Agilent Keysight E1413C | 64-Channel VXI Scanning A/D Converter

Description

Core Product Summary

The Agilent Keysight E1413C is a 64-channel, high-speed scanning analog-to-digital converter in a single-width, C-size VXIbus module. It multiplexes 64 input channels to a 16-bit A/D converter and provides a maximum aggregate scanning rate of 100,000 readings per second.

The E1413C converts measurements into engineering units and stores results in a 65,024-reading FIFO buffer, while a Current Value Table retains the latest reading for each channel. Signal conditioning is provided by optional Signal Conditioning Plug-on (SCP) modules; an SCP is required for every input. The module supports DC-voltage, temperature, resistance, and strain measurements and is operated through its register-based VXI interface.

Key Technical Specifications

Detailed Product Overview

The Agilent Keysight E1413C is a C-size VXIbus data-acquisition module designed for high-speed, multichannel measurement in test systems and industrial data-acquisition architectures. Its 64 differential FET-multiplexed inputs share one 16-bit A/D converter, allowing the module to scan a configurable list of channels rather than digitize every channel continuously.

Scanning is the module’s measurement method. A scan list can contain from 2 to 64 channels, or from 3 channels when a Sample and Hold SCP is installed, and channels may be placed in any order. The maximum aggregate rate is 100,000 readings per second; therefore, the effective rate for each channel depends directly on the number of channels included in the scan. For example, a 64-channel scan produces approximately 1.56 k readings per second per channel, while a 16-channel scan produces 6.25 k readings per second per channel.

The E1413C performs engineering-unit conversion for DC voltage, temperature, resistance, and strain measurements. It supports temperature measurement using configured transducer characteristics, including a 5000-ohm thermistor and 100-ohm RTD types 385 and 392. Custom calibrated temperature transducers can also be handled through the module’s diagnostic SCPI command structure.

Signal conditioning is modular. Each input requires an SCP, and up to eight SCPs can be installed inside the E1413C. Most SCPs condition eight channels, enabling configurations such as direct input, 10 Hz low-pass filtering, fixed gain and filtering per channel, attenuation, and sample-and-hold input. The available measurement ranges are determined by the installed SCP; the base module provides five DC-voltage ranges from 0.0625 V to 16 V.

Acquired readings are routed to the 65,024-reading FIFO buffer for high-speed transfer to the controller. The Current Value Table provides immediate access to the most recent reading from each of the 64 channels, supporting online monitoring while a scan is running. The module also performs on-board data reduction and high/low limit checking.

As a register-based VXI instrument, the E1413C does not support the VXIbus word-serial protocol. Integration therefore requires a controller and software environment compatible with register-based VXI modules and the module’s SCPI command set. The module requires one C-size VXI slot and must be installed in a compatible VXI mainframe with adequate power allocation for the E1413C and its installed SCPs.

Yes. A Signal Conditioning Plug-on module is required for every input, and up to eight SCPs can be installed in the E1413C.

How fast can it scan 64 channels?
At the maximum aggregate rate of 100,000 readings per second, a 64-channel scan provides approximately 1.56 k readings per second per channel.

What VXI slot does it require?
The E1413C is a C-size, single-width VXI module and requires one C-size slot in a compatible VXI mainframe.

Does it support word-serial VXI communication?
No. The E1413C is a register-based module and does not support the VXIbus word-serial protocol.

How are readings stored?
Readings are placed in a 65,024-reading FIFO buffer, while the Current Value Table stores the latest reading for each of the 64 channels.
