Keysight / Agilent / HP E1413B High-Speed 64-Channel Scanning A/D Converter

The Keysight E1413B is a high-speed 64-channel scanning A/D converter module designed for VXIbus-based automated test equipment and data logging systems. This C-size, single-slot module delivers up to 100,000 samples per second across all channels, with output data formatted as IEEE 754 32-bit floating-point values in either Engineering Units or raw voltage. A 65,024-reading FIFO buffer enables continuous data streaming, while the Current Value Table provides immediate access to the latest reading from each channel without halting acquisition.
