8 Frequency Scan Measurement
Meas Setup
For log amplitude interpolation and linear frequency interpolation, the interpolation is computed as:
For log amplitude interpolation and log frequency interpolation, the interpolation is computed as:
Note that 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.

Amplitude Interpolation
Sets the interpolation to linear or logarithmic for the specified limiting points set, allowing you to determine
how limit trace values are computed between points in a limit table. See "Frequency Interpolation" on page
485 for the equations used to calculate limit values between points.
