Keysight / Agilent / HP E1430A VXI 10 MSa/s 23-bit Digitizer

The Keysight E1430A is a C-size VXI digitizer module delivering 10 MSa/s sampling with 23-bit resolution for precision measurement and signal analysis. This register-based, one-slot instrument combines a two-pass digitizer architecture with DSP-based real-time digital filtering, programmable gain conditioning, and large FIFO memory to capture transients, analyze spectra, digitize intermediate frequencies, and record complex waveforms across demanding applications. ## Technical Specifications • Sampling Rate: 10 MSa/s maximum • Resolution: 23-bit raw • Dynamic Range: 18 bits (110 dBFS) distortion-free, spur-free dynamic range with dithering and on-the-fly distortion correction • Noise Density: −136 dBfs/Hz • Noise Figure: 15 dB • Input Impedance: 50 ohms • Input Range: +28 dBm to −32 dBm, programmable in 6 dB steps • Anti-Alias Filters: Built-in; 4 MHz maximum information bandwidth; selectable bypass for fastest rise times • Digital Filters: Multistage, programmable with decimation; bandwidths from 4 MHz to 0.24 Hz in octave steps • Digital Local Oscillator: Tunable for signal-centric filtering and unwanted signal rejection • Memory: 8 MB high-speed FIFO for transient capture and block-mode data transfer • Signal Conditioning: Flexible input signal conditioning included • Local Bus Data Transfer: 40 Mbytes/sec ## Key Features • Two-pass sub-ranging digitizer architecture • Programmable gain in 6 dB steps across wide dynamic range • DSP-based real-time filtering with independently tunable digital LO • Octave-step digital filter bandwidth control for noise optimization • Large FIFO memory supporting continuous acquisition and transient recording • Standard VXI data path and high-speed Local Bus connectivity ## Typical Applications • Spectrum analysis and IF digitization • Transient capture and waveform recording • High-resolution time-domain measurements • Low-noise signal conditioning and filtering ## Compatibility & Integration VXI-based architecture with VXIplug&play compatibility.
