spectrum analyzers and network analyzers for RF and microwave measurements. Provides digital intermediate frequency conversion, filtering, and signal conditioning for accurate spectral analysis, EMI/EMC testing, and communication system characterization. Enables precise frequency domain measurements, spurious signal detection, and phase noise analysis in laboratory and production test environments. Supports wide bandwidth signal analysis for radar, satellite communication, and wireless device testing applications requiring high dynamic range and measurement accuracy.
Accessories
E4440A mainframe, backplane, power supply, and CPU board are required for operation. Internal interfaces consist of proprietary high-density multi-pin board-to-board connectors for digital IF data transfer, power distribution, and control signaling within the PSA system. No external user-accessible interfaces.
Interfaces
J1 is a multi-pin board-to-board backplane connector for digital data and control interfacing with the A12 Digital Processor. J4 is an SMP female coaxial connector for the 10.7 MHz IF input from the A6 Analog IF/Detector assembly. Additional multi-pin headers provide power and control interconnections with other internal modules within the PSA series chassis.
Specifications
Digital IF Assembly designed for integration into spectrum analyzers, providing intermediate frequency digital signal processing functionality. Operates within the instrument’s modular hardware platform, interfacing via high-speed digital connections and control buses to main processing units. Enables enhanced signal demodulation, filtering, and analysis capabilities, supporting precise frequency measurements and complex modulation formats for RF and microwave signal characterization in laboratory and field test environments.
