Mi-Waves’ 511 series precision programmable rotary vane attenuators are available in full waveguide bands from 5.0 to 220.0 GHz. Attenuation control is either manually via a front panel or remote controlled using a standard IEEE- 488 interface. The attenuators’ small compact size incorporates both the electronic controller and microwave components. The unit operates from a single +24 volt DC source or with an optional AC adapter.
Attenuation range is from 0 to 60 dB in 0.1 dB steps with 0.05 dB steps from 0 to 20 dB. A digital readout is provided on the front panel to display attenuation settings. The attenuators are highly reliable and designed to be used in ATE and remote power control applications. RS-232 Control Also Available.
Calibration Accuracy is 0.1 db or 2% of reading whichever is greater to 40 db, 3 % from 40 to 50 db and 50 db and above is for reference level only not calibrated.
Flatness +/- 2 % of indicated value or +/- 0.5 db whichever is greater
