本机体积小重量轻、省电(<4mA),能输出以下电视信号:①当K_1置于V、K_2置于IF时,输出32～38MHz可调中频信号及1频道信号;②K_1置于V,K_2置于L时,输出2～5频道信号;③K_1置于U,K_2置于H时,输出6～12频道信号;④K_1置于U,K_2置于L,输出U段信号。由V_(1.2)构成低频振荡器,其基准频率约为500Hz,用以调制射频输出。V_(1.2)的β值≥40。用V_3构
This machine is small in size and light in weight, power saving (<4mA) and can output the following TV signals: ① When K_1 is set to V and K_2 is set to IF, 32 ~ 38MHz adjustable IF signal and 1 channel signal are output; , K_2 is set to L, the output 2 to 5 channel signal; ③ K_1 set U, K_2 set at H, the output channel 6 to 12 signals; ④ K_1 set U, K_2 set to L, the output U segment signal. By V_ (1.2) constitute a low-frequency oscillator, the reference frequency of about 500Hz, used to modulate the RF output. V_ (1.2) β value ≥ 40. V_3 structure
