Variable attenuators

Series DB-2900 variable attenuators suit bit-error-rate testing, optical-loss margins measurement, optical power-meter and test-set calibration, system-loss simulation and optical-component testing. DB-2900C is used in cable-TV, high-speed telecommunications and high-speed analog systems. DB-2910 provides testing for LAN and standard telephony applications, and DB-2930 is used in multimode applications. All models provide continuous attenuation with or without battery power.
