描述
Advanced baseband signal generation

The PSG equipped with Option 002 integrates an advanced dual-mode internal baseband generator with a state-of-the-art vector signal generator to facilitate complex I/Q modulation at microwave frequencies. The high performance baseband generator combines arbitrary waveform generation (ARB mode) with sophisticated real-time I/Q symbol generation (Real-Time mode) to provide a complete baseband solution.

ARB mode provides the utmost flexibility for pre-calculated I/Q waveform playback within the baseband generator's deep memory limits. Real-Time mode employs a real-time I/Q symbol builder to generate a broad range of digital modulation formats with continuous data streams for BER measurements, without the memory constraints and lengthy waveform calculations commonly associated with traditional arbitrary waveform generation.

Typical applications

The internal baseband generator is recommended for component and receiver test applications requiring digitally modulated test signals at baseband, IF, and microwave frequencies up to 20 GHz. Common applications include proprietary waveform generation, broadband communications signal generation, complex radar test pattern generation, and intermodulation distortion testing.东莞市网仪电子仪器有限公司
