While Mobile phones are allowed to require approximately 3 time slots for switching from transmission to reception, base stations must be able to transmit and receive at a new frequency in every time slot in the frequency hopping mode. This behaviour must of course be tested and measurements carried out on the base station transmitter and receiver. Since there is no signal generator which is able to settle at different frequencies from one to the next time slot with GSM modulation, a solution to this problem was found by linking two Signal Generators SME in such a way that they alternately provide signals at different frequencies.

With advances in digital signal processing techniques modern wireless communications systems and radar systems have become increasingly digital and more constraints have been placed on packing more information into less and less bandwidth. On the wireless side, modulation formats have become more complicated with less margin for symbol error. On the radar side, modern radar systems are trying to extract more information about the targets they track and provide the ability to track slow moving targets such as automobiles and personnel in the presence of clutter.For both communications and radar systems one of the key RF parameters that limits system performance is phase noise. As systems engineers develop new and more advanced RF systems, phase noise of oscillators and transmitters can no longer be overlooked.This application note will focus on phase noise measurements for pulsed RF carriers such as those used for radar systems. We will address some of the physical limitations relating to pulsed phase noise measurement and introduce the capabilities of the new Rohde & Schwarz FSWP phase noise analyzer.
