Table of Attenuation Error as a Function of Vane-angle Error for Rotary Vane Attenuators

The table of attenuation error as a function of vane-angle error gives the error in decibels caused by vane misalinement [sic.] which is common in the rotary vane attenuator.The attenuation errors corresponding to vane-angle errors ranging from zero to 0.499 degrees (in increments of 0.001 degrees) are presented for selected angles over the range of attenuation values from 0.01 to 70 db.The table is divided into the following intervals of attenuation value increments:0.01 - 0.1 db in 0.01-db increments, 0.1 - 1.0 db in 0.1-db increments, 1 - 20 db in 1-db increments, and 20 - 70 db in 5-db increments.(Author).
