Channel:
Specifies the channel number for dialog settings. Each channel is configured individually. The
drop-down list illustrates the channels that currently have measurements. There must be at
least one displayed trace for the test set I/O Interface to function.
Channel Control Label:
Specifies the label to be displayed on the network analyzer screen during the channel sweep.
Before Sweep Start – After Sweep End Tabs:
Commands (GPIB, I/Os and Dwell) can be sent Before Sweep Start and After Sweep End.
However, they are configured and enabled separately on the Interface Control dialog box. For
example; to send a command before and after a network analyzer sweep, the Enable Interface
Control check box must be selected and commands entered in both the Before Sweep Start
and After Sweep End tabs. The Before Sweep Start data is sent before the first trace on the
channel begins sweeping. The After Sweep Start data is sent after the last trace on the channel
sweep is completed.
Dwell After Command:
Specifies a wait time, in milliseconds, after all commands to all interfaces are sent. Any positive
integer is allowed. This is used to allow all external devices to settle before beginning a
measurement. An erratic trace could indicate that more settling time is necessary.

Provides I/O interface control through the rear panel of the network analyzer. Refer to the
analyzer’s Help menu for further information.
Reset All:
Sets all fields on all channels to their default values.
Save and Recall:
Saves and recalls the contents of the dialog box. If the Interface Control dialog box is
populated with settings during an Instrument State Save, the settings are automatically
recalled with the instrument state settings. Interface control uses an *.xml file type. An
example file is stored on the network analyzer hard drive. You can recall it into the dialog, or
you can open and edit it with a word processor, such as Word Pad.
OK:
Applies the settings and closes the dialog box.
Cancel:
Does not apply changes that were made and closes the dialog box.
Help:
Provides additional information for using the interface control application.
