AWVG1 Wideband Video Generator User Manual
If you disable the module output, it releases all system resources used by this
module. To disable the module output, follow these steps:
1. Select the module, if not already selected.
2. Push the Test Signals button.
3. Touch Module Parameters at the bottom of the screen. The Module
Parameters window (shown on page 2- -16) appears.

5. Touch Quit to exit.
You can set the horizontal and vertical timing of the AWVG1 Generator module
with respect to the BG1 Generator module, using the Module Parameters
window. Changes you make to timing affect all signals for the AWVG1
Generator module. To set the timing, perform the following steps:
1. In the Module Parameters window, shown on page 2- -16, touch the module
timing icon. The Timing window appears.
2. Set the horizontal timing of this module with respect to the BG1 Generator
module as follows:
a. Touch H Feel to select Coarse. (A front-panel knob increment is now
equal to a full cycle of the sample clock, typically 72 MHz.) Rotate the
navigation knob to select the approximate value; rotate counter-clock-
wise to advance the timing, or clockwise to delay the timing.
b. Touch H Feel to select Fine. (Knob increments are now subclock
cycles.) Rotate the knob to select the final value.
