6 Set the resolution bandwidth to capture the full
bandwidth of the FM signal. To calculate the
required bandwidth use
RBW =((2 x Frequency Deviation)+(2 x Modulation
Rate))
In our case the RBW should be: (2 x 10 kHz) +
(2 x 1 kHz) = 22 kHz With 1- 3- 10 sequence
RBW selections, choose the next highest RBW of
30 kHz:
Press [BW/SWP] > 30 > {kHz}.
7 Turn on the FM demodulator:
Press [SPAN] > {Demod} > {FM ON}.
Listen to the FM audio signal.
Press [SPAN] > {Demod} > {Speaker Vol}, rotate the
knob.
Alternatively you can also use the headphone
jack.
