Frequency Interpolation
This key is grayed out if Time is the selected X Axis Units. Sets the interpolation between
frequency points, allowing you to determine how limit trace values are computed between points
in a limit table. The available interpolation modes are linear and logarithmic. If frequency
interpolation is logarithmic (Log), 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.
Note that the native representation of amplitude is in dB.
For linear amplitude interpolation and linear frequency interpolation, the interpolation is
computed as:
For linear amplitude interpolation and log frequency interpolation, the interpolation is computed
as:
For log amplitude interpolation and linear frequency interpolation, the interpolation is computed
as:
