be left out of the file altogether.
The Overlap row and the two Bias rows apply only to external mixing. Both are read-only, they are never
written by the analyzer. The only way to insert or modify these rows is to edit the file with a text editor or a
spreadsheet editor. These rows are intended for use by mixer manufacturers, as they allow the
manufacturer to insert data about how the mixer corrections were generated and how they should be
applied. The Bias rows allow you to specify whether to turn Bias on or off when the Correction is turned on
and to specify a Bias value (turning off the Correction does not change the Bias, but turning it back on again
sets it to the value specified in the file). The Overlap row allows you to specify an overlap region in which

May be empty but may not be omitted
May be empty but may not be omitted
assumed to be Hz if omitted
If omitted leaves the Antenna unit
unchanged. The amplitude unit in the
Antenna Unit field is a conversion factor
that is used to adjust the Y Axis Units of
the current mode, if the mode supports
Antenna Units. For more details on
antenna correction data, refer to the
Input/Output,Corrections key description.
Allowable values: dBuv/m, dBuA/m, dBG,
dBpT, None
if omitted leaves the Freq Interpolation
unchanged. Allowable values: Linear,
Logarithmic
If omitted leaves the Bias value
unchanged (added as of A.08.50)
If omitted leaves the Bias State
unchanged. Allowable values: On, Off
(added as of A.08.50)
Uses Freq Unit from line 6. Thus, in this
example Freq1=33.5 GHz, Freq2= 40.0
GHz (see note below). If omitted leaves
the overlap unchanged (added as of
A.08.50)
