Frequency Interpolation
This setting controls how the correction values per-bucket are calculated. We interpolate between
frequencies in either the logarithmic or linear scale.
This setting is handled and stored individually per correction set.
See “Interpolation” on page 936
Interpolation
For each bucket processed by the application, all of the correction factors at the frequency of interest
(center frequency of each bucket) are summed and added to the amplitude. All trace operations and post
processing treat this post-summation value as the true signal to use.
To effect this correction, the goal, for any particular start and stop frequency, is to build a correction
trace, whose number of points matches the current Sweep Points setting of the instrument, which will be
used to apply corrections on a bucket by bucket basis to the data traces.
For amplitudes that lie between two user specified frequency points, we interpolate to determine the
amplitude value. You may select either linear or logarithmic interpolation between the frequencies.
If we interpolate on a log scale, we assume that the line between the two points is a straight line on the
log scale. For example, let’s say the two points are (2,4) and (20,1). A straight line between them on a log
scale looks like:
