Making Complex Measurements

Demodulating and Listening to an AM Signal

11.Press Det/Demod, Detector, Sample to set the detector mode of the analyzer to Sample.

12.Press Det/Demod, Demod, AM. Use the front panel volume knob to control the speaker volume.

13.You can turn your analyzer into a % AM indicator as follows:

a.Set trigger to free run by pressing Trig, Free Run.

b.Set the sweep time to 5 seconds by pressing Sweep,

Sweep Time, 5, s.

c.Set the video filter to 30 Hz by pressing BW/Avg, Video BW, 30, Hz.

d.Change the reference level to position the trace at midscreen by pressing AMPLITUDE, Ref Level, and adjust the reference level using the front-panel knob.

e.Reset the video filter to a high value. For example, press BW/Avg,

Video BW, 30, kHz.

f.Set the sweep time to 5 milliseconds by pressing Sweep, Sweep Time, 5, ms.

The center horizontal line of the graticule now represents 0% AM; the top and bottom lines, 100% AM. See Figure 2-17.

14.The signal to the speaker will be interrupted during retrace because the analyzer is performing automatic alignment routines. To eliminate the interruption and clicks between sweeps, turn the auto alignment function off by pressing System, Alignments, Auto Align, Off.

NOTE

Refer to the specifications for information about operating the analyzer

 

with the alignments turned off.
