AF Analyzer Distortion, SINAD, and SNR Accuracy Performance Test 16
1. Press the PRESET key on the Test Set.
2. Access the AF ANALYZER screen and set Filter 2 to 15 kHz LPF.
3. Set the AF Anl In field to Audio In.
4. On the Function Synthesizer set ch A Freq to 1 kHz and the level to 1 V DESTN
Out1.
5. Set ch B Freq to the Harmonic frequencies shown in the PTR DESTN Out1
"AF Analyzer Distortion, SINAD and SNR Accuracy Performance Test 16" on
page 386), and the AFGen2 level to the distortion product levels shown in the PTR.
6. Measure the distortion and SINAD at each frequency and level, and compare the
measured results with the limits shown in the PTR.
7. Measure the SNR (Signal to Noise Ratio) at each harmonic and level shown in the PTR.
Compare the results to the limits shown in the PTR.
