Spectrum Analyzer MG

2-19 AM/FM/SSB Demodulation

The built-in demodulator for AM, narrowband FM, wideband FM, and single sideband
(selectable upper sideband (USB) and lower sideband (LSB) signals) allows a technician to
hear an interfering signal. The demodulated signal can be heard using either the built-in
speaker or a monaural headset connected to the 2.5 mm jack on the connector panel.

Procedure

1.

Press the

Shift

key followed by the

Measure

(

4

) key. Then press the

AM/FM Demod

submenu key.

2.

Press the

Demod Type

submenu key and press

FM Wide Band

,

FM Narrow Band

,

AM

,

USB

, or

LSB

to match the modulation format of the signal.

3.

Press the

Back

submenu key.

4.

Press the

Demod Freq

submenu key and use the keypad or rotary knob to enter the

center frequency of the signal to be demodulated. For USB and LSB signals, fine tune
the signal by adjusting the

Beat Freq Osc

. By default the BFO frequency is set to zero,

meaning that the re-injected carrier is exactly at the demodulation frequency. The

Beat Freq Osc

submenu key allows adjustment of the beat frequency oscillator to fine

tune the signal through a span of ± 10000 Hz.

5.

Press the

On/Off

submenu key to enable the demodulation.

6.

Press the

Volume

submenu key and use the up or down arrow keys or the rotary knob to

change the audio volume from 0% to 100%. For most headsets, a volume of 40% is
adequate.

7.

The

Demod Time

submenu key sets the time that the instrument will demodulate the

signal. Enter a value from 100 ms to 500 seconds.
