CAMBOARD Electronics Using the Emulation Mode The VTG 400/400D Control Program features an emulation mode so that you can configure the VTG before actually using it on site. In emulation mode, you can save the emulated settings to a configuration file, then load that configuration file to the VTG.
Page 60
Save the configuration by selecting Save Configuration from the File drop- down menu. If the program is closed while in emulation mode, all settings are saved to the current configuration file www.camboard.de Tel. 07131 911201 ce-info@camboard.de 3-24 VTG 400/400D • Serial Communication Fax 07131 911203...
The VTG 400/400D’s firmware is upgraded by going to the Extron Web site, downloading the latest firmware to the PC, then uploading and installing the new firmware from the PC to the VTG 400/400D via the video test generator’s RS-232 port.

The PLUGE pattern contained in the lower right section of the pattern is used to set proper black level as described for the dedicated PLUGE pattern available from the VTG 400. The small complimentary color rectangles at the bottom of the larger color bars are used to facilitate color and tint calibration.
Note that composite NTSC video utilizes a 7.5 IRE setup pedestal for the black level. The S-video format is likely to include the setup pedestal depending on the source system and the methodology for signal creation. The VTG 400 includes the setup on the S-video luminance signal output and on the component Y channel output.
For situations requiring display of any one of the primary or secondary colors as a flat field, the user may enter into the VTG 400 video setup menu and turn On or Off combinations of the primary output channels. Also note that this feature is available to modify the color of most all the test patterns.
This capability is used when evaluation under conditions of random performance is desired. See the automatic version of the APL bounce pattern for more information. www.camboard.de Tel. 07131 911201 ce-info@camboard.de VTG 400/400D • Appendix A-15 Fax 07131 911203...

The H pattern represents simple text that can be used to evaluate image sharpness or overall response quality using symbology that anyone can understand. The invert soft key on the VTG 400 reverses the text from white text on a black background to black text on a white background.
