The fast, low noise Aeroflex SGA is a compact, easy to use, high performance signal generator for R&D, manufacturing, and the field.

The 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.

A typical single sideband (SSB) phase noise specification of -135 dBc/Hz at 20 kHz offset from a 1 GHz carrier means that the SGA 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.

The SGA employs a large touch-screen user-interface to provide a signal generator with unparalleled ease of use. With such a small form-factor, the SGA is equally at home in the field as it is in the laboratory or a production line. The use of the Aeroflex Fast Low Noise Synthesis (FLNS) technology, added to the experience gained through decades of developing leading-edge signal source products, ensures that signal purity and integrity have not been sacrificed in the quest for speed; the SGA excels in all respects.

Options are available for AM/FM/phase modulation, adding four internal 10 MHz oscillators and two external modulation inputs, and for pulse modulation.

With a comprehensive range of features and options, the SGA meets the needs for a general-purpose signal generator while offering the high performance required of demanding, critical receiver measurements or rapid manufacturing.
