Creating and Exporting Waveforms for the EXT

Some Signal Studio software products do not provide direct connectivity to the Keysight E6607 EXT Wireless Communications Test Set. In these cases, waveforms licensed to play on the EXT must be created in simulated hardware mode, exported to a waveform file, and then loaded into the EXT via a USB storage device. This procedure describes how to create and transfer waveform files to your EXT for playback using this method.

If available, a direct connection to the EXT is more convenient to use than the export method described here. To determine if this Signal Studio product provides direct connectivity to the EXT, open the software and select New hardware configuration in the system configuration wizard. The EXT will be one of the supported hardware configuration choices, if direct connectivity is available.

This procedure uses Keysight Signal Studio for LTE-LTE-Advanced FDD as an example, but the steps are valid for all Signal Studio software applications that support the EXT.

  1. Open the software. The welcome dialog window appears.

    If the welcome dialog window does not appear when the software is launched, click Tools > Options and make sure Display Welcome dialog is checked. Then close and re-open the software.

  2. Select Simulated hardware and make sure RF Output (for Signal Generator) is highlighted. Click OK.

  3. Because simulation mode offers all possible capability options, the caution shown below may appear. Whether the caution appears or not, however, you must set any unpurchased licenses to OFF, otherwise the generated waveform cannot be played back in the EXT. If your software's interface does not provide access to a Licenses node where this is performed, proceed to step 6.

  4. In the software's tree view, click Licenses. Notice that in simulated hardware mode, all software licensing options are set to On.

  5. In the State column, click the cell to turn off any options you did not purchase. This is necessary to create a valid waveform for playback on your EXT. This example assumes the advanced option was not purchased for the EXT.

  6. Configure the Signal Studio waveform using the various parameter selections and settings available under the Waveform Setup node in the tree view. Waveform parameters vary among Signal Studio products, so refer to this help system for more information.

  7. Click the Generate Waveform button.

  8. Under the File menu, select Export Waveform Data.

  9. Name the waveform file and save it to your PC.

  10. Copy the waveform file to a portable USB storage device.

    This would be a good time to also save a backup copy of the waveform file.

  11. Insert the USB storage device into the EXT's front panel USB port.

  12. On the EXT, make sure the EXT user interface is the active window and press File > File Explorer. Then locate the USB storage device and copy your waveform file to D:\NVARB. You can navigate to this folder by selecting My Computer > User Data (D:) > NVARB.

  13. On the EXT, press Source > More 1 of 2 > Modulation Setup > ARB > More 1 of 2 > Select Waveform > Segments on Hard Disk. Then use the arrow keys or mouse to select a waveform file from NVARB memory.

    The EXT's user interface uses the term segment to refer to a waveform file.

  14. Press Load Segment to ARB Memory.

  15. Now that the waveform resides in the EXT's ARB memory, press the Return key and select the waveform for playback. Use the EXT's front panel and softkey menus to set up other ARB parameters, turn ARB modulation on, set frequency and amplitude, and turn RF output on. You can also examine the waveform, using the EXT's measurement functions. Refer to the EXT's user documentation for more information.
