Before Sweep Start – After Sweep End Tabs: (6)
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 PNA-X 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 PNA-X. Refer to the PNA-X 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 PNA-X 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.
