Signal quality, speed and flexibility – these are the criteria by which signal generators are measured today. The R&S SMA100A perfectly meets these criteria, and thus is a premium-class analog generator that sets standards due to its outstanding characteristics.
It combines superior signal quality with very high setting speed. Whether in development, production, service or maintenance, the SMA100A does an excellent job.In the frequency range from 9 kHz to 6 GHz, SMA100A can generate CW signals as well as all common types of analog modulation (AM, FM, fM, pulse modulation). Excellent specifications and a wide range of modulation signals – these are the characteristic features of the SMA100A.In addition, a low-jitter clock synthesizer option supplies differential clock signals of up to 1.5 GHz independently of the RF frequency.
This makes the SMA100A suitable for a variety of applications – from use in phase noise test systems through to tests on mixed-signal ICs.The SMA100A signal generator also offers a modern graphical user interface for fast and intuitive operation. The NRP-Zxx power sensors can be connected to the SMA100A. The user can therefore perform very precise power measurements directly with the signal generator.
