FM TUNER SECTION
Frequency Range:
Input level is expressed as the reading in open-circuit
of 75-ohm source impedance signal generator.
1. Usable Sensitivity (Mono, 98MHz)
2. S/N Ratio (60dBµ, IHF wtd)
3. THD (60dBµ, L=R, 75KHz Dev. for AH, 40KHz Dev. for C)
4. IF Rejection (10.7MHz)
5. Image Rejection (119.4MHz)
6. Capture Ratio (40dBµ)
7. AM Suppression (60dBµ, 100%mod FM, 30%mod AM)
8. Pilot Suppression (60dBµ)
