C5. OSC leakage (OSC leak)
(1) Internal AGC
(2) fp = 38.9MHz CW; 10mV(VIF input)
fs = 33.4MHz CW; 316
V(First SIF input)
(3) Measure the 6MHz component at test point E (MIX output). ..........V6(dB
V)
(4) Measure the 500kHz component at test point E (MIX output). .......V0.5(dB
V)
(5) Perform the following calculation.
Carrier suppression ratio OSCleak(dB)=V6 - V0.5
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 38.9MHz.
Note 2)
Unless otherwise specified, the SW1 must be ON.
