Direct Reading Precision Electronic Attenuators (Series 515)
Mi-Wave’s 515 Series Direct-reading electronic Precision Attenuators provide 0 to 60 dB of calibrated attenuation by rotation of a resistive vane mounted in a circular waveguide section. These units are often referred to as precision rotary vane attenuators.
