NI DAQCard-AI-16E-4 Data Acquisition Card

The NI DAQCard-AI-16E-4 is a PCMCIA Type II data acquisition card engineered for laptop-based measurement systems. It delivers 16 analog input channels with selectable single-ended, pseudo-differential, or differential configurations, supported by a 12-bit ADC and sampling rates up to 500 kS/s on single channels or 250 kS/s across multiple channels. The card integrates analog and digital triggering, dual 24-bit counters/timers with frequency scaling, and programmable input ranges from ±0.05 V to ±10 V, making it suitable for portable test, monitoring, and data logging applications.
