Abstract: Various embodiments are described of devices and associated methods for processing a signal using a plurality of vector signal analyzers (VSAs). An input signal may be split and provided to a plurality of VSAs, each of which may process a respective frequency band of the signal, where the respective frequency bands have regions of overlap. Each VSA may adjust the gain and phase of its respective signal such that continuity of phase and magnitude is preserved through the regions of overlap. The correction of gain and phase may be accomplished by a complex multiply with a complex calibration constant. A complex calibration constant may be determined for each VSA by comparing the gain and phase of one or more calibration tones generated with each region of overlap, as measured by each of the VSAs.

Abstract translation: 描述了使用多个向量信号分析器（VSA）处理信号的设备和相关方法的各种实施例。 输入信号可以被分离并提供给多个VSA，每个VSA可以处理信号的相应频带，其中各个频带具有重叠的区域。 每个VSA可以调整其相应信号的增益和相位，使得通过重叠区域保持相位和幅度的连续性。 增益和相位的校正可以通过复数乘以复合校准常数来实现。 可以通过比较由每个VSA测量的每个重叠区域产生的一个或多个校准音调的增益和相位来为每个VSA确定复校正常数。
