Channel Data and Properties

Scaling the Channel Data

You can scale the defined channels using the Channel Scaling pane. In particular, you can modify

  • The horizontal scaling and offset for all display components.

  • The vertical scaling and offset for one or more channels. To simultaneously modify the vertical scaling for multiple channels, select the desired channel names in the list box.

    Additionally, using the On/Off button, you can add or remove the selected traces from the Oscilloscope.

As shown below, the horizontal scale is changed to approximately 5 ms/div, and the vertical scale is modified to maximize the trace amplitudes. Note that the horizontal and vertical scaling information is shown at the bottom of each display component.

To specify a precise horizontal scale or offset, you modify the associated display properties. To specify a precise vertical scale or offset, you modify the associated channel properties. You can access these properties using the Scope Editor and the Channel Editor, respectively. You open these editors with the Edit menu or a right-click menu. Note that all displays use the same horizontal offset and scale.

Configuring Channel Properties

There are two sets of properties associated with the Channel Scaling pane:

  • Channel pane properties — Properties associated with the controls and labels that make up the pane

  • Channel properties — Properties associated with the hardware, math, and reference channels that are listed in the pane

For descriptions of all channel properties, click the Help button of the appropriate GUI editor.

Channel Pane Properties

You can change the characteristics of the controls and labels that make up the pane with the Scope Editor GUI. To open this GUI, select Scope from the Edit menu, choose the Scope Properties pane, and select Channel Scaling from the Select scope components list box. The Scope Properties pane is shown below.

Channel Properties

You can change the characteristics of the hardware, math, and reference channels that are listed in the pane by configuring their channel properties. You can access the channel properties these two ways:

  • Property Inspector — Place the mouse cursor in the Channel Scaling pane, right-click, and select Edit Properties from the menu.

  • Channel Editor GUI — Select Channel from the Edit menu, and then choose the Channel Properties pane.

For this example, use the Channel Editor GUI to modify the marker characteristics for both CH0 and CH1. The steps are

  1. Select both hardware channels from the Select the channels list box.

  2. Specify a circular symbol for the Marker property, and specify an interval of 4 for the MarkerInterval property.

The Channel Properties pane is shown below.
