    • An acquisition apparatus for a test and measurement instrument including a splitter configured to split an input signal into a plurality of split signals, a plurality of oscillators, each oscillator configured to generate a periodic signal, a plurality of combiners, each combiner configured to combine an associated plurality of the periodic signals into an associated signal combination where at least one of the signal combinations is substantially non-periodic. The apparatus also includes a plurality of mixers, each mixer configured to mix an associated split signal and an associated signal combination into an associated mixed signal, a first digitizer configured to digitize an associated split signal, and a plurality of second digitizers, each second digitizer configured to digitize an associated mixed signal.
    • 一种用于测试和测量仪器的采集装置,包括分配器,其被配置为将输入信号分割为多个分离信号,多个振荡器,每个振荡器被配置为产生周期性信号,多个组合器,每个组合器被配置为组合 相关联的多个周期信号转换成相关联的信号组合,其中信号组合中的至少一个基本上是非周期性的。 所述设备还包括多个混频器,每个混频器被配置为将相关联的分离信号和相关联的信号组合混合成相关联的混合信号,配置为数字化相关联的分离信号的第一数字转换器和多个第二数字化仪,每个第二数字转换器 配置为数字化相关的混合信号。
