Vector signal generator supports 12,75 GHz

23 January 2013 Test & Measurement

Rohde & Schwarz has enhanced its SGS100A vector signal generator 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, it 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. Designed for use in automatic test systems, the compact system (one unit high and half of 19” in width) delivers excellent performance across the entire frequency range up to 12,75 GHz.

All models can switch between the wanted frequency and level settings in only 280 μs. They offer a high output level of +22 dBm as standard 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.
