M52334FP
IM Intermodulation
1. Input SG11 into VIF IN, and measure EQ output TP3A with an oscilloscope.
2. Adjust AGC filter voltage V13 so that the minimum DC level of the output waveform is 1.0 V.
3. At this time, measure, TP3A with a spectrum analyzer. The intermoduration is defined as a difference between 0.92
LIM Limiting Sensitivity
1. Input SG17 (Vi
2. Lower the input level of SG17, and measure the level of SG17 when the VoAF level reaches 3 dB.
AMR AM Rejection
1. Input SG18 into SIF input, and measure the output level of AF output TP11. This level is named VAM.
2. AMR is;
AF S/N
1. Input SG19 into SIF input, and measure the output noise level of AF output TP11. This level is named VN.
2. S/N is;
