SSeries Signal GeneratorsAeroflex announced its S-Series RF signal generator family touting simplicity, portability, modularity, and RF performance at an attractive price. The first in the series is the SGA analog RF signal generators. They are compact and lightweight with low phase noise, accuracy and fast settling time. The intuitive LCD touch-screen interface allows modulated or swept RF signals to be set up using fewer keystrokes than required by traditional soft key models, thus saving the engineer’s time and reducing the risk of error. A modular format, featuring the new Aerolock locking mechanism, allows additional RF instruments such as a second signal generator and combiner to be mechanically coupled externally by the user. The Aeroflex SGA is currently available in two models: the SGA 3, which has an operating frequency range of 100 kHz – 3 GHz, and the SGA 6 covering 100 kHz – 6 GHz. The SGA is half rack width and 4U high, and weighs less than 17 lbs (8 kg) – less than half the weight of its predecessor. This makes it simple for one person to move it around the laboratory or to use in the field. A typical single sideband (SSB) phase noise specification of -135 dBc/Hz at 20 kHz offset from a 1 GHz carrier means that the signal generator can easily measure receiver selectivity beyond 80 dB. Fast frequency settling times of 1 ms in conventional frequency selection mode, or 100 µs in list mode, make the SGA particularly suited for frequency hopping and semiconductor test applications, as well as ensuring maximum throughput in a production environment. Maximum RF output power is +13 dBm, with a resolution of 0.01 dB, and a high power option is available to extend the maximum calibrated RF level to +20 dBm. Power level can be switched rapidly using an electronic attenuator, in less than 100 µs to within 0.1 dB of final value, and repeatability is better than 0.05 dB. A digital sweep of carrier frequency, RF level and modulation source is included, with single, continuous or externally triggered modes, as well as a list mode sweep facility.
