Tool Bar

Main Tool Bar

The main tool bar provides provides buttons for frequently used steps in configuring the system to play the waveforms.. Click each tool bar item to view its description.

Feature/Application Tool Bar

The feature/application tool bar provides options when configuring playback, real time, I/O settings, or instrument settings.

 

New Configuration    

Displays the Configuration Browser in the tree view where you can select a new configuration. The configurations displayed depend on the hardware and licenses installed in your instrument. Selecting a configuration in the tree view displays the block diagram for the configuration in the parameter view.

Download Panel

Displays the Download panel where you can view the names and status of waveform files or dynamic fading scenario files, and then select them for downloading. The dynamic fading scenario files are only active when you have enabled dynamic fading; otherwise, they are greyed out.

Calibrate Power

Ensures accurate power for the current configuration. You should run a power calibration any time you perform an action that changes the RMS value of the output signal, for instance, turning AWGN on or off, turning fading on or off, or changing waveforms. To run the output power calibration, click the Calibrate Power button on the Tool Bar. You can set the power calibration to manual or auto by clicking System > Calibration > Power Calibration in the menu bar.

Power Calibration Considerations
  • Power calibration uses the RMS value of the input signals at the time the power cal is run to establish the output power of the system.
  • In any configuration where ALC is off (configurations with fading or summing), if the input RMS value changes after power cal, the signal output power (but not the noise power) will also fluctuate accordingly. This power variation is not reflected in any display. It is particularly important when using external inputs, that you make sure that the initial RMS value is a true representation of the average value expected during the measurement.

 

If the system is playing, click Stop before running Calibrate Power.

Play

Triggers the PXB to start generating all the downloaded waveforms (or data from a connected external input device) for the currently loaded configuration. If the trigger source is set to Bus, no waveform will be played until you send the *TRG command. If the trigger source is set to Hardware, no waveform will be played until the first hardware trigger is received.  

Play is enabled once a configuration with external input has been loaded. For all other configurations, Play is enabled once you have completely downloaded your waveform files to each BB Gen block in the PXB. Waveforms cannot be updated while the instrument is playing.

Stop    

Triggers the PXB to stop playing all the downloaded waveforms or signal data for the currently loaded configuration.

Stop is enabled once you start playing the waveforms or signal data.

Restore Default Settings

Returns the settings of the current pane: playback, baseband generator or I/O settings to their default values.

Block Diagram

Displays the Block Diagram and the External Instrument Table for the currently loaded configuration.

Copy and Paste

Allows you to quickly duplicate settings from one resource to another like resource. Suggested uses include:

The Copy button is enabled once your configuration is loaded and the settings are displayed in the parameter view. To copy a resource's settings:

  1. Navigate to the ClosedSettings Browser and select a resource.

  2. Edit the displayed resources's settings if desired.

  3. Click the Copy button. After Copy is selected, the settings are stored until either another resource within that group is copied or the user interface is closed.

The Paste button is enabled once you have copied the settings of one resource within the selected group. To paste a copy of stored settings to other settings within a group or to like resources in another configuration:

  1. Click the Paste button. The Paste dialog box that appears depends on the type of settings you have copied. For instance, if you have copied Playback settings, the Playback ClosedPaste dialog box is displayed.

     


     

  2. Select the destination resources in the list.

  3. Click OK to overwrite each selected resource with the stored settings. If you click the Cancel button, nothing is pasted, and the dialog box closes. Only valid destination resources appear in the Paste dialog box.

Show/Hide Help

Displays a short definition at the bottom of the pane when you click a parameter setting with Show Help active. Toggling the button hides the help information.
