S3. AM rejection ratio …… [AMR]
(1) Apply the VCC voltage to the external AGC, IF AGC (pin 17).
(2) fs = 4.5MHz fm = 400Hz AM = 30% (SIF input Vi = 100mVrms)
(3) Measure the output level at test point D. ……VAM
(4)
S5. SIF S/N …… [S/N]
(1) External AGC (V17 = VCC).
(2) fs = 4.5MHz NO MOD Vi = 100mVrms
(3) Measure the output level at test point D. ……Vn
(4)
S6. 4.5MHz output level …… [Vsout]
(1) External AGC (V17 = VCC).
(2) fs = 4.5MHz NO MOD Vi = 10mVrms
(3) Measure the output level at test point E. ……Vsout
Note 1) Unless otherwise specified for VIF test, apply the VCC voltage to the IF AGC and adjust the VCO coil so that
oscillation occurs at 45.75MHz.
Note 2) Unless otherwise specified, turn ON the SW1.
