The NI 184639-01 E Series Calibration Fixture is a specialized adapter that connects high-precision calibration equipment to National Instruments E Series DAQ devices. It eliminates repetitive cable disconnections during multi-step calibration procedures, reducing signal degradation and connection errors. The fixture provides a stable, shielded environment for accurate calibration workflows while supporting direct integration with NI Calibration Executive software and IVI-compatible instruments.
Technical Specifications
Connector Configuration
• One (1) BNC connector for frequency counter connections
• Three (3) connectors for HI/LO/Guard calibrator connections
• Two (2) connectors for HI/LO DMM connections
• Primary interface: 68-pin SCSI II connector for E Series devices
• Alternative support: 100-pin connector for E/S Series devices
Signal Integrity & Shielding
Enhanced shielding preserves signal integrity throughout calibration sequences. Compatible with shielded DAQ cables (NI Sh68-68-EP) and low thermal copper EMF plug-in cables for high-accuracy measurements.
Environmental Operating Conditions
• Temperature range: 18 °C to 28 °C during calibration
• Maximum relative humidity: 80%
• Temperature drift specification (E Series): ±10 °C from last external calibration temperature
• Recommended warm-up time: 15–30 minutes for thermal stabilization
– Key Features
• Simplifies calibration workflows by consolidating connection points
• Extensible design supports SCB-68 and BNC-2110 terminal blocks for custom configurations
• Compatible with both standard and extended I/O DAQ architectures
• Reduces connection errors inherent in frequent cable reconfiguration
– Typical Applications
Precision calibration of E Series and S Series DAQ devices in laboratory and production environments requiring automated or manual calibration workflows with external instrumentation.
– Compatibility & Integration
Designed for NI E Series DAQ devices with 68-pin SCSI II connectors. Supports E/S Series devices with 100-pin connectors when a 68-pin MIO-16 cable is connected. Integrates with National Instruments Calibration Executive software and IVI-supported calibration instruments for automated workflows.
