FSK Demodulation Analysis
Please refer to the procedures below to analysis the ASK
demodulation.
1 Connect the signal generator to RF IN connector and
turn on the signal generator’s FSK and RF output.
2 Turn on the ASK demodulation analysis function.
Press [MODE], Rotating the knob to highlight Demod-
ulation Analysis
, [ENTER], {FSK}.
3 Press {Carries Freq} > [100] > {MHz} to set the carrier
frequency.
4 Press {Symbol Rate} > [10] > {ksps} to set the symbol
rate.
5 Press {Filter Setup} > {Ref Filter} > {Nyquist} >
{Return} to set the filter type.
6 Set the attenuation state to Auto (default):
Press {More} > {More} > {Attenuation Auto} > {More}
7 Press {Y Scale} > {Auto Scale} > {Return} to set the Y
scale.
8 Setting the FSK deviation limit and turn on the limit
function:
Press {More 1 of 3} > {Limits} > {FreqDev UP} > [41] >
{kHz} > {FreqDev Low} > [39] > {kHz} > {Limits on}
