Freq Interp Log Lin allows you to determine how limit
trace values are computed between points in a limit
table. The available interpolation modes are linear and
logarithmic. If the linear mode is used for both
frequency and amplitude, a straight line is used when
interpolating between points in a limit table. If
frequency interpolation is logarithmic, frequency
values between limit points are computed by first
taking the logarithm of both the table values and the
intermediate value. A linear interpolation is then
performed in this logarithmic frequency space. An
exactly analogous manipulation is done for logarithmic
amplitude interpolation. Key Access:

NOTE Interpolation modes determine how limit values are computed between
points in the limit table. The appearance of a limit trace is also affected
by the amplitude scale, which may be linear or logarithmic.
