Description
Product Overview
The Agilent E1413C is a high-density digital I/O module for the VXIbus platform, engineered to deliver precision control and monitoring in automated test systems. As part of Agilent Technologies’ (now Keysight) renowned VXI instrument family, this 64-channel module provides flexible digital signal interfacing with programmable voltage thresholds. The Agilent E1413C supports both TTL (0–5V) and CMOS (0–12V) logic families, enabling seamless integration with industrial controllers, PLCs, and custom test fixtures. Its per-channel configurability allows mixed input/output assignments, while onboard pattern generation simplifies stimulus-response testing. Designed for reliability in manufacturing test racks, the E1413C leverages VXI’s deterministic data transfer to achieve 10 MHz signal rates with nanosecond timing precision. For aerospace, automotive, and semiconductor validation labs, this module remains a cost-effective solution for legacy systems requiring robust digital I/O expansion.

Agilent E1413C
Main Features and Advantages
Dynamic channel configuration: Each of the 64 channels on the Agilent E1413C operates independently as input, output, or bidirectional port, with programmable pull-up/pull-down resistors. This eliminates external signal conditioning for mixed-voltage systems.
Deterministic timing: Hardware pattern sequencing supports 25 ns edge placement accuracy, critical for synchronized multi-instrument tests. Integrated glitch detection captures transient errors down to 50 ns.
VXIbus integration: Slot 0 controller compatibility enables direct memory access (A32/D32) for low-latency data streaming. The module supports all VXI trigger lines, facilitating complex multi-module synchronization without external cabling.
Legacy software support: Native drivers for Agilent VEE, LabVIEW, and C/C++ simplify integration into existing test executives. The Agilent E1413C includes built-in self-test (BIST) routines for field diagnostics.
Application Field
The Agilent E1413C excels in automated test equipment (ATE) requiring high-channel-count digital control. In semiconductor production, it validates memory devices by applying test patterns at speed grades up to 10 MHz. Automotive electronics labs use it for ECU functional testing, simulating sensor inputs and monitoring actuator outputs.
Aerospace applications include flight control hardware-in-loop (HIL) simulation, where the module injects failure scenarios via fault insertion units. Industrial automation leverages its 12V CMOS capability to interface directly with PLC digital cards. The Agilent E1413C also serves military radio testing, emulating control signals for legacy communication systems.
