Capture and Display Filter Differences

Display and capture filters are activated in different ways. Also, some options for capture filters are not used in display filters. Some options available in capture fil- ters make no sense for display and are therefore not supported:

•Display filters do not use custom counters.

•The action “display” is available for display filters. The actions “capture” and “trigger” and “increment customer counter” are available with capture filters.

•Display filters do not have global settings. Global settings for the capture filter include the test value you can set for each custom counter when they are used as counter conditions and a buffer trigger position.

Activating Display Filters
Activate (load) a display filter by pressing the Load Filter			button on the Filter
Design or Filter States Design toolbar. Deactivate (unload) a display filter by press-
ing the Unload Filter	button on the Filter Design or Filter States Design toolbar
or the Unload Display Filter		button on the Detail View toolbar.

You can keep the display filter ON at all times; if you make changes, the next time you view data in Capture View the new filter will be used immediately. If you already have a Capture View window open for the capture file, select the Refresh...

option from the File menu in Capture View to refresh the view using the new filter.

You can also create and immediately activate a display filter from Multi-QoS tables using the right mouse button.

Activating Capture Filters

The capture filter must be loaded to the hardware module. It is not active until you

press the Load Filter button on the Filter Design or Filter States Design toolbar. It remains active for that module until you unload the filter. Unload a capture filter by

pressing the press the Unload Filter button on the Filter Design or Filter States

Design toolbar. Since capture filters are associated with a hardware module, differ- ent capture filters can be loaded to different modules.

For THGm devices, you can load a filter while capture is in progress. For other devices, you must stop the device before loading the filter.

You can load a filter from Summary View (main window) using the button.

You can also create and immediately activate a capture filter for the current resource from Multi-QoS tables using the right mouse button.
