FEATURE DESCRIPTION
Communications
Test
(action button)
This feature can be used only when the <Output Type> is RS-232 or IEEE-488.
Press this button to send the set <Initialization Commands> and a single target flow.
When the option is first selected, a dialog box prompts for the desired target flow.
A
<Spy Window> will display with the command response information used
(see Section 6.7.7). This feature is designed to provide on the spot troubleshooting of
the remote command setup. If a command is not properly entered or the response
format is not correct, the problem should be visible in the spy window. Use the
<Remote Communications> tool for further troubleshooting (see Section 13).
10.3.6 [FLOW CONTROLLER] TAB
The [Setup] , [Hardware] , [Controller] tab is used to manage the Hardware Definitions of
flow controllers that are included in the Test Definition [Control] tab, <Controller> drop down
list (see Section 10.2).
The [Controller] tab provides a list of the available flow controllers, displays complete information
on the selected controller, allows the controller to be edited or a new controller to be created.
To select a flow controller Hardware Definition to view, single click on the controller name and
serial number in the
<List> display panel (upper left-hand corner). To edit an existing flow
controller, double click on the controller listing or click on the <Edit> toolbar function with the
desired controller highlighted. Double clicking the controller listing, clicking on the <Edit>
toolbar function or clicking on the <New> toolbar function causes the <Edit Flow Controller>
or <Add Flow Controller> pop-up to appear. These pop-ups are identical but differentiated
by name to make it clear which task is currently being performed.
The <Edit Flow Controller> or <Add Flow Controller> pop-ups allow a controller to be set
up from scratch or edited from an existing one.
The basic setup of the flow controller is very similar to setting up a DUT that is a
flow controller. The flow controller setup requires selections on three different tabs
<Range> ,
<Gas> and <Interface> .
The purpose of the flow controller Definition fields and settings as well as instructions on how to
use them are provided in Table 39. When creating a new Definition, all the fields come up
blank. When editing an existing Definition, the fields come up populated with the information
on that device. When editing is complete, click
<OK> to save changes.
