FCT (F1) function.
4.2.5.2

The F2 function

This function enables the user to vary the frequency of the sound subcarrier
from 4 to 9 MHz, in 62.5 kHz steps.
This function is necessary if the user wants to vary the frequency of the sound
subcarrier related to the measurement of the V/A ratio (see Point 4.2.6). The instrument
takes as the default frequency the value configured in the factory (or a customized
configuration through RM-004). However, with the F2 function the user can vary the
sound subcarrier value manually, from 4 to 9 MHz.
Example 11. Changing the sound subcarrier frequency from the standard value to 5.74
(Zweiton Stereo).
