Description
The PXI Arbitrary Waveform Generator, part number 777956-01, is a sophisticated instrument designed for a wide range of applications requiring precise signal generation. This specific model, the PXI-5431, falls under the category of PXI Video Signal Generators, offering advanced features tailored for high-quality video signal generation.
At the core of its functionality is the Direct Digital Synthesis (DDS) method for waveform generation. This technology allows for high-frequency precision and resolution, ensuring that the generated signals are of the utmost quality. The DDS method benefits from a 12-bit DAC, which contributes to its ability to produce detailed and accurate waveforms.
The PXI-5431 boasts a range of features designed to enhance its performance in various settings. These include temperature stability, wideband tuning, and fast and phase-continuous frequency switching, making it a versatile tool for many applications. Frequency generation is accomplished using a 32-bit, high-speed accumulator coupled with a lookup memory, enabling the device to handle complex signal generation tasks with ease.
An important aspect of this generator is its SYNC Output, which delivers a TTL form of the sine waveform through a hysteresis buffer and a 50 Ω series resistor. This feature is crucial for synchronizing the generated signal with other instruments or components within a system.
The PXI-5431 also offers a DC Offset Capability of up to ±2.5 V before the attenuation chain, allowing users to adjust the baseline of the waveform as needed for specific applications. However, it’s worth noting that waveform clipping may occur if the waveform maximum plus offset exceeds ±5 V into 50 Ω without the 10-dB attenuator, highlighting the importance of careful setup and configuration to avoid signal distortion.
Overall, the PXI-5431 PXI Arbitrary Waveform Generator is a highly capable and flexible instrument, ideal for professionals seeking precise and reliable signal generation for video and other high-frequency applications.
