Buttons

This topic describes the buttons found on the various software windows.

Add Instrument

Button Location: Signal Generator Setting window

For the Signal Generator, click this button to add another instrument to the Hardware and Connections Settings tree node. This button is visible while viewing an instrument setting window.

For the PXB, this button is unavailable and shows as grayed out.

Delete Instrument

Button Location: Signal Generator Setting windows

For the Signal Generator, click this button to delete an instrument displayed in the Hardware and Connections Settings tree node. This button is visible while viewing an instrument setting window. Follow this process to delete the desired instrument:

In the Hardware and Connections Settings tree node, click the instrument to be deleted.

The highlighted instrument settings appear in the right window.
At the top of the selected instrument settings window, click the Delete Instrument button.

The software does not allow the deletion of all instruments. If there is only one instrument showing, the software will not allow it to be deleted.

For the PXB, this button is unavailable and shows as grayed out.

Test Connection

Button Location: Signal Generator and PXB Setting windows

When clicked, the software first tests the instrument connection, and if successful, makes the connection. The instrument connection status is shown in the software Hardware Connection and Settings or Baseband Generator and Channel Simulator tree node. If the connection is successful,the instrument status changes to connected. For example using the signal generator node, Signal Generator (n:Disconnected) changes to Signal Generator (n:Connected). This button is visible while viewing an instrument setting window and only tests the connection for that instrument.

In the following figure, the first signal generator in the list, Signal Generator (0:Connected) is successfully connected to the signal generator identified in the Signal Generator Setting window, VISA Address field. The second signal generator in the list, Signal Generator (1:Disconnected) is not connected to any instrument. The same is also true for the remaining signal generator in the list and the PXB shown under the Baseband Generator and Channel Simulator node.

The Test Connection button does not test the signal generators listed in the PXB Setting window. If there is a need to test those connections, use the Signal Generator selection under the Hardware Connection and Settings node.

Execute

Button Location: Test Setting windows

Click this button to perform the following functions:

downloads all instrument settings and the waveform to the selected and supported instrument(s)
sets the instrument RF output state, and if a component of the signal, the AWGN state
places a copy of the waveform on the PC hard drive whether Offline Mode is enabled or not.
generates the SCPI list that is accessed through the Tools drop-down menu

This button performs the same function as the Execute selection in the Control (O) drop-down menu and it is visible while viewing a test settings window.

For some tests, the software may take a little time to generate all of the signals such as for the LTE Clause 8 test 8.2.3 using the FRC A3-1. This test can take up to a minute to download depending on items such as the CPU, connection, etc. The software displays a progress bar during the signal generation.

W-CDMA Clause 7 Tests—Additional Execute Behavior

Because some of these test signal waveform files can be large (approximately 39 Msa) and they can take more time to download, the software minimizes the time for making changes to the test setup after the initial Execute action. Upon subsequent Execute clicks, the software optimizes test signal changes by downloading only the test parameter change provided that the change is in the current test Settings Window and it is not a change to the Signal Generator selection. If the Signal Generator selection is changed, then the software downloads the previously generated waveform file and instrument settings to the signal generators.

The software generates and downloads the waveform file upon subsequent Execute actions if any of the following occurs:

Common Settings node parameter change
another test selection (downloads the waveform files for the new test selection)

Stop

Button Location: Test Setting windows

This button is active (available) after the following conditions have been met:

the software has a valid instrument connection
the Execute button was clicked
the settings were successfully downloaded to their respective instrument

For the PXB, click this button to stop the signal playback and to turn off the signal generator RF output.

For signals downloaded to the signal generators, click this button to turn off the waveform playback or real-time application, and the RF output.

To restart the signals, click the Execute button. This typically downloads all of the settings and starts the tests.

Restore Default

Button Location: All windows

Click this button to restore the factory default settings to the current tree selection. This button differs from the Preset selection found in the File drop-down menu in that Restore Default restores only the current tree selection to factory default settings. For example, if the TDD test 7.2 Reference Sensitivity Level is the current tree selection and parameters have been changed, clicking Restore Default resets all 7.2 test parameters to factory default settings. If FDD is the current tree selection, clicking Restore Default resets all parameters for all of the tree selections under FDD to factory default settings.
