Abstract:
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.
