Linear or Logarithmic (Log/dB) interpolation can be selected using the following
menus:
H
AMPLITUDE
→
Corrections...
→
Interpolation...
→
Freq Interpolation
Lin. Linear interpolation of correction values is performed on the frequency
axis using a linear scale.
Log. Linear interpolation of correction values is performed on the frequency
axis using a logarithmic scale.

Ampl Interpolation
Lin.
Linear interpolation of correction values is performed on the amplitude
axis using a linear scale.
dB. Linear interpolation of correction values is performed on the amplitude
axis using a logarithmic scale.
Rules for Creating an Amplitude Correction File.
H
Create the file as a text file and save it with the extension “.cor”.
H
The maximum number of input lines is 3000.
H
The order of correction data input is unimportant because the file is sorted
when it loads. However, it may be easier to follow if you enter data in the
order of ascending frequency.
H
Numeric values are described without the unit of frequency or amplitude
(Hz, dB, W, etc.). For example, 5 MHz frequency is expressed as 5M.
H
Frequency can be expressed as a floating point number or with the SI unit (k,
M, or G). For example, the following lines show three different ways to
express the same value:
1000, 1E+3, 1k
1230000, 1.23E+6, 1.23M
1000000000, 1.0E+9, 1.0G
H
Amplitude is expressed as a decimal number or integer (such as 1.23 or 10).
H
Do not use a space in a numeric value; however, you can space before and
after “=”.
Correct: 10M = 10 (A space is inserted before and after “=”.)
Incorrect: 10 M=10 (A space is inserted between “10” and “M”.)
