Keysight / Agilent / HP E1513A 8-Channel Fixed Attenuator / Fixed Filter SCP Module

The Keysight E1513A is an 8-channel signal conditioning plug-on (SCP) module that combines fixed attenuation and low-pass filtering for precision signal conditioning within VXI-based instrumentation systems. Each channel provides divide-by-16 attenuation with integrated input over-voltage protection and a 7 Hz, 3 dB cutoff low-pass filter. The module installs directly onto compatible VXI cards, enabling compact multi-channel signal conditioning for data acquisition and test applications requiring simultaneous attenuation and bandwidth limiting across multiple signal paths.

## Technical Specifications

• **Channels:** 8
• **Attenuation:** Divide-by-16 fixed
• **Low-Pass Filter Cutoff:** 7 Hz at 3 dB
• **Input Protection:** Over-voltage protection included
• **Form Factor:** Signal Conditioning Plug-on (SCP) Module

## Key Features

• Fixed divide-by-16 attenuator eliminates the need for programmable control and settles instantly
• 7 Hz low-pass filter removes high-frequency noise and aliases before signal conditioning
• Input over-voltage protection safeguards sensitive downstream instrumentation
• Eight independent channels enable parallel signal conditioning without channel crosstalk concerns
• Compact SCP form factor minimizes mainframe footprint while maximizing channel density

## Typical Applications

• Multi-channel analog signal conditioning in data acquisition systems
• Pre-filtering and attenuation for precision measurement instrumentation
• Noise reduction and amplitude scaling in sensor signal chains
• VXI-based test systems requiring standardized signal conditioning modules
