Controlling the Test Set
Channel: (4)
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: (5)
Specifies the label to be displayed on the network analyzer screen during the channel sweep.
Before Sweep Start – After Sweep End Tabs: (6)
Commands (GPIB, I/O’s 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: (7)
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.
Handler I/O Control and Aux I/O Output Voltage: (8)
Provides I/O interface control through the rear panel of the network analyzer. Refer to the network analyzer
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.
