Sorry about the photograph quality - taken at night and the camera shutter speed wouldn't go fast enough to get a crystal clear picture
Quantam Data Video Generator
Designed/manufactured in USA
Model 801GC
Standalone video generator
Small, compact
Steel outer casing, built to withstand field conditions
The 801GC is a portable video signal generator designed for basic testing and alignment of various types of raster-scanned displays.
The generator is shipped with over 100 signal formats built-in for driving a variety of industry-standard displays.
Formats for other displays can be added using the built-in graphics user interface editor or a PC or terminal via the built-in RS-232 and IEEE-448 interfaces.
Formats are stored in a non-volatile memory.
Memory capacity for up to 300 formats.
Permanent copies of industry-standard formats are stored (along with the generator's operating code) in EPROM and can be copied into format memory and modified as required.
The 801GC features over 50 test images that allow a wide variety of display criteria to be checked. The generator has an image loop feature that can be used for monitor burn-in or at trade shows to display a series of images over and over.
User defined custom test images can also be created and saved in
non-volatile memory
The range of formats is truly extensive, ranging from TTL to IBM Workstation to Sun equipment - the list of formats covers 3 pages of tables in the manual.
The user manual is provided in electronic format. It is very detailed at 370 pages and includes programming information to setup your own display formats and also error code information.
Backup of custom formats is enabled by a small 3V flat Lithium battery - this is a type 2325 and needs replacing. Now the unit still operates fine without this battery but you will not be able to store your custom formats if you are using this feature.
COSMETIC CONDITION:
Both caps to the control knobs are missing - this in no way affects operation though.
Clean and without any case damage or socket damage
TESTING:
Upon power up, the unit performs a self test of both memory and the Eproms - all is fine and passed.
Then using the VGA ouput socket, I checked various formats/test images up to 1024 x 768 - this is when I noticed something was not quite right.
The video generated is fine HOWEVER just sometimes the pattern could not be changed, as though the system was locked up. I could not move away from the VGA outputs or select various formats within VGA. However power off then on again, everything would be fine next time around.
So it is working fine and when it was running ok, I went through many different formats to check them all - video is excellent, just control of the format was sometimes not possible at turn-on (no error messages though)
