– Key Features

Onboard software-based self-calibration eliminates potentiometer adjustment. The board requires 15 minutes warm-up time and annual calibration intervals. Dual-mode analog triggering allows direct input or post-gain signal routing for flexible measurement control.

– Typical Applications

Data logging, process control, and automated test systems benefit from this card’s multi-range input capability—particularly when acquiring low-level signals below 50 mV alongside standard-range measurements.

– Compatibility & Integration

PCI bus interface with software support for LabWindows/CVI and Measurement Studio for Visual Basic and Visual Studio .NET. NI-DAQmx driver support available; terminal naming may differ in NI-DAQmx versus Traditional NI-DAQ (Legacy) implementations.
