Portable automatic test instrument for video displays and generators
First Claim
1. A portable analyzer for testing video devices, comprising:
- a portable chassis;
a programmable video generator and analyzer housed in said chassis and adapted to be connected to at least one video device being tested, said video generator and analyzer including generating means for generating various forms of video test signals;
a signal conditioner/switching device housed in said chassis and adapted to be connected to the at least one video device being tested, said signal conditioner/switching device being coupled to said video generator and analyzer and including at least one emulator arranged between the at least one video device and said video generator and analyzer to modify signals from the at least one video device and provide the modified signals to said video generator and analyzer;
a command module housed in said chassis; and
a portable computer including a monitor, said computer being arranged to communicate with said video generator and analyzer and said signal conditioner/switching device via said command module in order to conduct test operations and enable display of test results on said monitor;
wherein said at least one emulator provides scaling and signal-conditioning of an input voltage, translates an input signal level to differential Positive Emitter Coupled Logic (PECL), or provides a Transistor-Transistor Logic (TTL) level digital trigger signal and a TTL level gate signal, according to input signals.

Abstract
Portable automatic video device tester including a programmable video generator and analyzer, a signal conditioner/switching device, a command module, a portable computer (laptop) with an integral monitor and a portable VXI chassis for housing the video generator and analyzer, the signal conditioner/switching device and the command module. The programmable video generator and analyzer is connected to one or more video devices being tested and includes a generating mechanism for generating various forms of video test signals. The signal conditioner/switching device is also arranged in connection with the chassis and adapted to be connected to one or more of the video devices being tested. The computer communicates with the video generator and analyzer and the signal conditioner/switching device via the command module in order to conduct test operations and enable display of test results on the monitor.

23. A method for testing a video device including a video source and a video display, comprising:
-
connecting the video source to a portable automatic video test analyzer; capturing video from the video source by means of a video capture module in a programmable video generator and analyzer in the automatic video test analyzer; formatting the captured image in the video generator and analyzer and displaying the formatted image on a monitor of a portable computer coupled to the programmable video generator and analyzer to enable analysis of output from the video source; generating video test signals in the programmable video generator and analyzer; directing the video test signals to the video display to thereby enable analysis of the displayed test signals; and coupling a signal conditioner/switching device in the automatic video test analyzer to and between the programmable video generator and analyzer and the video device, the signal conditioner/switching device including at least one emulator arranged between and coupled to the video device and the programmable video generator and analyzer to modify signals from the video device and provide the modified signals to the programmable video generator and analyzer;
wherein said at least one emulator provides scaling and signal-conditioning of an input voltage, translates an input signal level to differential Positive Emitter Coupled Logic (PECL), or provides a Transistor-Transistor Logic (TTL) level digital trigger signal and a TTL level gate signal, according to input signals. - View Dependent Claims (24, 25, 26, 27)
