Single and multicarrier custom modulation
Option 431 enables generation of custom digital modulated signals using the internal arbitrary waveform generator. Create signals with pre-defined modulation types such as BPSK and 1024QAM or use quick set-ups for standards like Bluetooth and GSM.
Advanced baseband signal generation
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 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 application
Digitally modulated signals can be used for receiver characterization and design, such as modulation accuracy (error vector magnitude).
This option can be added as a product upgrade.
