Agilent/Keysight E1413C

The Agilent/Keysight E1413C is a 16-bit, 64-channel differential scanning ADC module housed in a single VXI C-size slot. It delivers up to 100,000 samples/second across configurable channel lists and integrates a 65,024-sample dual-ported FIFO buffer for sustained high-speed data transfer. The module accepts up to eight Signal Conditioning Plug-on (SCP) modules, enabling DC voltage, temperature, resistance, and strain measurements across input ranges from 4 mV to 16 V (expandable to 60 V with attenuator SCP). Autoranging gains of ×1, ×4, ×16, ×64, and ×256 provide measurement flexibility. Data output is IEEE 754 32-bit floating-point, either as engineering units or raw input voltage.
