Agilent/Keysight E1413A

The Agilent/Keysight E1413A is a single-width, C-size VXI data acquisition module that delivers high-speed analog-to-digital conversion for multi-channel measurement systems. It combines 16-bit resolution at up to 100 kHz sampling rate with a 64-channel FET multiplexer and on-board signal conditioning support via plug-on modules, enabling voltage, temperature, strain, and resistance measurements across mixed-signal applications.

Technical Specifications

• Analog-to-Digital Conversion: 16-bit resolution; 100,000 samples per second maximum


• Multiplexer: 64-channel FET configuration


• Data Buffer: 65,024 reading FIFO buffer (dual-ported, 64 kSa capacity); supports Circular Buffer or Block mode


• Data Format: IEEE 754 32-bit floating-point


• Current Value Table (CVT): 64 channel data registers in A24 address space for rapid display and control loop access


• Gain & Offset Correction: Per-channel correction at full scanning rate


• VXI Interface: A16 and A24 address space; SCPI and Compiled SCPI programming support

Key Features

• On-board calibration sources enable single-command, all-channel calibration


• Engineering Unit (EU) conversion performed at full speed on-board


• System wiring offset compensation per channel


• Signal Conditioning Plug-on (SCP) module support: accepts up to eight SCP modules in any mix


• Compatible SCP modules include E1501A through E1538A series


• Optional E1413-60001 Direct Input SCP card provides 8 additional channels

Typical Applications

• Real-time data acquisition in VXI-based test systems


• Multi-parameter monitoring requiring mixed-signal transducers


• High-speed scanning across distributed sensor arrays


• Temperature, strain, and resistance measurement networks


• PID loop feedback and control system integration

Compatibility & Integration Operates as a single VXI module within standard C-size slot architecture. Register-based interface sustains maximum acquisition rate; controllers such as the Radusis EPC-VII maintain full speed with dual E1413A configurations writing to disk at 900 KB/sec. Extended device addressing supports both A16 and A24 register spaces.
