The National Instruments 778768-01 is a PXI Vector Signal Generator, specifically identified as the PXI-5670, designed to cater to the diverse requirements of product development across various industries, including scientific research, consumer electronics, communications, aerospace and defense, semiconductor testing, software-defined radio, RFID, and wireless sensor networks. This compact 3-slot 3U module generates vector signals within a frequency range of 250 kHz to 2.7 GHz, offering signal levels from -145 dBm to +13 dBm. Its adherence to PXI bus standards ensures easy integration into existing systems, making it a versatile solution for automation applications.

The 778768-01 is equipped with an ultra-high stability oven-controlled crystal oscillator (OCXO), providing an exceptional frequency stability of ±20 parts per billion (ppb) and a frequency accuracy of ±50 ppb. Included with the generator are the Modulation Toolkit for LabVIEW and the NI-RFSG instrument driver, supporting compatibility with NI LabVIEW 7 Express, LabWindows/CVI, and C. This software suite facilitates straightforward definition of time, synchronization, continuous wave (CW) tone, and arbitrary waveform synthesis, alongside features for signal creation, analysis, and visualization using both unique and common analog and digital modulation techniques. Additionally, it supports impairment injection such as IQ Gain Imbalance, Quadrature Skew, and Additive White Gaussian Noise (AWGN), while standard measurement capabilities include Error Vector Magnitude (EVM), Modulation Error Ratio (MER), and correlation coefficient (ρ). The visualization features encompass trellis, constellation, and 2D/3D eye diagrams, enhancing the evaluation of complex signals.

The 778768-01 also boasts extended playback times for intricate modulated signals, with up to 256 MB of deep memory facilitating the synthesis and generation of longer and more sophisticated waveforms, extending up to 1.28 seconds. A comprehensive calibration process ensures power level accuracy across a temperature range of 0 to 55°C, essential for reliable performance in production environments. This functionality positions the 778768-01 as a robust solution for various signal generation needs in the field of industrial automation and control systems.
