Profile: Opticus provides a wide range of optical fibre and telecommunication test product solutions. Our products include attenuators, cable, antenna & spectrum analyzers, monitoring systems, optical fault locators, optical meters, optical sources, optical visual fault locators and signal generators. The OVA-2 optical attenuator is a simple to operate continuous variable attenuator in a handheld format and is ideal for installation & maintenance, research & production. The MG3690C series of broadband signal generators covers audio, HF, VHF, UHF, RF and microwave frequencies from 0.1 Hz to 70 GHz in single coaxial output and up to 325 GHz or beyond, with external multipliers. Thus, the MG3690C series is an ideal signal source for both RF and microwave requirements, fully configurable for simple to high performance applications. The MG3690C replaces the existing MG3690B signal generator, offering three levels of SSB phase noise performance, standard, ultra low phase noise (option 3) and premium phase noise (option3X, along with full suite of modulation capabilities for signal simulations from simple to the most complex. For IQ modulation, the IF input option allows the easy up-conversion of an externally IQ-modulated RF signal.
