Power Supplies – Electronics Explorer
This instrument has two main areas: the control area and the plot window.
The control area contains power supplies with adjustable voltage and current.

See Menu in Common Interfaces.
The control area lets you adjust the settings for the various voltmeters and power supplies.
- Master Enable: the master ON/OFF switch for the power supplies and reference voltages.
- On/Off: enable switches for each supply.
- Voltage and current fields: let you adjust the values for the power supplies by either selecting a value from combo box, or typing it in. Below the adjustment fields, the voltage/current reading is shown.
The history plot has the following components:
- Add: opens a window. Select an item from the list and press the Add button (or double-click) to add it to the plot list. Using the function field, a custom mathematic channel can be created.
- Remove the selected item(s) from the list.
- Edit the currently selected list item.
- Show: enables or disables columns displaying the minimum and maximum levels from the history plot.
- History: specifies the time span for the plot. Under the history options, update rate and the number of samples can be specified.
- Clear: clear the history plot.
For each channel, the color and scaling option can be specified: auto scaling based on the extremes from the plot history or manually specified offset and range.
See Script in Common interfaces. The local variables are the elementary logger channels, which vary depending on the device.
Example functions:
- Vmtr2 - Vmtr1
- 4.7 / (Vmtr1 + VccVoltage / 2)
