The National Instruments part number 783800-01 refers to the PXIe-6738 PXI Analog Output Module, an advanced solution for high-performance signal generation suitable for diverse applications including data acquisition, control, and simulation. This module features 32 voltage output channels, each equipped with a 16-bit resolution digital-to-analog converter (DAC), ensuring exceptional signal fidelity. It is capable of achieving a maximum update rate of 1 MS/s for single-channel output, 1 MS/s for up to eight channels, and 350 kS/s when all 32 channels are in use. The module supports a FIFO buffer capacity of 65,535 samples, allowing for seamless and efficient signal production.

Programmable voltage ranges of ±10 V and an external reference input range of ±11 V enhance its versatility, while an output impedance of 0.2 Ω and current drive capability of ±10 mA provide compatibility with various load types. The PXIe-6738 is designed with reliability in mind, featuring short-circuit protection to ground and a dynamic performance characterized by a slew rate of 3.0 V/µs and a noise level of 1.0 mV RMS up to 1 MHz. Settling time reaches 15 µs to ±4 LSB accuracy, ensuring rapid and precise signal updates.

This module operates effectively in ambient temperatures ranging from 0 to 55 degrees Celsius and relative humidity levels of 10% to 90%, noncondensing. The rugged construction of the 783800-01 allows it to withstand operational shocks of 30 g peak and operational vibrations from 5 to 500 Hz at 0.3 g RMS, as well as non-operational vibrations of 5 to 500 Hz at 2.4 g RMS. Designed for indoor use, it can be mounted at altitudes up to 2000 meters and has a pollution degree rating of 2. The module weighs 164 g (5.8 oz), making it a compact and reliable choice for demanding test and measurement environments.
