  • 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 generator. Using Battery Power The generator uses six AA rechargeable nickel metal hydride (NiMH) batteries, which can be re- charged about 1000 times.

  • Page 6: Selecting Formats

    Selecting Formats Viewing Formats by Signal Type Press the Signal Type button, and then select a signal type, to list formats based on the selected signal type. VESA Red, green, blue component color video per VESA standards. (DVI-to-VGA adaptor used for outputs.) NTSC/PAL Composite color baseband video signal (BNC connector) and Separate Luminance and Chrominance video signals (S-Video connector) or RGB component video per NTSC and PAL standards.

  • Page 7: Selecting Images

    Selecting Images Selecting Images Press the Image button to select from list of available test images (patterns). You cannot modify the images, or add your own images. Gating Outputs Press the Gating button to gate outputs, and to switch sync types. Note: Color gating works for all images except Ramp.

  • Page 8: Setting Power Save Preferences

    Setting Power Save Preferences Options Menu Press the Options button to set system-level options. 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: Equipment Needed For Calibration

    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 pub- lished specifications. You can recalibrate these amplitudes over a nominal range to meet your specific testing conditions.
  • Page 10 Calibrating Calibrating Outputs Select Options > Calibrate > Reset to set the generator’s calibration factors to default nominal values. Press Options > Calibrate > Full Scale. Set the voltmeter’s scale factor to be able to measure a nominal 1000 millivolts DC. Using a VGA-to-BNC cable, connect the generator’s red output to the positive input on the voltmeter, with a 75 ohm (+/- 1%) input terminator.

  • 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 12: Detecting Formats Supported By A Monitor

    Detecting Formats Supported by a Monitor Learn Monitor If the generator is connected to a VESA DCC- compliant display, press the Learn Monitor button to view formats supported by both the display and generator. To view the format names, select the Details option after the generator completes reading the EDID (Extended Display Identification Data) data.

  • Page 13: Using Test Sequences

    Using Test Sequences Test Menu Press the Test button to select special test operating modes. Running Test Sequence Manually The generator includes a test sequence, which specifies a series of format and image combinations. To run the test sequence, select Test > Sequence > Run, and then press the +/- buttons to step through the sequence.
  • Page 14 Using Test Sequences Running Test Sequence in Burn-In Mode Select Test > Burn-In > Run to automatically cycle through the test sequence. When the Burn-In mode is stopped, you can use the menu buttons to gate video color information, change sync types, and turn all signal outputs on and off.

  • Page 15: Special Tests

    Special Tests Using Generator with CS-1 Probe The Test > CS1 Probe option uses the Quantum Data CS-1 color sensor to measure the chromaticity and luminance (brightness) of a display. The CS-1 probe connects to the generator’s serial port. Chromaticity is shown as x,y C.I.E. coordinates and the luminance (Y) can be shown either in units of foot-Lamberts or nits.

  • Page 16: Generating Psuedo Random Noise

    To stop the test, press the Exit soft key or any gray key. 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 700-Series generators support only some VGM features. For information about using VGM, see the VGM help file.

  • Page 18: Creating Video Formats

    The format editor works as described in the VGM help file, except that the physical size entries have no affect on how test images are displayed on the 700 series. However, the integer portion of the horizontal size in millimeters specifies the storage location of the format in the generator.

  • 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 Right-click the sequence name, and then select Edit to open the Sequence Editor.

  • 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 present across 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 displayed 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 Ramp Description - This image provides an active video area starting from full black (+7.5 IRE for NTSC) at one edge of the screen to full white (+100 IRE) at or near the opposite end of the screen. Application - Useful for testing pixel anomolies and chrominance.

  • 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 serial port. Firmware updates are available from http://www.quantumdata.com/support/downloads/. To install a firmware update: Turn off generator, and connect it to your PC using a null modem serial cable. Hold down the upper-right menu button, and then press the On/Off button.
