Rohde & Schwarz SMA100A Signal Generators

The SMA100A combines superior signal quality with very high setting speed, which makes it ideal for any task. Whether in development, production, service or maintenance, the SMA100A does an excellent job.

In the frequency range from 9 kHz to 6 GHz, it can generate CW signals as well as all common types of analog 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.

• USB, GPIB, LAN

Excellent signal quality

The SMA100A is the ideal solution for measurement applications requiring high spectral purity, e.g. adjacent-channel or phase-noise measurements, and is also optimal for use as a local oscillator or VCO.

Due to an innovative synthesizer concept, the standard version of the instrument already offers excellent values in terms of broadband noise, SSB phase noise and nonharmonics suppression. The Enhanced Phase Noise Performance and FM/jM Modulator option (SMA-B22) even further improves SSB phase noise for frequency offsets of up to approx. 100 kHz as well as nonharmonics suppression. The SMA100A is, therefore, the ideal signal source for measurement tasks that place exacting requirements on spectral purity (e.g. A/D and D/A converter tests).

Ideal for use in production

The R&S SMA100A features the very short level and frequency setting times that Rohde & Schwarz signal generators are known for and is thus an ideal choice in time-critical measurement systems. Setting times are already shorter than 3 ms in normal operation. A further significant reduction (<450 µs) is achieved in the list mode, which uses frequency and level settings previously stored in a list.
