Buttons

	This button indicates that the current real-time settings have been applied to the instrument—no action is required. This button is not available when the Apply Needed button is active.
	This button displays in place of the Setting Current button. It indicates that the instrument settings are not current and need to be updated with the new software settings. Click this button to update the instrument's settings. [:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:APPLy [:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:APPLy?

2. AUX Port General Settings

State

Choice: On|Off

Default: On

Enables or disables the Aux Port General Settings. When disabled, all data sent to the AUX port will be ignored by this I/Q channel.

3. Multiplexed Mode Setup

First Address

Choices: Group 1 to Group 15

Default: Group 1

Selects an additional address (different from a broadcast address) to receive the AUX I/O data. The data that comes with this address value is transmitted to this I/Q channel.

This setting is inactive (grayed out) unless Multiplexed is the AUX IO operating mode.

Second Address

Choices: Group 1 to Group 15

Default: Group 2

Selects another additional address (different from a broadcast address) to receive the AUX I/O data. The data that comes with this address value is transmitted to this I/Q channel.

This setting is inactive (grayed out) unless Multiplexed is the AUX IO operating mode.

4. Dedicated Mode Setup

Aux Port Pin

Choices: Unassigned|AUX0|AUX2|AUX3|AUX4|AUX5|AUX6|AUX7|AUX8|AUX9|AUX10|AUX11

Default: AUX1

Selects a serial pin from which the application channel wants to receive AUX port data.

This setting is inactive (grayed out) unless Dedicated is the AUX IO operating mode.
