The Model 2920A Vector Signal Generator outputs both CW and modulated signals from 10MHz to 4GHz or 6GHz for R&D and production testing of wireless chipsets, wireless modules, and wireless devices. This no-compromise signal generator combines high speed with outstanding phase noise performance. Competitive signal generators only permit optimizing for either speed or low phase noise. Instead, the Model 2920A allows optimization for either aspect of performance at any time and also allows you to get excellent speed even when you are optimizing for phase noise performance. The Model 2920A can download waveform files at high speed and offers an arbitrary waveform generator capable of bandwidths as wide as 80MHz, so it can download large, complex, wide-bandwidth signal files quickly. That helps researchers develop sophisticated new wireless transmission schemes and production test engineers develop test schemes that exercise their devices thoroughly. |
