S1. SIF limiting sensitivity . . . . . . . . . . . . . . . . . . [Vli(lim)]
(1) Apply the VCC voltage to the external AGC, IF AGC (pin 17).
(2) fs = 4.5MHz fm = 400Hz
F = ±25kHz (SIF input)
(3) Set the SIF input level to 100mVrms and then measure the level at test point D.......V1
(4) Lower the SIF input level until V1-3dB occurs. Measure the input level at that moment.
S2. S4. FM detection output voltage, distortion factor . . . [VO(FM, THD]
(1) Apply the VCC voltage to the external AGC, IF AGC (pin 17).
(2) fs = 4.5MHz fm = 400Hz
F = ±25kHz
(SIF input Vi=100mVrms)
(3) Assign the level at test point D to the FM detection output voltage and measure the distortion factor.
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)
C2. SIF converter maximum output level . . . . . . [Vmax]
(1) Internal AGC
(2) fp = 45.75MHz CW; 10mV (VIF input)
fs = 41.25MHz CW; 10mV (First SIF input)
(3) Measure the 4.5MHz component at test point E (MIX output). .........Vmax(dB
V)
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, the SW1 must be ON.
