DCAで消光比測定

さてうまく行かないんだけど・・・コマンドとその組み合わせが英語だから分からないのではなくマニュアルの作りが悪い。悪いのは皆周りである。

/*
* Funciton Name: acquireSerial
* Parameters: none
* Returned value: int - the time to acquire the data
* Description: This routine turns on channel 1, performs an autoscale, acquires 
* 200 waveforms, performs a mask test, and then performs the measurements.  The
* process is then repeated for channel 2.
