Advanced Baseband Signal Generation

Option 001 integrates an advanced dual-mode internal baseband generator with a state-of-the-art vector signal generator to facilitate complex I/Q modulation at RF 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 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 RF frequencies up to 6 GHz. Common applications include proprietary waveform generation, single and multicarrier cellular communications signal generation, WLAN and Bluetooth signal generation, and intermodulation distortion testing.

This option cannot be added as a product upgrade only available at time of purchase.
