National Instruments 777795-01

The National Instruments part number 777795-01, known as the PXI-6713 Analog Output Module, is a high-performance device designed for precision signal processing in industrial automation and control systems. This module features eight voltage output channels, each equipped with a 12-bit resolution digital-to-analog converter (DAC) that enables efficient conversion of digital signals to analog form. With a maximum update rate of 1 Mega samples per second per channel, the PXI-6713 ensures rapid and accurate waveform generation, whether using host PC memory or the integrated First In First Out (FIFO) module. This FIFO supports a buffer size of 16,384 samples, allowing for high-resolution signal processing capabilities.

The PXI-6713 provides programmable output voltage ranges of ±10 Volts, with an additional external reference input range of ±11 Volts. Features such as a low output impedance of 0.1 Ω and capability to drive loads up to ±5 mA make it suitable for a variety of applications. Built-in short-circuit protection further safeguards the internal circuitry from damage. Additionally, the module includes eight TTL/CMOS-compatible digital I/O lines for static input and output operations, as well as two 24-bit counter/timers and a 4-bit frequency scaler, facilitating clock signal generation and precise time measurements. The counter/timers support base clock frequencies of 20 MHz and 100 kHz.

For enhanced performance, the PXI-6713 has a slew rate of 20 V/µs, a noise level of 200 µVrms, and guarantees a settling time of 3 µs to ±0.5 Least Significant Bit accuracy, ensuring quick and precise signal updates. The module also features low total harmonic distortion of -80 dB when generating a 10 Volt, 1,000-point, 750 Hz sine wave, maintaining outstanding signal integrity. Compact in design, the PXI-6713 measures 16 cm x 10 cm (6.3 in. x 3.9 in.) and weighs approximately 126 grams, making it an ideal choice for portable applications in various industrial settings.
