    • Time correlation of signal to distortion characteristics is achieved by acquiring time domain data for a frequency band representing a communication signal, the communication signal having multiple channels. The time domain data is simultaneously converted to frequency and demodulation domain data in sequential time blocks. The frequency and demodulation domain data are processed to obtain respectively frequency and demodulation domain measurements. The resulting measurements are displayed simultaneously as a function of time for all the time blocks and/or for a selected one of the time blocks. An ACLRogram display provides a display having a time axis and a frequency axis in the form of bars spanning the frequency band for each time block with each bar being divided into frequency sub-bands representing a main channel and adjacent side channels, the shading of each segment of the bar representing a measurement value for that segment.
    • 通过获取表示通信信号的频带的时域数据,通信信号具有多个信道来实现信号与失真特性的时间相关性。 时域数据同时转换为连续时间块中的频率和解调域数据。 对频率和解调域数据进行处理,以获得频域和解调域测量结果。 所得到的测量值作为所有时间块和/或所选时间块的时间的函数同时显示。 ACLRogram显示器提供具有时间轴和频率轴的显示器,每个时间块的频带横跨频带,每个时钟块被分成表示主频道和相邻侧频道的频率子带,每个 条的段代表该段的测量值。
