1、Universal Oscilloscope 通用波形测试The universal oscilloscope can record up to two signals. It can be triggered to the signal of one of the displayed channels or to a third channel. At the inputs, the connections A1 to A6, as well as the PickUp and universal input, are available. For standard measurements
2、 there are control images. When you call up a control image, the universal oscilloscope is adjusted in a way which allows you to measure immediately and without further adjustments. The control image itself is shown as a reference on a channel (A or B). Comparison enables faults to be detected easil
3、y.通用波形测试可提供两个波形通道进行测线，通过触发设定功能可选择相应通道或第三组外挂信源。连接 A1 至 A6 线组、或传感器和通用输入源。标准波形对比测试由标准波形库控制功能设定。预设值提供即时信号动态显示。“标准波形库控制”功能自动提供相应标准波形供对比测试。Channel Settings通道设定Time Base时间座标Trigger Setting引发设定External Trigger外部引发Pre-Settings / Control Images预设 / 标准波形库控制功能Zoom Representation画面缩放控制Online Representation实时显示Me
4、mory Representation储存图像回放Printing列印功能Channel Settings 通道设定In the highest input field, you can enter a text which describes your signal. 自行输入通道性质或名称Signal Input: 信源输入：A1.

5、, 5V, 10V, 20V, 50V per division (per DIV). If an input range of 1 V/DIV has been set, 10 Volts can be displayed (10 vertical divisions)（每分格计算）.输入范围设定是（1V / DIV），等于垂直行格设定是 1V，显示栏共计 10 行等于总数是 10V。Coupling Type 耦合型式 :This choice box group allows you to set the signal coupling type:选择窗提供设定信号耦合型式：AC: al
6、ternating current coupling 交流耦合DC: direct current coupling 直流耦合GND: The signal is substituted by a ground level, allowing you to accurately adjust the signal zero line.

7、input signal is inverted.反向输入信号。Stop: This choice box allows you to freeze the channel representation. The channel signal image is no longer updated. 停止：停止信号输入画面功能。on / off: This choice box allows you to switch off the appropriate channel.开 /关 ：启动相关通道功能。Y-Offset: By means of this shifting bar you ca
8、n shift the signal 0-Volt-line. The choice box allows you to shift this shifting bar back into centre position. Y 设定：可移动“0 伏线”，启动中位视窗。Time Base 时间座标Possible time bases 正时座标 : 1 s, 0.5 s, 0.2 s, 0.1 s,“秒”50 ms, 20 ms, 10 ms, 5 ms, 2 ms, 1 ms,“微秒”500 us, 200 us, 100 us, 50 us, 20us per division (DIV).
9、“毫秒”分格。If a time base of 1s/DIV has been set, 10s are displayed per image (1 image = 10 divisions DIV).时间座标设定 1s / 分格，视窗共 10 格共计 10s 显示。In addition to this, there is also the 100% setting. In this case, the display is automatically set in such a way that the period of time between two trigger events
10、 exactly fills the 10 divisions.尚有 100% 设定：可自动显示完整影像曲线，单组图像时间平均分成 10 格。Trigger Setting 触发设定Trigger Source 触发来源 :Channel A or B 通道The trigger is generated from the signal displayed on channel A or B. 选择由A或B通道引入的信号触发显示Internal Trigger 内部引发Signal-independent triggers are generated in the HMS 990.

12、irst triggers are received from the trigger signal. This facility is designed to make the universal oscilloscope connection or setting easier for you. For example, if a trigger is set negatively, a purely positive signal would not generate any triggers and therefore would not result in a pictorial r
13、epresentation.使用通道 A、B 或外挂传感器，首先“内部引发”模式启动；记录开始接收第一个引发信号。此项设计是方便用者在通用示波器连接或设定时较为容易。例如：引发设定为“负”，而信源是“正”的话便不能显示。Trigger Level 触发水平The trigger level can be changed using arrow symbols. For positive percentages, the figure refers to the positive signal content. If you press the +/- switch, the sign in t
14、he entry window changes and the trigger level is switched over accordingly.按“箭头”可选择引发水平。数字显示“正”极 %。按“+/-”键转换极性。Trigger Edge 触发边缘By selecting a pos. or neg. choice box, you can determine the edge onto which you wish to trigger.经由选择 “+”或“-”功能窗，用者便可随意连结引发边缘。Positive 正 : A trigger is tripped when the tr
