AC/DC Characteristics (cont’d)
1) Channel 6 beat is the interfering product of f
RFpix, fRFsnd - fOSC of channel 6 at 42 MHz.
2) Channel A-5 beat is the interfering product of f
RFpix + fRFsnd - fOSC of channel A-5, fBEAT = 45.5 MHz.
The possible mechanisms are: f
OSC - 2
* fIF or 2 * fRFpix - fOSC . For the measurement VRF = 80 dBV.
