The National Instruments part number 778697-01 identifies the PXI-5421 PXI Waveform Generator, a high-performance module designed for the PXI Express (PXIe) platform. This waveform generator is optimized for applications demanding high bandwidth and low latency, making it an excellent choice for precise timing and synchronization tasks. It features a single analog output channel with a SMB jack connector and a direct output path, delivering a resolution of 16 bits via a digital-to-analog converter (DAC). The device provides a 43 MHz analog baseband bandwidth measured at -3 dB and incorporates a finite impulse response (FIR) digital interpolation filter, supporting interpolation factors of 2, 4, or 8.

In terms of power consumption, the PXI-5421 typically operates at 21.9 W, with a maximum power draw of 26.0 W during overload conditions. The module requires 1.9 A at +3.3 VDC, 2.0 A at +5 VDC, 0.46 A at +12 VDC, and 0.01 A at -12 VDC under normal operation. Compatibility with various software environments, including LabVIEW, LabWindows™/CVI™, Measurement Studio, and Microsoft Visual development tools, enhances its integration flexibility.

The waveform generator is equipped with advanced triggering features, allowing for precise control of test execution through start triggers, script triggers, and software triggers. Its maximum input and output overloads are both in the range of -2 to +7 V, with a 1 kΩ input impedance and a 50 Ω output impedance, ensuring robust signal handling. Operating conditions for the PXI-5421 are designed for indoor use, with capabilities to function at altitudes up to 2000 meters and in ambient temperatures ranging from 0 to 55 degrees Celsius. The device can withstand humidity levels from 10% to 90% non-condensing, along with storage conditions from -25 to 85 degrees Celsius and a storage humidity range of 5% to 95% non-condensing. The module is built to endure operating shocks of 30 g and vibrations of 5 to 500 Hz, complying with IEC 60068-2-27 and IEC 60068-2-64 standards, respectively.
