RF signal generator gets in touch


Electronica, Munich –  The S-Series RF signal generator family from Aeroflex is based on an innovative touch screen design which removes the need for buttons, rotary controls, and deeply nested software menus.

The first in the series is the Aeroflex SGA analog RF signal generator that provides a reliable and repeatable signal source solution for general-purpose, aerospace and military test applications in laboratory, factory and field environments.

The S-Series is planned to expand with the inclusion of digital signal generators for wireless-specific measurements including LTE, LTE-A and IEEE 802.11ac standards, and a range of signal analyzers.

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, saving the engineer’s time and reducing the risk of error.

Aeroflex has also designed the Aerolock locking mechanism which allows multiple 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,
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.

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 measure receiver selectivity beyond 80 dB.

The 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.

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