The table of attenuation error as a function of vane-angle error gives the error in decibels caused by vane misalinement 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).

The table of attenuation as a function of vane angle gives the attenuation in decibels produced by an angular displacement of the vane of a rotary-vane attenuator assuming ideal behavior of the attenuator.The attenuations for vane angles corresponding to the function A = -40 log10 cos theta are given in the table, where A is the attenuation in decibels and theta is the vane angle in degrees.The attenuations in deci * bels are given for increments of 0.001 deg for the values of theta from zero to 89.999 deg to the sixth decimal place and for the values of theta from 89.000 degto 89.999 deg to the fifth decimal place.(Author).
