(mhz) 500 (mv) the compensation values are derived from gmod and from gdemod1 and gdemod2 of measurement nos. 48 and 50. standard mode compensation value : g c1 = 20log [g mod (mhz/mv) x g demod1 (mv/mhz)] hi-8 mode compensation value : g c2 = 20log [g mod (mhz/mv) x g demod2 (mv/mhz)] next, in order to set the sg41 carrier frequency, adjust v car so that the y rf out (pin 43) output of the cxa1207a in standard mode is 4.8mhz and in hi-8 mode is 6.7mhz. in the above state, measure the i/o gain for the sg54 (200mvp-p/300khz) input and p7 (pin 7 demod out), with the gain for standard mode being g lpf10 and for hi-8 mode g lpf20 . using these measured values and compensation values, the low frequency gain for demod lpf is determined using the following equations: standard mode : g lpf11 = g lpf10 - g c1 (db) hi-8 mode : g lpf21 = g lpf20 - g c2 (db) 7 41 54 43 cxa1207a rec mode sw41 yrfin lim demod lpf demod out p7 cxa1700a to be measured car 1 4700 4700 sg54 v car (sg41) yrfout fm mod
