Marshall

Pattern Selection Tab

This page allows quick selection of any available test pattern including four User-Defined patterns. (User-Defined patterns do not have icons). User-Defined patterns are uploaded to the V-SG4K-3G using the Pattern Uploader application.

Note that the "Pathological" pattern is available only in SDI mode as it is specifically designed for testing SDI interfaces.

www.marshall-usa.com13 14

Setting Tab

This page contains a collection of settings for video and audio.

Note that the choice for YUV 4:2:0 is available only when the generator is in HDMI mode and a UHD 50, 59.94 or 60 fps pattern is selected. In this mode, the signal generated is compatible with HDMI 2.0.

TV EDID Tab

This page allows testing HDMI EDID (Extended Display Identification Data). It has no application for SDI interfaces.

EDID is a set of information stored in a display device (monitor or projector) by the display manufacturer. In normal operation, this information is retrieved by a source device such as a set top box, media player, etc. when it is connected or powered on. EDID is intended to allow a source device to change its settings to match the display device. This process is invisible to the user.

The V-SG4K-3G Test Pattern generator allows inspection of this EDID information to help with trouble shooting, product development, equipment test and QC.

Using the EDID function

Click on the READ EDID button to capture EDID data directly from a connected display device when the window below the button says "TV EDID". Also, EDID data that has been previously captured and saved in the V-SG4K-3G may be accessed by selecting "Saved 1 - 6" in the pulldown window below the button.

The EDID information is organized in three zones on the page:

General Info – Details about the manufacturer and specifications.

Video Information – A list of all video formats, frame rates, and standards that will be compatible with the device.

Audio Information – A list of all audio formats and standards that will be compatible with the device. There is generally a lot of information in these windows. It may be necessary to scroll through the information to see all the possible options.

Information from the READ EDID function may be stored on the local PC by clicking on the SAVE EDID button. Each time SAVE EDID is clicked, a pair of files is saved to the PC. The files are saved to the same location as the Control Application. EDID saved files are automatically named and numbered sequentially and appear like this:

SigGen_EDID02.bin

SigGen_EDID02.txt

Marshall

V-SG4K-3G Manual

There is no limit to the number of EDID files that can be saved on a PC. Files may be renamed for convenience as long as the ".bin" and ".txt" extensions are not changed. For example, the two files above may be renamed something like:

BigMonitor1.bin

BigMonitor1.txt

Files saved on a PC may be opened later for more analysis by clicking on the OPEN EDID button and browsing to the file.

Note: The WRITE EDID button does not apply to the V-SG4K-3G signal generator and remains "grayed out."

TIP! You may prefer to do Step 3 before Step 2 to save time.

Please Note: An uploaded User Pattern will be available after the V-SG4K-3G has been turned off and back on again.

10. Troubleshooting

If you experience difficulties, try these tips:

No video out.

- Check the HDMI/SDI button.

• n the MENU, turn Signal Output ON.

• In the MENU, turn HDCP Setting OFF.

- Try a different video format / frame rate to find one that is compatible with the device being tested.

"EDID Invalid" Message

- Try a different HDMI cable. Some cables are not properly configured to test all functions.

- Try a different input on the attached device.

- Try powering the device Off and On.

USB connection not recognized by host PC

- Be sure to use a mini-USB cable, not a USB "Micro" cable.

- Try reconnecting the cable. This should "wake up" the USB port on the PC. Allow several minutes for the PC to recognize the device and find the correct driver. This is particularly true for Windows 10 which may reach out to the Web to locate a driver.

- If the USB interface is not recognized by the PC and you wish to install a driver manually, you may download the latest FTDI driver here:
