The AFQ100A is a state-of-the-art, self-contained and flexible baseband source that perfectly meets those requirements. Besides, there is a growing need for development and testing in the digital baseband domain. The signals to be created are increasingly complex and dynamic. They use complex modulation schemes and demand more and more bandwidth.
An important component of such test equipment is a flexible baseband source that allows development and production tests to be performed on state-of-the-art receivers for a variety of standards. A self-contained baseband source must fulfill a wide range of signal requirements. Plus, it needs variable digital and analog outputs in order to directly operate the DUT. Used as a modulation source for vector signal generators, the R&S®AFQ100A provides I/Q signals that offer all the sophistication of modern communications standards for generating the required RF signal.
Featuring a maximum clock rate of 300 MHz and a waveform memory of up to 1 Gsample, the R&S®AFQ100A generator provides unprecedented functionality and offers precisely the flexibility that is required. It allows long sequences to be generated for bit error ratio measurements; moreover, its high clock rate provides the necessary bandwidth for supporting future broadband communications systems.
