Analog Measurements

Distn (Distortion) Measurement

This measurement field displays the percent of distortion for an audio signal tone.

See “SINAD, Distortion, SNR, AF Frequency, DC Level,” on page 57 for more information.

Operating Considerations

Set the Notch Freq field (on the AF ANALYZER screen) to match the AF frequency used for your distortion measurement.

FM Deviation Measurement

This measurement field displays the deviation of FM signals. This measurement is displayed when the AF Anl In field (on the AF ANALYZER screen) is set to FM Demod or FM Mod.

See “Displaying AF Measurements” on page 57 for more information.
