Rohde & Schwarz has enhanced its fully integrated R&S 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. As a result, the R&S SGS100A is ideal for X-band signals from 8 GHz to 12 GHz for radar and satellite communications. The I/Q modulator's wide RF bandwidth of 1 GHz makes it possible to generate pulses with high chirp bandwidths and steep pulse edges.
