2) FM STEREO Standard Signal
In FM broadcasting system, 100% modulation (Maximum system deviation) means 75kHz
deviation. For receiver test 100% and 30% (22.5KHz deviation) is most frequently used. These
values can be entered quickly using
most commonly used FM receiver test standards, IHF and JIS is provided in Table 3.1.

3.3.4.1. Normal Mode
Increment or decrement the current address in steps of 1 or 10 using
☞ ☞ ☞ ☞
When address value is increased or decreased by 1, the address may jump to some other
address. This is not due system problem but due to 'Address Rotation Function' of the
instrument. ( Refer to 3.3.4.3 )
When new address is entered, the instrument setting may change due to the stored data;
this is because the instrument is in 'Sequential Recall Mode '. (Refer to 3.3.5.5)
