The National Instruments part number 778396-01 is a multifunction I/O module designed for high-performance data acquisition applications. A part of the PXI-6120 model line, this versatile device features 16-bit analog-to-digital converters (ADCs) for each of its four analog input channels, supporting a maximum sampling rate of 800 kS/s per channel. Tailored for rigorous testing environments such as automotive, sonar, radar, and ultrasound applications, it also includes 16-bit digital-to-analog converters (DACs) for precise output control. In addition to its analog capabilities, the 778396-01 provides two 24-bit counter/timers and eight 24-bit digital I/O lines compatible with TTL, accommodating a broad spectrum of measurement and control requirements. The module operates seamlessly within PCI or PXI bus systems and eliminates the need for physical switching or jumpers, utilizing software calibration and configuration instead. The integrated NI MITE bus interface chip enhances its adaptability while the module's Data Acquisition System Timing Controller (DAQ-STC) delivers maximum timing resolution of 50 ns, supporting applications like buffered pulse generation and equivalent time sampling. A standout feature of the 778396-01 is its Real-Time System Integration (RTSI) bus, facilitating synchronization of multiple measurement devices to a single timing event through a built-in ribbon connection, which alleviates the need for additional cabling within the PXI chassis. Furthermore, the built-in phase-locked loop (PLL) circuit allows synchronization of multiple 778396-01 modules or other compatible PXI devices to a common reference clock. The integrated NI-DAQmx driver and configuration tool streamline the setup and operation of this module, ensuring accurate and reliable data acquisition.

Part number 778396-01 specifications include four pseudodifferential analog input channels, 16-bit ADC resolution, an 800 kS/s maximum sampling rate, eight TTL-compatible digital I/O lines, and two 24-bit counters/timers. Its power requirements are +5 VDC (±5%) at 3.0 A, +3.3 V at 0.8 A, and +4.65 VDC to +5.25 VDC at 1 A at the I/O connector.
