Using the TVM-VTM-3GB as a Monitor

The 3Gb/s WFM/VEC mode is the best method to monitor the 3Gb/s video formats

and frame rates. Resources from other functions are needed to display 3Gb/s signals so

there are restrictions to audio lissajous and the number of vector and waveform panes.

When 3Gb/s mode is selected only one input can be displayed at a time. Once the

3Gb/s signal input is selected, the waveform, vector, picture, and audio will reflect the

current input signal condition. The Waveform, Vector, Audio, and Picture display

panes function the same as described in their appropriate sections.

The 3Gb/s mode produces the following changes in the TVM:

• The same video input is displayed in the four panes.

• Picture gamut highlighting is disabled in 3Gb/s WFM/VEC mode. Further, the

picture will only show half of the video lines in 1080p/50/59.94/60 formats.

• There is no audio Lissajous in 3Gb/s WFM/VEC mode. Also, if two or four

channels of audio are displayed, the TVM will automatically switch into an eight-

channel configuration.

• Waveform and Vector displays show all lines for each frame. When not in 3Gb/s

WFM/VEC mode, half of the lines are displayed.

• When performing a data capture, FREEZE + LIVE is not available.

Using the TVM-VTM-3GB as a Test Signal Generator

NOTE: The video output format is restricted to 10-bit YCBCR signals.

NOTE: The MONITOR OUT/GENERATOR A-B menu only appears in the Setup menu if the

TVM-VTM-3GB board appears in slot 1.

NOTE: The MONITOR OUT/GENERATOR C-D menu only appears in the Setup menu if the

TVM-VTM-3GB board appears in slot 2.

The TVM-VTM-3GB can be used as a signal generator. Using the MONITOR

OUT/GENERATOR A-B or MONITOR OUT/GENERATOR C-D setup menu, set the

3GB option to output a Monitor, Pathological, Colorbar, or Colorbar with Motion

display using one of the video formats listed below. The TVM-VTM-3GB can also be

used to output a -18 dBFS or -20 dBFS tone to a maximum of 4 different audio groups.

The available video output signals are as follows:

• 1080i/59.94

• 1080i/50

• 1080p/59.94

• 1080p/50

• 720p/59.94

• 720p/50

• 625/50

• 525/59.94
