Keysight / Agilent / HP E1413A High-Speed 64-Channel Scanning A/D Converter

The Keysight E1413A is a high-speed, 64-channel scanning A/D converter module designed for VXIbus-based data acquisition systems. This single-slot, C-size VXI module delivers 16-bit resolution across 64 analog input channels with scanning rates up to 100,000 samples/second, making it ideal for automated test equipment, process monitoring, and multi-channel measurement applications requiring rapid sequential or simultaneous signal capture.

– Technical Specifications

• Analog Input Channels: 64
• A/D Resolution: 16-bit
• Scanning Rate: Up to 100,000 samples/second
• Data Format: IEEE 754, 32-bit floating-point
• Data Buffer: 65,024 reading FIFO buffer
• Current Value Table (CVT): Stores latest reading from each of 64 channels for rapid access
• Scan Lists: Four scan lists, each holding up to 1,024 channel assignments
• “List of Lists” Capability: References scan lists up to 1,024 times for complex scanning sequences
• Form Factor: Single Slot, C-Size VXI Module

– Key Features

• Autoranging capability maintains accuracy specifications at speed
• Onboard Engineering Units (EU) conversion; readings returned as input voltage or converted to engineering units
• Onboard calibration sources for single-command, all-channel calibration
• System wiring offset compensation
• Signal Conditioning Plug-on (SCP) module support—up to eight SCP modules per module
• SCPI and Compiled SCPI command language accessibility
• Resistance measurement capability via two channels with current source and voltage input SCP modules

– Typical Applications

• Automated test equipment (ATE) requiring multi-channel data acquisition
• Process monitoring with high-speed sequential measurements
• Research applications demanding rapid acquisition of numerous data points across multiple analog signals

– Compatibility & Integration

The E1413A interfaces with a comprehensive range of Signal Conditioning Plug-on modules (E1501A through E1518A, and E1531A through E1538A) and is compatible with interconnect modules such as the Keysight 84000-61151. Terminal blocks are sold separately, including the Keysight E1413-66510 Terminal Block PCA Assembly and Keysight E1413-80011 QUIC Terminal Block. The module integrates into VXIbus systems and has been historically deployed with controllers such as the Radusis EPC-VII for high-speed disk-based data acquisition.
