Page 3: Getting Started
Getting Started Using AC Power Use only the AC adaptor provided with the generator to avoid operator injury and damage to the gen- erator. Using Battery Power The generator uses six AA rechargeable nickel metal hydride (NiMH) batteries, which can be recharged about 1000 times. -

Page 8: Setting Power Save Preferences
Setting Power Save Preferences Options Menu Press the Options button to set system-level options. Hot Plug:In Setting Power Save Preference When the Power Save preference is on, and the generator is on battery power, the generator will turn off after 30 minutes of no front panel activity. If the generator is running a test sequence in Burn-in mode, the Power Save preference is ignored. -
Page 9: Calibrating Generator
Calibrating Model 700A and 701A generators use programmable hardware to set the amplitude calibration factors for analog video outputs. These calibration factors are stored in Flash EPROM, and are not lost if the batteries are run down or removed. Quantum Data calibrates the analog video and sync output amplitudes in new generators to published specifications. - Page 10 Calibrating Calibrating Outputs Select Options > Calibrate > Reset to set the generator’s calibra- tion factors to default nominal values. Press Options > Calibrate > Full Scale. ����������������� � ������������������������ Set the voltmeter’s scale factor to be able to measure a nominal ������...

Page 11: Adjusting Horizontal Scan Frequency
Calibrating Locking Calibration Settings The generator uses an internal hardware jumper to enable and disable changes to calibration settings. If the Options > Calibration option is available, the jumper is set to enable re-calibration. To prevent users from changing calibration settings: Turn the generator off, and remove the back cover. -

Page 16: Generating Psuedo Random Noise
Special Tests Generating Pseudo Random Noise When the generator is connected to a device that supports the Quantum Data pseudo random noise standard, press Test > PR Noise to output the noise pattern as a static image. Depending on how the device is designed, it may compare the pattern output by the generator with an identical pattern, created internally, to detect errors in the cable and in the device itself. -
Page 17: Using Video Generator Manager
As many as 132 formats and one test sequence can be stored in the generator. VGM was originally created for use with Quantum Data 80x video generators. The 700A-Series genera- tors support only some VGM features. For information about using VGM, see the VGM help file. -
Page 18: Creating Video Formats
Creating Video Formats Editing Video Formats You can use VGM to create your own video formats. You can start with a default format in the VGM format editor, or copy an existing format. To create a video format: Connect the generator with VGM, and then double-click the generator name. Click the View Formats icon to list the available formats. -
Page 19: Modifying Test Sequence
Modifying Test Sequence Editing the Test Sequence The generator has a default sequence, which you can edit in VGM. One sequence can be stored in the generator at the same time. To modify the test sequence: Connect the generator with VGM, and then double-click the generator name. In the generator window, click the Sequence List icon to display the sequence name. -
Page 20: Pattern Descriptions
Pattern Descriptions Flat_Wht/(R,G,B) Description - Fills the screen with white, blue (B), green (G) or red (R). Application - Use to test chrominence. Grid Decription - White crosshatch on a black background. The lines form square boxes. A single pixel dot is located in the center of each crosshatch box. - Page 21 Pattern Descriptions the entire screen, in a large portion of the screen, or localized in a very small area. Raster Description - Black display (nothing being displayed). Application - Useful for centering the raster on a CRT. Many monitor applications require that the dis- played image or text fit completely within a bezel that surrounds the CRT.
- Page 22 Pattern Descriptions Regulate Description - The image has a pair of white outlined boxes which surround a blinking solid white box. Application - Tests for proper high voltage regulation. Checker Description - The image’s active video area is equally divided into a 6x6 checkerboard of black and white boxes.
- Page 23 Pattern Descriptions Application - Useful for testing pixel anomolies and chrominance. PulseBar Description - The image looks like two vertical lines followed by a wide vertical bar on a display’s screen. The first line is a red pulse. The pulse is 20 T for PAL and 12.5 T for NTSC formats. The second narrower line is a 2 T white sine-squared pulse.

Page 24: Updating Firmware
Updating Firmware Updating Firmware The generator’s operating system firmware is stored in Flash EPROM, which you can update via the se- rial port. Firmware updates are available from http://www.quantumdata.com/support/downloads/. To install a firmware update: Turn ON the generator and connect it to your PC using a null modem serial cable. Start HyperTerminal with the proper communications setup (9600 bps, 8 data bits, no parity, 1 stop bit, Xon/Xoff flow control). -
