AM/FM Demodulation

The Cell Master built-in demodulator for AM, narrowband FM, wideband FM and single

sideband (selectable USB and LSB) allows a technician to hear an interfering signal for

easy identification. The demodulated signal can be heard using either the built-in speaker,

or through a monaural headset connected to the 1/8-inch jack on the test panel.

Demodulation Procedure

Step 1.

Press the

MEAS/DIST

key followed by the

Measure

and

soft keys and the

AM/FM Demod

soft key.

Step 2.

Press the

AM/FM Demod

soft key and select

FM Wide Band

FM Narrow

Band

SSB Lower

, or

SSB Upper

to match the modulation format of the signal.

Step 3.

Press the

Back

soft key.

Step 4.

For AM or FM signals, press the

Demod Freq

soft key and use the keypad to en-

ter the center frequency of the signal to be demodulated. By default, the demod-

ulation frequency is the center of the frequency span.

For SSB Upper and SSB Lower signals, press the

Demod Freq

soft key. By

default the demodulation frequency is the center of the frequency span. If the de-

modulation frequency needs to be changed, press the

Demod Freq

soft key and

enter the correct demodulation frequency. The

BFO Adjust

soft key allows ad-

justment of the beat frequency oscillator to fine tune the signal through a span of

10000 Hz.
