The Keysight E1421-66501 is a VXI 6-slot backplane module engineered for the E1421B C-size mainframe. This module delivers the essential backplane infrastructure required for a 6-slot VXI system, establishing connectivity and signal integrity across installed modules. It complies fully with VXIbus specifications and integrates proven thermal management and serviceability features.
## Technical Specifications
• **Model:** E1421-66501
• **Product Type:** VXI Backplane Module
• **Form Factor:** C-size
• **Slot Count:** 6 slots
• **Mainframe Compatibility:** E1421B VXI mainframe
• **VXIbus Compliance:** Meets VXIbus Specification standard
• **Power Input:** 100–240 VAC
## Key Features
**Connectivity Architecture**
The backplane utilizes dual VXIbus connector pairs for comprehensive signal distribution. The P1 connector carries the 16-bit data transfer bus, 24-bit addressing, and power voltages (+5V, +/–12V). The P2 connector expands the data interface to 32-bit, adds a 10 MHz clock bus, analog sumbus, TTL and ECL trigger buses, and supplies additional power rails (–5.2V, –2V, +/–24V).
**Insertion & Extraction**
Injector surface rails enable the QUIC system for fast, tool-free module insertion and extraction, reducing setup time and mechanical stress on connectors.
**Thermal Management**
The Pressurized Air Channel cooling system delivers clean, uniform airflow directed through the right side and exhausted through the left, maintaining optimal operating temperatures across all module slots.
**Power Supply Access**
Rear-panel power input simplifies power supply serviceability and reduces mainframe downtime during maintenance.
## Typical Applications
This backplane module suits cost-effective VXI configurations requiring 6 slots without the footprint of larger mainframes. Ideal for portable and rack-mount test systems, measurement platforms, and signal processing applications in laboratory and production environments.
## Compatibility & Integration
The E1421-66501 functions as an integral component of the E1421B mainframe ecosystem, managing VXIbus device interconnection, power distribution, and thermal control. Its compact C-size form factor and modular design enable flexible instrument configurations while maintaining full compliance with VXIbus standards for cross-vendor module interoperability.
