AF Freq Measurement

The AF frequency measurement is the audio frequency of the signal present at the input selected in the AF Anl In field (on the AF ANALYZER screen). Four dashes (- - - -) indicate that no audio frequency is present to measure.

See “SINAD, Distortion, SNR, AF Frequency, DC Level,” on page 57 for more information. See also “AF Anl In” on page 185.

DC Level Measurement

This measurement field displays the dc voltage entering at the source set in the AF Anl In field (on the AF ANALYZER screen).

See “SINAD, Distortion, SNR, AF Frequency, DC Level,” on page 57 for more information. See also “AF Anl In” on page 185.

Operating Considerations

When the AF Anl In field is set to FM Demod or AM Demod, the unit-of-measure is kHz (for FM Demod) or % (for AM Demod). For these two settings this measurement indicates the dc modulation component of the received signal.
