Lines 2 through 5 can be empty but must appear in the file. Lines 6 through 11 are optional, the lines can

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 test set. 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 two different corrections may be applied. It is expected that in the corrections data itself, there

will be TWO corrections values exactly at Max Freq, otherwise Overlap is ignored. The way the overlap

is processed is as follows: if at any given time the current test set Start Freq is greater than Freq 1 and

lower than Freq 2, and the current Stop Freq is greater than Freq 2, extend the first correction point at or

above Freq 2 down to Freq 1, rather than using the correction data between Freq1 and Freq2.

The Antenna Unit row can only be used in Correction register 1, because there can only be one setting

for Antenna Unit at any given time. If a Correction whose Antenna Unit is set to anything but None is

loaded into any Correction register but 1, an error is generated (Mass storage error; Can only load an

Antenna Unit into Correction 1). When a correction file is saved from any Correction register but 1,

Antenna Unit is always written as None.

Similarly, the Bias rows can only be used in Correction register 1, because there can only be one setting

for Bias at any given time. If a Correction file with a Biasor Bias State row is loaded into any Correction

The data follows the DATA row, as comma separated X, Y pairs; one pair per line.

For example, suppose you have an Antenna to correct for on an N9020A version A.02.06 and the

correction data is:

• 0 dB at 200 MHz

• 17 dB at 210 MHz

• 14.8 dB at 225 MHz

Then the file will look like:

• Amplitude Correction

• "Correction Factors for 11966E"

• "Class B Radiated"

• A.02.06,N9020A

• P13 EA3 UK6,01

• Frequency Unit,MHz

• Antenna Unit,dBuV/m

• Frequency Interpolation,Linear
