CHANNEL Menu
Chan. Max
When multiple channels are displays, use the Channel Maximum button to maximize the active channel to fill the display area. Clicking a second time returns to the prior multi-channel view.
Chan. Next
When multiple channels are displayed, the Channel Next button activates the next higher channel number. When the highest channel number is reached, the next click activates channel 1 (one).
Chan. Previous
When multiple channels are displayed, the Channel Previous button activates the next lower channel number. When channel 1 (one) is reached, the next click activates the highest channel number.
# of Channels
Select displays the Number of Channels field toolbar below the icon toolbar. The toolbar allows the user to set the number of displayed channels in discrete values of 1 (one), 2, 3, 4, 6, 8, 9, 10, 12, or 16 channels. If other channel settings are applied (5, 7, 11, 13, or 14), the instrument applies the next permitted channel setting. The Channel Layout (described below) is automatically set to the number of selected channels. If the instrument is in 100,000 point mode, only 1 (one) channel is available.
Chan. Layout
The Channel Layout button displays the CHAN. LAYOUT menu which defines how multiple channels are displayed on the screen.
CHAN. LAYOUT Menu
The CHANNEL LAYOUT menu allows the user to select from 22 selectable channel views. The channel view buttons are not labeled, but instead provide a representative icon of each view configuration. For example, the Single Channel View button provides a channel view where one channel is displayed in one display area. Once the desired view is selected, click the Back button at the bottom of the CHAN. LAYOUT menu to return to the CHANNEL menu. Note that CHAN. LAYOUT menu setting and the # of Channels setting on the CHANNEL menu are linked. Changing the number of channels selects an appropriate channel layout. Changing the channel layout where the number of displayed channels changes, changes the number of channels set on the CHANNEL menu.

The Chan. Layout buttons do not have labels, but do have tool tips that appear if the mouse pointer is hovered over the button. The selected channel layout view is indicated by the button selected icon. For VNA programmatic control, note also that each channel layout is described by the SCPI appropriate SCPI parameter. For example, to program a three across channel layout, use the R1C3 parameter.
The long CHAN LAYOUT menu is immediately below. The names of the different channel layout displays are shown in the Table: Channel Layout Options below.
