1. For specified frequency ranges between 60 and 3000 MHz, Channel BW ≤ 1 MHz.
2. FM Rate: 400 Hz, 1 kHz, 10 kHz; FM Modulation Index: 1 to 2000
3. AM Rate: 400 Hz, 1 kHz, 10 kHz; AM Depth: 1% to 99%
4. PM Rate: 400 Hz, 1 kHz, 10 kHz; PM Deviation: 1 to 100 rad
5. Peak deviation, modulation index (“beta”), and modulation rate are related by Peak Deviation = Modulation Index × Rate.
6. SINAD [dB] can be derived by 20 x log10 (1/Distortion), SINAD bandwidth: (Channel BW)/2.
