    • Two sets of TACs are simultaneously operated by a start pulse, one set of TACs using a photoelectron pulse due to an excited light from a sample as a stop pulse, and the other set of TACs using a photoelectron pulse due to a fluorescence from the sample as a stop pulse. Each TAC outputs a voltage proportional to the time from the start of action to the receiving of the stop pulse and an excitation light shape and a luminescence transient shape are simultaneously measured on the basis of output voltages from the TACs. A variable offset voltage is added to an output of at least one of the two sets of TACs and the excitation light shape and the luminescence transient shape are displayed on a two-picture synthetic display.
    • 两组TAC通过起始脉冲同时操作,一组由于来自样品的激发光作为停止脉冲使用光电子脉冲的TAC,另一组TAC由于来自样品的荧光而使用光电子脉冲 作为停止脉冲。 每个TAC输出与起动作用到接收停止脉冲的时间成比例的电压,并且基于来自TAC的输出电压同时测量激发光形状和发光瞬态形状。 向两组TAC中的至少一个的输出添加可变偏移电压,并且将激发光形状和发光瞬态形状显示在双画面合成显示器上。

    • An analyzer compensation circuit for compensating for the fluctuations in the intensity of the light source or for stains on the windows of cells in an analyzer. A pair of D-A converters are respectively connected to compensating and measuring light detectors. An up/down counter is arranged to count either up or down in response to the output of a comparator. The comparator compares the output of the D-A converter connected to the compensating detector with a reference value and the output of the up/down counter is connected to both of the D-A converters such that the output of the converter connected to the compensating detector is adjusted to be equal to the reference value. Since the other D-A converter is also connected to the output of the up/down counter, the output of the other D-A converter has been compensated for fluctuations in the light intensity or stains on the windows on cells used in the analyzer.
    • 一种分析仪补偿电路,用于补偿分析仪中光源强度或细胞窗口上污渍的波动。 一对D-A转换器分别连接到补偿和测量光检测器。 上/下计数器被布置成响应于比较器的输出而向上或向下计数。 比较器将连接到补偿检测器的DA转换器的输出与参考值进行比较,并且向上/向下计数器的输出连接到两个DA转换器,使得连接到补偿检测器的转换器的输出被调整为 等于参考值。 由于另一个D-A转换器也连接到增/减计数器的输出,所以其他D-A转换器的输出已被补偿了分析仪中使用的单元上的光强度或窗口上的污渍的波动。
