Note 33: AM Suppression Ratio
(1) Set SW1 to b, SW2 to a and SW6 to a, and input SIG11 to Tp20 (SW5-b).
(2) Measure Tp3 output amplitude (V AMR). Determine the AM suppression ratio using the following
equation.

Note 34: FM Audio S / N
(1) Set SW1 to b, SW2 to a and SW6 to a, and input SIG3 to Tp20 (SW5-b).
(2) Measure Tp3 output amplitude (V SNF). Determine the FM audio S / N using the following equation.

Note 35: FM Audio Distortion
(1) Set SW1 to b, SW2 to a, SW2 to a and SW6 to a, input SIG11 to Tp20 (SW5-b), and set f0 to 6.0MHz.
(2) Measure distortion in Tp3 output.
Note 36: Detection Band Width
(1) Set SW1 to b, SW2 to a and SW6 to a, and input SIG11 to Tp20 (SW5-b).
(2) Gradually increase input frequency from 6.0MHz and measure the input frequency (+FG) at which Tp3
output amplitude reaches 3dB. The reference value (0dB) is the Tp3 output amplitude when f0 is
6.0MHz.
Note 37: SIF AM Detection Output, Input Sensitivity and Maximum Input
(1) Set SW1 to b, SW2 to b, and SW4 to c, and apply pin 35 to 5V (SW6-b) and input SIG13 to Tp7.
(2) Measure the Tp4 output amplitude (VoAM).
(3) Gradually lower the input level and measure the input level (VAin) at which Tp4 output amplitude reaches
3dB. The reference value (0dB) is the Tp4 output amplitude when input signal amplitude is 90dBV.
(4) Gradually raise the input level and measure the input level (VAinMAX) at which Tp4
output
amplitude reaches 0.5dB. The reference value (0dB) is the Tp4 output amplitude when input signal
amplitude is 90dBV.
Note 38: AM No-Signal Level
(1) Apply 5V to pin 35 (SW6-b), set SW2 to b and SW4 to c, and with no input, apply 3V to Tp5.
(2) Measure Tp2 DC voltage.
