Analysis the Demodulated Signals
75
Press {More 1 of 3} > {More 2 of 3} > {Attenuation
Auto} > {More 3 of 3}
5 Press {Y Scale} > {Auto Scale} > {Return} to set the Y
scale.
6 Set the FM deviation limit and turn on the limit
function:
Press {More 1 of 3} > {Limits} > {FreqDev UP} > [11] >
{%} > {FreqDev Low} > [9.9] > {%} > {Limits on} >
{Return}
The red value in the result indicates the demodulated
fM deviation exceeds the limits set as above.
