Rohde & Schwarz has enhanced its fully integrated SGS100A by adding a model for I/Q modulated signals from 80 MHz to 12.75 GHz. Combined with an I/Q baseband generator, the instrument can be used to generate test signals for all radio standards in this frequency range. This renders the new vector signal generator suitable for X-band signals from 8 GHz to 12 GHz in radar and satellite communications. The I/Q modulator's RF bandwidth of 1 GHz makes it possible to generate pulses with high chirp bandwidths and steep pulse edges. Designed for use in automatic test systems, all models can switch between the wanted frequency and level settings in typ. 280 µs. They offer an output level of typ. +22 dBm and have an electronic step attenuator covering the entire frequency range. The generator boasts high reference frequencies of 100 MHz and 1 GHz, which ensures excellent phase stability for phase-coupled applications involving multiple signal generators. This new model of the SGS100A vector signal generator for I/Q-modulated signals from 80 MHz to 12.75 GHz is available now.
