Keysight / Agilent / HP E1511A 4-Channel Transient Strain SCP Module

The Keysight/Agilent/HP E1511A is a 4-channel transient strain Signal Conditioning Pod (SCP) module for VXIbus-based data acquisition systems. It delivers integrated signal conditioning for strain gauge measurements in dynamic testing environments where precise transient event capture is essential. The module combines strain completion circuitry, excitation voltages, programmable filtering, and sample-and-hold functionality to minimize channel skew during simultaneous four-channel sampling.

## Technical Specifications

• **Channels:** 4
• **Architecture:** Signal Conditioning Plug-on (SCP) module
• **Measurement Type:** Transient strain
• **Signal Conditioning:** Strain completion circuitry, excitation voltages, programmable filter, sample-and-hold circuitry with simultaneous sampling across all channels

## Key Features

• Simultaneous sampling of all four channels minimizes temporal skew in strain measurements
• Programmable filter enables frequency-selective signal conditioning tailored to specific test requirements
• Integrated excitation voltage supply eliminates external instrumentation for strain bridge completion
• Sample-and-hold circuitry ensures synchronized data capture in transient and dynamic test scenarios

## Typical Applications

• Dynamic strain measurement and transient event capture
• Structural health monitoring and vibration analysis
• Stress and strain analysis in dynamic material testing
• Material characterization under dynamic loads

## Compatibility & Integration

The E1511A interfaces with Keysight/Agilent VXI mainframes through compatible VXI cards. The E1313 VXI card accommodates up to four SCP modules; cards E1413, E1415, E1419, and E1422 each support up to eight SCP modules. As part of Agilent’s SCP family, the module integrates with scanning A/D converters on VXI cards to provide application-specific signal conditioning.
