写入每次扫描波形数据的大/小值。
当记录道设置为大/小保持模式时，每次执行扫描时，数据
在各个测量点与先前的测量进行比较，并且
写入较高电平（大保持）或较低电平（小保持）的测量值。
如果要测量变化的波形的大值或小值
每次执行扫描时，将要测量的轨迹设置为大/小保持
模式并执行重复扫描。
数据区侧面的跟踪显示显示为“大保持”或“小保持”。
请注意，当显示波形时，噪声屏蔽软键设置适用，并且
检测到大值或小值时不受影响。
滚动平均模式（滚动平均模式）
写入每次扫描期间波形数据的滚动平均值。
当轨迹设置为滚动平均模式时，每次进行测量时，滚动
计算当前测量值和过去测量值的平均值
更新测量数据。平均数设置在2到
数据区侧面的轨迹显示变为“ROLL AVG”

Writes the maximum/minimum values of the waveform data for each sweep. When a trace is set to MAX/MIN HOLD mode, each time a sweep is performed, the data at the individual measurement points are compared with prior measurements, and the measurement with the higher level (MAX HOLD) or lower level (MIN HOLD) is written. If you want to measure the maximum or minimum value of a waveform which changes each time a sweep is performed, set the trace you want to measure to MAX/MIN HOLD mode and perform REPEAT sweeping. The trace display at the side of the data area appears as “MAX HOLD” or “MIN HOLD”. Note that the NOISE MASK soft key setting applies when a waveform is displayed, and is not affected when a maximum or minimum value is detected. ROLL AVG Mode (Rolling Average Mode) Writes the rolling average values of the waveform data during each sweep. When a trace is set to ROLL AVG mode, each time measurement is performed the rolling average of the current measurement and past measurements is calculated, and the measurement data are updated. The number of averagings is set in the range of 2 to 100. The trace display at the side of the data area changes to “ROLL AVG”
