7 / 40 page AN569 Rev. 0.3 7 3.5. FM Limiting –3 dB 3.5.1. Description The test measures the RF input level when audio output level drops by 3 dB from the standard level. 3.5.2. Conditions/Procedure 1. Connect test equipment as shown in Figure 1. 2. Configure the tuner in standard configuration. 3. Configure the audio analyzer: a. Select Analyze. b. Set Function = THD+N/SINAD. i. Set Measurement Mode = SINAD. ii. Set Unit = dB. iii. Set Filter = A-weighting. iv. Set Frequency Limit Low = 300 Hz. v. Set Frequency Limit High = 15000 Hz. 4. Configure generator: a. Set carrier frequency = 98 MHz. b. Set RF level = 94 dBμV. c. Select FM Modulation. i. Set FM Deviation = 22.5 kHz. ii. Set Source = LFGEN. iii. Set LFGEN frequency = 1 kHz. d. Enable modulation. e. Enable carrier. 5. Record the audio output level (dBV) = VAUDIO0. 6. Adjust the signal generator RF level VRF0, until audio output level VAUDIO1 = VAUDIO0–3. 7. FM limiting –3 dB (dBµV) = VRF0. 3.5.3. Pass Criteria FM Limiting sensitivity for –3 dB audio level drop should be no more than 3 dBµV. |
