BG1 Black Burst Generator User Manual

Getting Started

Getting Started

The BG1 Generator module is a multiple-format black burst generator. The
module can supply one of the six following black burst signals on the three
rear-panel output connectors:

 NTSC with setup and no color frame reference
 NTSC with setup and color frame reference
 NTSC without setup
 NTSC without setup and with color frame reference
 PAL with color frame reference
 PAL without color frame reference

You can select the rear-panel Clock Out signal from the following signals:

 The 27 MHz master clock
 Two Direct Digital Synthesis (DDS) clocks, which you can set from 10 MHz

to 100 MHz
 Two frame reset pulses

The timing of the outputs is time zero for reference timing. The output timing
cannot be delayed.

The BG1 Generator module is supplied as a standard accessory with the
TG 2000 Signal Generation Platform.

NOTE. If the black burst or clock outputs are not required, the BG1 Generator
module can be removed to provide a mainframe slot for another module.

Configuration

Installation

The module does not require any hardware configuration. You cannot reconfi­gure the signal outputs.

The module should be installed by qualified service personnel only. Refer to
Appendix C for detailed instructions on how to install the module.

The module is shipped with the signal sets already installed. You cannot change
the signals or signal sets for this module. (The SDP2000 Signal Development
Program cannot create signals for the BG1 Generator module.) However, you can
use an AVG1 Generator module to generate similar signals.

Functional Check

Getting Started

This procedure determines if your module is operating correctly. If you are not
familiar with the operation of the module, it may be helpful to refer to Figure
2–1 on page 2–1 while performing this procedure.

Required Equipment

Procedure

For this procedure, you will need a television monitor and a frequency counter or
an oscilloscope.

To check your module, follow these steps:

1. If the module is not installed in the TG 2000 Platform mainframe, install the

module, using the installation procedures beginning on page C–2.

2. Power on the TG 2000 Signal Generation Platform. The platform runs a self

test on all modules.

3. To determine if the self test was successful, press the Modules button.

Check the display for the icon that represents the BG1 Generator module.

4. Push the Modules button and touch the BG1 icon on the display.

5. Select either the NTSC or the PAL signal set.

6. Select Black Burst (the black burst signal without color frame reference).

7. Connect the BG1 Generator module Output 1 signal to the television

monitor.

8. Set the monitor to the pulse-cross setting so that you can see the signal

blanking areas.

9. Select Black Burst + Frm Ref (the black burst signal with color frame

reference).

10. Check that the color frame reference signal appears as expected.

11. For NTSC users only, push the Signal Sets button, and then select the

NTSC no Setup signal set. Select a signal and check that the signal

displayed on the monitor changes appropriately.

12. Connect the Output 2 signal to the monitor. Check that the signal that was on

Output 1 appears on Output 2.

13. Repeat step 12 for Output 3.

14. Connect the Clock Out signal to the frequency counter or oscilloscope.

15. From the Test Signals window, touch Module Parameters.

16. Touch Clock Out.
