Major Tone Frequency; Minor Tone Frequencies (Esa-Like And Usb Tone Standards) - Safran CORTEX CRT Quantum User Manual

major and minor tone frequencies are fully programmable:

3.6.2.1. Major Tone Frequency

The major tone frequency is programmed according to the following rule (in kHz):
with the following restrictions:

5 ≤ ��
����������_��������

1 ≤ ��
����������_��������

��
����������_��������

depending on factory settings (refer to Annex 5), ��
ESA code standards).

3.6.2.2. Minor Tone Frequencies (ESA-like and USB Tone Standards)

The minor tone frequencies are programmed according to the following rule (in kHz):
with the following restrictions:

1 ≤ ��
����������

1 ≤ ��
����������

��
����������_��������

In ESA-like and USB standards, the ratio between Q factors of two minor tones can be a non-integer
value (see note below) but the Q factor for any minor tone must be a multiple of ��

��
����������_��������

��
����������_��������
USING NON-INTEGER RATIOS BETWEEN MINOR TONE « Q » FACTORS ALLOWS TO INCREASE THE AMBIGUITY
DISTANCE MUCH BEYOND THE WAVELENGTH OF THE LOWEST VIRTUAL MINOR TONE.
IN THIS CASE, THE « FIXED SEQUENCE » OR « NO FIXED » OPERATING MODE MUST BE SELECTED
TO AVOID FALSE AMBIGUITY SOLVING (SEE SECTION 3.6.4.7, SCENARIOS 2 & 4).
