DVG7 Digital Video Generator module
To select the test signal
All of the signa
l sets that are available in the module are already assigned to the
corresponding test signal buttons. When the DVG7 module is selected and you
press any of the front-panel test signal buttons, the selected signal in the signal set
is output. (See Figure 3-41.) For example, when you press the COLOR BAR test
signal button, a signal in the Color Bars signal set is output.
Use the left (◄)orright(►) arrow button, or press the COLOR BAR test signal
button repeatedly to select a different signal from the Color Bars signal set.
