The National Instruments PXIe-6739, part number 783801-01, is a high-density analog output device featuring 64 voltage output channels with a resolution of 16 bits, allowing for 65,536 discrete output levels. This module operates across an output voltage range of -10 V to 10 V, with a current drive capability of ±10 mA per channel, making it suitable for a variety of waveform generation and control system applications. The device supports a maximum output update rate of 1 Mega sample per second when deploying one channel, or 350 kilo samples per second with all 64 channels in simultaneous operation. The PXIe-6739 ensures timing accuracy of 50 parts per million (ppm) and a resolution of 10 nanoseconds, alongside a differential nonlinearity specification of ±1 LSB at maximum settings and a settling time of 15 microseconds for a full-scale step. Additionally, it features low output impedance of 0.2 Ω, which supports high driving current and output stability under passive load conditions. The onboard First In First Out (FIFO) module, which can store up to 65,535 samples, enables the generation of both periodic and non-periodic waveforms with minimal latency. The device is equipped with 20 programmable digital I/O channels, which can generate and accept waveforms using FIFOs of sizes 2,047 samples and 255 samples for output and input, respectively. Programmable filters with time periods of 160 nanoseconds, 10.24 microseconds, and 5.12 milliseconds are also provided for enhanced flexibility. With an operational temperature tolerance of up to 55 degrees Celsius and a humidity rating below 85%, the PXIe-6739 is designed to perform reliably in diverse environments. The module measures 16 cm x 10 cm (6.3 in. x 3.9 in.) and weighs 173 g (6.1 oz), making it a compact addition to any instrumentation setup.
