Electronics Explorer Board - Using the Power Supplies

这Electronics Explorer Board power supplies have many more capabilities and options than the Analog Discovery 2.

如果您想要一些帮助，让您的电子探索器板设置和校准或安装波形，请查看此快速启动Instructables collection. The calibration is similar to the Analog Discovery 2, and I recommend you calibrate your Electronics Explorer board before using it. You will need to have a high-wattage (≅10W) resistor between 10-50Ω and a quality voltmeter to finish the calibration.

拥有电子探索器板并设置了波形后，请单击“供应”按钮，打开电源。

Figure 2. Power supplies button.

This will open the power supplies window.

Figure 3. Power supplies window.

At the top you have three options: “File”, “Control”, and “Window”.

  • “File” lets you节省当前的电源设置是一个新项目，您可以Open该项目将电源设置为已保存的设置。你可以出口the power supply settings, either as an image or as raw data in *.csv, *.txt, or *.tdms format. You can alsoClosethe power supplies window from here.
  • “控制”可访问Run和Stop功能。
  • “Window” lets you view other波形您打开的工具，主波形屏幕或帮助window.

在此下方，您拥有四种电源类型中每一种的控件。

Figure 4. Power supply types.

在左上方是Master Enable，它将打开/关闭任何在该按钮下面列表中具有复选标记的电源频道。任何未检查的频道都不会使用主启用按钮打开。

Figure 5. Power supply channel list.

这re are four boxes to the right of the enable boxes.

Figure 6. The four boxes to the right of the power supply channel list.

在左上方是Positive Supply(VP+). You can set the voltage to any value between 0 and +9V out to 3 decimal places. You can also set the max current limit to any value between 0 and 1.5A out to 3 decimal places. Once VP+ is enabled and turned on, the Electronics Explorer Board will send back real time voltage and current data, which will be displayed in the box below the drop-down menu.

低于正供应的是负供应（VP-）。参数限制与FRO VP+相同，除非负面而不是正面。一旦启用VP-并打开，还将显示实时数据。

To the top right you have your固定供应(Vcc)。您可以选择+ 3.3 vor +5V. This is really useful for powering microcontrollers, microprocessors, or FPGA chips that require a steady power supply. Real time voltage and current data is displayed below the drop-down menu. You cannot limit the current available on this channel.

Below the Fixed Supply are the参考波动（VREF1和VREF2）。您可以在-10V和 +10V之间设置这些值。小数精度随使用MV还是V值而异。没有来自电子探索器板监视这些引脚的实时数据。

接下来是绘图窗口。

图7.情节窗口。

在左侧，您可以使用各种指标来监视电路。这价值列显示了最后一个样本的值。

By clicking on the button displayed below, you can select from a list of additional metrics to add to the watch list.图8.其他指标按钮。

Figure 8. Metric display.

Double click on the metric you want to add, then click “Close”. The new metric will appear at the bottom of the list. Note that Vmtrn是电子资源管理器板的独家功能，并指定了板本身的四个内置电压之一。他们参考内部测量电压GND电子探索器板的平面。

单击下面的按钮可让您删除所选的指标或一次清除所有指标。您还可以按键盘上的“删除”以删除突出显示的度量标准。图9.拆除度量。

With a metric highlighted, the button displayed below lets you reassign a metric to that slot. You can have as many instances of the same metric as you want. You can also just double click on a metric to reassign that slot to a different metric.图10.重新分配度量。

这button below will add Maximum and Minimum columns to each metric, next to the Value column. As more samples are taken, these values will change to reflect the max or min value that has been measured by that metric.图11.添加最大和最小列。

这History box sets the total metric history that is viewable in the plot window. You can set this value to most values between 10s and 24 hours. If the value you enter won't work, the plot will auto-correct to the closet value that will work.Figure 12. History box.

这button below lets you change the plot update rate and how many samples are shown in the plot window. Be aware that these two values are tied to the value in the History box, and changes in one will likely affect one or both of the other two.图13.绘图更新率。

这button displayed below will clear the plot window of all metric traces. This can be done at any time, whether the supplies are on or off. New traces will become visible as more samples begin to register.Figure 14. Clear the plot window.

绘图列有一个适用于每个指标的框，可以在图上启用/禁用该特定跟踪。选中框以启用跟踪。

To change the color of the trace clock on the color box in the Color column. Pick your new color from the window that opens and click “OK” to change it.

每个指标都有一个小型齿轮图标，如下所示，在绘图窗口旁边的最后一列中。这使您可以为该特定指标设置垂直图量表。默认设置自动调整，但是您可以设置单位/部门值和偏移值。图15.齿轮图标。

In the top right corner of the plot another small gear icon is displayed. You can add or remove labels to the plot, change the background from black to white, and change the default trace width for all metrics. If you click on a metric, its trace will be slightly wider than the others and will also rise to the top layer of the plot to make it easier to see.Figure 16. Gear icon that will add or remove labels.

最后，在剧情的右上角上方，您会看到一个绿色箭头。这将使情节幻灯片关闭，从而扩大了左侧的度量值列，以使数据更清晰地查看。再次单击它以将绘图窗口打开。即使关闭，该图也将继续更新，并且打开它将根据速率，样本和历史记录设置显示准确的历史记录。Figure 17. Plot slide button.
