Description
High-Performance PXI Waveform Generator
The Tabor 5251 PXI Waveform Generator is a powerful single-channel PXI module that combines frequency agility, high-resolution waveform generation, and advanced modulation capabilities. With a 250MS/s sample rate, it produces sine waves up to 100MHz and square waves up to 62.5MHz. Its 16-bit DAC ensures superior waveform fidelity, enabling precise testing of communication, audio, and video systems.
Advanced Modulation and Frequency Agility
The 5251 supports a wide range of modulation types, including AM, FM, FSK, PSK, ASK, as well as frequency and amplitude hopping and sweep. Its frequency agility allows seamless simulation of frequency-hopping systems or other complex signal scenarios, making it ideal for modern telecommunication testing. Multiple run modes, including trigger, timer, and trigger delay, provide flexible waveform control for diverse testing requirements.
Sequencing and Memory Management
Equipped with 2M waveform memory, the 5251 enables long waveform storage for extended tests. Memory segmentation and sequencing allow the creation of complex, repeatable waveform patterns. Users can store up to 10 different sequence tables, each capable of linking thousands of waveform segments and looping up to 1 million times. This capability enhances test efficiency while minimizing memory usage.
ArbConnection Software and Ease of Use
ArbConnection software simplifies waveform creation, editing, and import from MATLAB, ASCII, or custom sources. Users can design arbitrary waveforms, apply modulation, or use the FM composer for frequency-modulated signals. Ultra-fast DMA downloads and intuitive PXI interface make setup and operation highly efficient.
Compact, Scalable, and Synchronizable
Occupying a single PXI slot, the 5251 saves valuable chassis space while supporting multi-instrument synchronization for phase-controlled multi-channel testing. Its built-in calibration and 1ppm clock stability ensure reliable, high-precision output over time. Ideal for research labs, communication development, and PXI test systems, the 5251 is a future-ready, cost-effective waveform solution.
