2.场扫描输出电路本机的场扫描输出电路采用日本三洋(SANYO)公司的LA7845N作功率放大。以N101(OM8839PS)的(46)、(47)脚输出的V-、V+激励脉冲经接插件XS403传送至N401(LA7845N)的⑤、④脚,由内部电路激励放大、功率放大后,从它的②脚输出场频锯齿波电流,然后送到场偏转线圈,进行垂直扫描。
2. Field scan output circuit The local field scan output circuit using Japan’s Sanyo (SANYO) company’s LA7845N for power amplification. The V- and V + excitation pulses output by the (46) and (47) pins of N101 (OM8839PS) are transmitted to the ⑤ and ④ pin of N401 (LA7845N) through the connector XS403 and amplified by the internal circuit. After power amplification, ② feet output field frequency sawtooth wave current, and then sent to the field deflection coil for vertical scanning.
