AD9850 DDS VFO Premixed版にｽﾌﾟﾘｯﾄ機能を追加した。これで一通りの機能が揃った事になる。本来ならば、全ての機能を織り込んで、Version 1.0とすべきだが、他との識別の為、Version 1.1bとした。ｽﾌﾟﾘｯﾄ操作は、split SWを押し、Xと表示が出たら、ﾛｰﾀﾘｰｴﾝｺｰﾀﾞで値をｾｯﾄするのみである。他のVFOをｾｯﾄする必要もない。簡単にSPLIT運用ができる。
回路図である。SPLITｽｲｯﾁを追加した以外、Ver1.1aと同じ。
Program
SPLIT機能は、RIT機能のｻﾌﾞﾙｰﾁﾝを使ってﾒﾓﾘｰ消費をおさえた。SPLITとRITは排他的な関係で、直感的なｵﾍﾟﾚｰｼｮﾝが出来るが、RIT制限範囲 = SPLIT制限範囲である。
最大STEP値が、100kと50kを選択出来るよう、条件付ｺﾝﾊﾟｲﾙﾌﾟﾛｸﾞﾗﾑとした。STEP 100kにする時Step_100k=1。また、STEP 50kにする時、Step_100k=0と書き換えれば良い。(下記ﾌﾟﾛｸﾞﾗﾑは、STEP 50k)
